-# This is a bit complicated for two reasons:
-# - we really want to run dnf/apt/... only once, updating on the test runner for
-#   each job takes forever. So we create a container image for each distribution
-#   tested, then run the tests on this container image.
-#
-#   This is handled by the ci-templates, ensuring containers are only rebuilt
-#   when the TAG changes.
-#
-# - GitLab only allows one script: set per job but we have a bunch of commands
-#   we need to re-run for each build (meson && ninja && etc). YAML cannot merge
-#   arrays so we're screwed.
-#
-#   So instead we use a default_build template and override everything with
-#   variables. The only two variables that matter:
-#     MESON_ARGS=-Denable-something=true
-#     NINJA_ARGS=dist ... to run 'ninja -C builddir dist'
-#   Note that you cannot use scripts: in any target if you expect default_build
-#   to work.

-#
-# All jobs must follow the naming scheme of
-# <distribution>:<version>@activity:
-#  e.g. fedora:31@build-default

-      Hi. This issue or merge request needs help. This simply means that for
-      the foreseeable future, the maintainers will not have time to work on
-      this.
-
-      If this is a request for a new feature, then the feature is unlikely to
-      be implemented unless you or another contributor files a merge request.
-      If a merge request already exists maybe it needs finishing which often
-      involves adding documentation or tests.
-
-      If this is an issue affecting a specific device then it is unlikely to be
-      fixed. This may be because it requires specific hardware to reproduce or
-      it may be that the use case is niche enough that the maintainers do not
-      have time to implement it.
-
-      In short, to resolve this issue or get this merge request into libinput
-      help is needed.

-      This issue looks like it could or should be fixed with [udev-hid-bpf](https://gitlab.freedesktop.org/libevdev/udev-hid-bpf/).
-      udev-hid-bpf is a collection of BPF programs that modify the HID Report Descriptor and/or HID Reports from the device,

-      expectations the kernel and userspace has of such devices.

-            Looks like this issue may be solved with a device-specific entry in systemd's hwdb.
-
-            You should have a /usr/lib/udev/hwdb.d/60-evdev.hwdb file which includes those quirks. Please see
-            the top of the file for instructions and follow those. Once the quirk is confirmed working
-            this issue (or parts thereof) should be fixed and you can submit a pull request to the
-            [systemd](https://github.com/systemd/systemd/) repository to get that quirk included.
-            Please link to the systemd issue here, thanks.
-
-            I'm closing this issue now, if the hwdb entry does not fix this issue here, please re-open.

-            I'm temporarily closing this bug. The bug may not be fixed yet (see any comments above)
-            and we **want you to reopen it when/if it becomes actionable again**.
-
-            This process may feel unfamiliar but unfortunately closing/re-opening is the only action
-            all GitLab users are permitted to do. So we close it, you re-open it when whatever
-            above has been addressed and then we know we need to look at it again.
-            This issue may be closed more than once in a similar fashion but I only leave this
-            comment once since now you understand how it works. :smile:

-            Hi. Thanks for the merge request. I'm here to request that you add
-            some documentation about this merge request to the
-            **commit message** (or messages). You may have already written some
-            in the merge request description and in many cases it's fine to
-            copy/paste that into the commit message(s).
-
-            The reason is simple: once merged, no-one really looks at this this
-            page here anymore. The git log on the other hand is what developers
-            will use to understand the code so the information must be quickly
-            accessible via git.
-
-            Please see [our docs for submitting code](https://wayland.freedesktop.org/libinput/doc/latest/contributing.html#submitting-code)

-
-# Git commit message requirements
-
-Our CI will check the commit messages for a few requirements. Below is the
-list of what we expect from a git commit.
-
-## Commit message content
-
-A [good commit message](http://who-t.blogspot.com/2009/12/on-commit-messages.html) needs to
-answer three questions:
-
-- Why is it necessary? It may fix a bug, it may add a feature, it may
-  improve performance, reliabilty, stability, or just be a change for the
-  sake of correctness.
-- How does it address the issue? For short obvious patches this part can be
-  omitted, but it should be a high level description of what the approach
-  was.
-- What effects does the patch have? (In addition to the obvious ones, this
-  may include benchmarks, side effects, etc.)
-
-These three questions establish the context for the actual code changes, put
-reviewers and others into the frame of mind to look at the diff and check if
-the approach chosen was correct. A good commit message also helps
-maintainers to decide if a given patch is suitable for stable branches or
-inclusion in a distribution.
-
-## Commit message format
-
-The canonical git commit message format is:
-
-```
-one line as the subject line with a high-level note
-
-full explanation of the patch follows after an empty line. This explanation
-can be multiple paragraphs and is largely free-form. Markdown is not
-supported.
-
-You can include extra data where required like:
-- benchmark one says 10s
-- benchmark two says 12s
-```
-
-The subject line is the first thing everyone sees about this commit, so make
-sure it's on point.
-
-## Commit message technical requirements
-
-- The commit message should use present tense (not past tense). Do write
-  "change foo to bar", not "changed foo to bar".
-- The text width of the commit should be 78 chars or less, especially the
-  subject line.
-- The author must be the name you usually identify as and email address. We do
-  not accept the default `@users.noreply` gitlab addresses.
-  ```
-  git config --global user.name Your Name
-  git config --global user.email your@email
-  ```

+libinput
+
+libinput is a library that handles input devices for display servers and other
+applications that need to directly deal with input devices.
+
+It provides device detection, device handling, input device event processing
+and abstraction so minimize the amount of custom input code the user of
+libinput need to provide the common set of functionality that users expect.
+
+Input event processing includes scaling touch coordinates, generating
+pointer events from touchpads, pointer acceleration, etc.
+
+libinput originates from weston, the Wayland reference compositor.

-/**
-@mainpage
-
-This is the libinput API reference.
-
-This documentation is aimed at developers of Wayland compositors. User
-documentation is available
-[here](https://wayland.freedesktop.org/libinput/doc/latest).
-
-@section concepts Concepts
-
-@subsection concepts_initialization Initialization of a libinput context
-
-libinput provides two different backends:
-- a @ref libinput_udev_create_context "udev backend" where notifications
-  about new and removed devices are provided by udev, and
-- a @ref libinput_path_create_context "path backend" where
-  @ref libinput_path_add_device "device addition" and
-  @ref libinput_path_remove_device "device removal" need to be handled by
-  the caller.
-
-See section @ref base for information about initializing a libinput context.
-
-@subsection concepts_events Monitoring for events
-
-libinput exposes a single @ref libinput_get_fd "file descriptor" to the
-caller. This file descriptor should be monitored by the caller, whenever
-data is available the caller **must** immediately call libinput_dispatch().
-Failure to do so will result in erroneous behavior.
-
-libinput_dispatch() may result in one or more events being available to the
-caller. After libinput_dispatch() a caller **should** call
-libinput_get_event() to retrieve and process this event. Whenever
-libinput_get_event() returns `NULL`, no further events are available.
-
-See section @ref event for more information about events.
-
-@subsection concepts_seats Device grouping into seats
-
-All devices are grouped into physical and logical seats. Button and key
-states are available per-device and per-seat. See @ref seat for more
-information.
-
-@subsection concepts_devices Device capabilities
-
-libinput does not use device types. All devices have @ref
-libinput_device_has_capability "capabilities" that define which events may
-be generated. See @ref device for more information about devices.
-
-Specific event types include:
-- @ref event_keyboard
-- @ref event_pointer
-- @ref event_touch
-- @ref event_gesture
-- @ref event_tablet
-- @ref event_tablet_pad
-- @ref event_switch
-
-
-@subsection concepts_configuration Device configuration
-
-libinput relies on the caller for device configuration. See
-@ref config for more information.
-
-@subsection example An example libinput program
-
-The simplest libinput program looks like this:
-
-@code
-static int open_restricted(const char *path, int flags, void *user_data)
-{
-	int fd = open(path, flags);
-	return fd < 0 ? -errno : fd;
-}
-
-static void close_restricted(int fd, void *user_data)
-{
-	close(fd);
-}
-
-const static struct libinput_interface interface = {
-	.open_restricted = open_restricted,
-	.close_restricted = close_restricted,
-};
-
-
-int main(void) {
-	struct libinput *li;
-	struct libinput_event *event;
-
-	li = libinput_udev_create_context(&interface, NULL, udev);
-	libinput_udev_assign_seat(li, "seat0");
-	libinput_dispatch(li);
-
-	while ((event = libinput_get_event(li)) != NULL) {
-
-		// handle the event here
-
-		libinput_event_destroy(event);
-		libinput_dispatch(li);
-	}
-
-	libinput_unref(li);
-
-	return 0;
-}
-
-@endcode
-
-@section building_against Building against libinput
-
-libinput provides a
-[pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/) file.
-Software that uses libinput should use pkg-config and the
-`PKG_CHECK_MODULES` autoconf macro.
-Otherwise, the most rudimentary way to compile and link a program against
-libinput is:
-
-@verbatim
-    gcc -o myprogram myprogram.c `pkg-config --cflags --libs libinput`
-@endverbatim
-
-For further information on using pkgconfig see the pkg-config documentation.
-
-@section stability Backwards-compatibility
-
-libinput promises backwards-compatibility across all the 1.x.y version. An
-application built against libinput 1.x.y will work with any future 1.*.*
-release.
-
-@section About
-
-Documentation generated from git commit [__GIT_VERSION__](https://gitlab.freedesktop.org/libinput/libinput/commit/__GIT_VERSION__)

-   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-   copyright license to reproduce, prepare Derivative Works of,

-   Work and such Derivative Works in Source or Object form.
-
-3. Grant of Patent License. Subject to the terms and conditions of

-   or a Contribution incorporated within the Work constitutes direct
-   or contributory patent infringement, then any patent licenses
-   granted to You under this License for that Work shall terminate
-   as of the date such litigation is filed.
-

-   Work or Derivative Works thereof in any medium, with or without
-   modifications, and in Source or Object form, provided that You
-   meet the following conditions:
-
-   (a) You must give any other recipients of the Work or
-       Derivative Works a copy of this License; and

-
-   (c) You must retain, in the Source form of any Derivative Works
-       that You distribute, all copyright, patent, trademark, and
-       attribution notices from the Source form of the Work,
-       excluding those notices that do not pertain to any part of
-       the Derivative Works; and
-
-   (d) If the Work includes a "NOTICE" text file as part of its
-       distribution, then any Derivative Works that You distribute must
-       include a readable copy of the attribution notices contained
-       within such NOTICE file, excluding those notices that do not
-       pertain to any part of the Derivative Works, in at least one
-       of the following places: within a NOTICE text file distributed
-       as part of the Derivative Works; within the Source form or
-       documentation, if provided along with the Derivative Works; or,
-       within a display generated by the Derivative Works, if and
-       wherever such third-party notices normally appear. The contents
-       of the NOTICE file are for informational purposes only and
-       do not modify the License. You may add Your own attribution
-       notices within Derivative Works that You distribute, alongside
-       or as an addendum to the NOTICE text from the Work, provided

-   reproduction, and distribution of the Work otherwise complies with
-   the conditions stated in this License.
-
-5. Submission of Contributions. Unless You explicitly state otherwise,
-   any Contribution intentionally submitted for inclusion in the Work
-   by You to the Licensor shall be under the terms and conditions of
-   this License, without any additional terms or conditions.
-   Notwithstanding the above, nothing herein shall supersede or modify
-   the terms of any separate license agreement you may have executed
-   with Licensor regarding such Contributions.
-
-6. Trademarks. This License does not grant permission to use the trade
-   names, trademarks, service marks, or product names of the Licensor,
-   except as required for reasonable and customary use in describing the
-   origin of the Work and reproducing the content of the NOTICE file.
-
-7. Disclaimer of Warranty. Unless required by applicable law or
-   agreed to in writing, Licensor provides the Work (and each
-   Contributor provides its Contributions) on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-   implied, including, without limitation, any warranties or conditions
-   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-   PARTICULAR PURPOSE. You are solely responsible for determining the
-   appropriateness of using or redistributing the Work and assume any
-   risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,
-   whether in tort (including negligence), contract, or otherwise,
-   unless required by applicable law (such as deliberate and grossly
-   negligent acts) or agreed to in writing, shall any Contributor be
-   liable to You for damages, including any direct, indirect, special,
-   incidental, or consequential damages of any character arising as a
-   result of this License or out of the use or inability to use the
-   Work (including but not limited to damages for loss of goodwill,
-   work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses), even if such Contributor
-   has been advised of the possibility of such damages.
-
-9. Accepting Warranty or Additional Liability. While redistributing
-   the Work or Derivative Works thereof, You may choose to offer,
-   and charge a fee for, acceptance of support, warranty, indemnity,
-   or other liability obligations and/or rights consistent with this
-   License. However, in accepting such obligations, You may act only
-   on Your own behalf and on Your sole responsibility, not on behalf
-   of any other Contributor, and only if You agree to indemnify,
-   defend, and hold each Contributor harmless for any liability
-   incurred by, or claims asserted against, such Contributor by reason
-   of your accepting any such warranty or additional liability.

-.. _absolute_axes:
-
-==============================================================================
-Absolute axes
-==============================================================================
-
-Devices with absolute axes are those that send positioning data for an axis in
-a device-specific coordinate range, defined by a minimum and a maximum value.
-Compare this to relative devices (e.g. a mouse) that can only detect
-directional data, not positional data.
-
-libinput supports three types of devices with absolute axes:
-
- - multi-touch screens
- - single-touch screens
- - :ref:`graphics tablets <tablet-support>`
-
-Touchpads are technically absolute devices but libinput converts the axis values
-to directional motion and posts events as relative events. Touchpads do not count
-as absolute devices in libinput.
-
-For all absolute devices in libinput, the default unit for x/y coordinates is
-in mm off the top left corner on the device, or more specifically off the
-device's sensor. If the device is physically rotated from its natural
-position and this rotation was communicated to libinput (e.g. by setting
-the device left-handed),
-the coordinate origin is the top left corner in the current rotation.
-
-.. _absolute_axes_handling:
-
-------------------------------------------------------------------------------
-Handling of absolute coordinates
-------------------------------------------------------------------------------
-
-In most use-cases, absolute input devices are mapped to a single screen. For
-direct input devices such as touchscreens the aspect ratio of the screen and
-the device match. Mapping the input device position to the output position is
-thus a simple mapping between two coordinates. libinput provides the API for
-this with
-
-- **libinput_event_pointer_get_absolute_x_transformed()** for pointer events
-- **libinput_event_touch_get_x_transformed()** for touch events
-
-libinput's API only provides the call to map into a single coordinate range.
-If the coordinate range has an offset, the compositor is responsible for
-applying that offset after the mapping. For example, if the device is mapped
-to the right of two outputs, add the output offset to the transformed
-coordinate.
-
-.. _absolute_axes_nores:
-
-------------------------------------------------------------------------------
-Devices without x/y resolution
-------------------------------------------------------------------------------
-
-An absolute device that does not provide a valid resolution is considered
-buggy and must be fixed in the kernel. Some touchpad devices do not
-provide resolution, those devices are correctly handled within libinput
-(touchpads are not absolute devices, as mentioned above).
-
-.. _calibration:
-
-------------------------------------------------------------------------------
-Calibration of absolute devices
-------------------------------------------------------------------------------
-
-Absolute devices may require calibration to map precisely into the output
-range required. This is done by setting a transformation matrix, see
-**libinput_device_config_calibration_set_matrix()** which is applied to
-each input coordinate.
-
-.. math::
-    \begin{pmatrix}
-     cos\theta & -sin\theta & xoff \\
-     sin\theta &  cos\theta & yoff \\
-     0   & 0    & 1
-    \end{pmatrix} \begin{pmatrix}
-    x \\ y \\ 1
-    \end{pmatrix}
-
-:math:`\theta` is the rotation angle. The offsets :math:`xoff` and :math:`yoff` are
-specified in device dimensions, i.e. a value of 1 equals one device width or
-height. Note that rotation applies to the device's origin, rotation usually
-requires an offset to move the coordinates back into the original range.
-
-The most common matrices are:
-
-- 90 degree clockwise:
-     .. math::
-         \begin{pmatrix}
-          0 & -1 & 1 \\
-          1 & 0 & 0 \\
-          0 & 0 & 1
-         \end{pmatrix}
-- 180 degree clockwise:
-     .. math::
-         \begin{pmatrix}
-          -1 & 0 & 1 \\
-          0 & -1 & 1 \\
-          0 & 0 & 1
-         \end{pmatrix}
-- 270 degree clockwise:
-     .. math::
-         \begin{pmatrix}
-          0 & 1 & 0 \\
-          -1 & 0 & 1 \\
-          0 & 0 & 1
-         \end{pmatrix}
-- reflection along y axis:
-     .. math::
-         \begin{pmatrix}
-          -1 & 0 & 1 \\
-          1 & 0 & 0 \\
-          0 & 0 & 1
-         \end{pmatrix}
-
-See Wikipedia's
-`Transformation Matrix article <http://en.wikipedia.org/wiki/Transformation_matrix>`_
-for more information on the matrix maths. See
-**libinput_device_config_calibration_get_default_matrix()** for how these
-matrices must be supplied to libinput.
-
-Once applied, any x and y axis value has the calibration applied before it
-is made available to the caller. libinput does not provide access to the
-raw coordinates before the calibration is applied.
-
-.. _absolute_axes_nonorm:
-
-------------------------------------------------------------------------------
-Why x/y coordinates are not normalized
-------------------------------------------------------------------------------
-
-x/y are not given in :ref:`normalized coordinates <motion_normalization>`
-([0..1]) for one simple reason: the aspect ratio of virtually all current
-devices is something other than 1:1. A normalized axes thus is only useful to
-determine that the stylus is e.g. at 78% from the left, 34% from the top of
-the device. Without knowing the per-axis resolution, these numbers are
-meaningless. Worse, calculation based on previous coordinates is simply wrong:
-a movement from 0/0 to 50%/50% is not a 45-degree line.
-
-This could be alleviated by providing resolution and information about the
-aspect ratio to the caller. Which shifts processing and likely errors into the
-caller for little benefit. Providing the x/y axes in mm from the outset
-removes these errors.

-Coordinate ranges for absolute axes

-
-libinput requires that all touchpads provide a correct axis range and
-resolution. These are used to enable or disable certain features or adapt
-the interaction with the touchpad. For example, the software button area is
-narrower on small touchpads to avoid reducing the interactive surface too
-much. Likewise, palm detection works differently on small touchpads as palm
-interference is less likely to happen.
-
-Touchpads with incorrect axis ranges generate error messages
-in the form:
-<blockquote>
-Axis 0x35 value 4000 is outside expected range [0, 3000]
-</blockquote>
-
-This error message indicates that the ABS_MT_POSITION_X axis (i.e. the x
-axis) generated an event outside the expected range of 0-3000. In this case
-the value was 4000.
-This discrepancy between the coordinate range the kernels advertises vs.
-what the touchpad sends can be the source of a number of perceived
-bugs in libinput.
-
-.. _absolute_coordinate_ranges_fix:

-Measuring and fixing touchpad ranges
-------------------------------------------------------------------------------
-
-To fix the touchpad you need to:
-
-#. measure the physical size of your touchpad in mm
-#. run the ``libinput measure touchpad-size`` tool
-#. verify the hwdb entry provided by this tool
-#. test locally
-#. send a patch to the `systemd project <https://github.com/systemd/systemd>`_.
-
-Detailed explanations are below.
-
-The ``libinput measure touchpad-size`` tool is an interactive tool. It must
-be called with the physical dimensions of the touchpad in mm. In the example
-below, we use 100mm wide and 55mm high. The tool will find the touchpad device
-automatically.
-
-::
-
-     $> sudo libinput measure touchpad-size 100x55
-     Using "Touchpad SynPS/2 Synaptics TouchPad": /dev/input/event4

-     Kernel specified touchpad size: 99.7x75.9mm
-     User specified touchpad size:   100.0x55.0mm

-     Detected axis range: x [   0..   0], y [   0..   0]
-
-     Move one finger along all edges of the touchpad
-     until the detected axis range stops changing.
-
-     ...
-
-Move the finger around until the detected axis range matches the data sent
-by the device. ``Ctrl+C`` terminates the tool and prints a

-    Instructions on what to do with this snippet are in /usr/lib/udev/hwdb.d/60-evdev.hwdb
-
-
-If there are discrepancies between the coordinate range the kernels

-``60-evdev.hwdb`` file provided by the `systemd project <https://github.com/systemd/systemd>`_.
-An example commit can be found
-`here <https://github.com/systemd/systemd/commit/26f667eac1c5e89b689aa0a1daef6a80f473e045>`_.
-
-The ``libinput measure touchpad-size`` tool attempts to provide the correct
-dmi match but it does require user verification.
-
-In most cases the dmi match can and should be trimmed to the system vendor (``svn``)
-and the product version (``pvr``) or product name (``pn``), with everything else
-replaced by a wildcard (``*``). In the above case, the match string is:
-
-::
-
-     evdev:name:SynPS/2 Synaptics TouchPad:dmi:*svnLENOVO:*pvrThinkPadT440s*
-
-As a general rule: for Lenovo devices use ``pvr`` and for all others use
-``pn``.
-
-.. note:: hwdb match strings only allow for alphanumeric ascii characters. Use a
-	wildcard (* or ?, whichever appropriate) for special characters.
-
-The actual axis overrides are in the form:
-
-::
-
-     # axis number=min:max:resolution
-      EVDEV_ABS_00=2072:4880:28
-
-or, if the range is correct but the resolution is wrong
-
-::
-
-     # axis number=::resolution
-      EVDEV_ABS_00=::28
-
-
-Note the leading single space. The axis numbers are in hex and can be found
-in ``linux/input-event-codes.h``. For touchpads ``ABS_X``, ``ABS_Y``,
-``ABS_MT_POSITION_X`` and ``ABS_MT_POSITION_Y`` are required.
-
-.. note:: The touchpad's ranges and/or resolution should only be fixed when
-	there is a significant discrepancy. A few units do not make a
-	difference and a resolution that is off by 2 or less usually does
-	not matter either.
-
-Once a match and override rule has been found, follow the instructions at
-the top of the
-`60-evdev.hwdb <https://github.com/systemd/systemd/blob/main/hwdb.d/60-evdev.hwdb>`_
-file to save it locally and trigger the udev hwdb reload. Rebooting is
-always a good idea. If the match string is correct, the new properties will
-show up in the
-output of
-
-::
-
-        udevadm info /sys/class/input/event4
-
-
-Adjust the command for the event node of your touchpad.
-A udev builtin will apply the new axis ranges automatically.
-
-When the axis override is confirmed to work, please submit it as a pull
-request to the `systemd project <https://github.com/systemd/systemd>`_.

-==============================================================================
-libinput's internal architecture
-==============================================================================
-
-This page provides an outline of libinput's internal architecture. The goal
-here is to get the high-level picture across and point out the components
-and their interplay to new developers.
-
-The public facing API is in ``libinput.c``, this file is thus the entry point
-for almost all API calls. General device handling is in ``evdev.c`` with the
-device-type-specific implementations in ``evdev-<type>.c``. It is not
-necessary to understand all of libinput to contribute a patch.
-
-As of libinput 1.29 libinput has an internal plugin pipeline that modifies
-the event stream before libinput proper sees it, see
-:ref:`architecture-plugins`.
-
-:ref:`architecture-contexts` is the only user-visible implementation detail,
-everything else is purely internal implementation and may change when
-required.
-
-.. _architecture-contexts:
-
-------------------------------------------------------------------------------
-The udev and path contexts
-------------------------------------------------------------------------------
-
-The first building block is the "context" which can be one of
-two types, "path" and "udev". See **libinput_path_create_context()** and
-**libinput_udev_create_context()**. The path/udev specific bits are in
-``path-seat.c`` and ``udev-seat.c``. This includes the functions that add new
-devices to a context.
-
-
-.. graphviz::
-
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-
-      libudev [label="libudev 'add' event"]
-      udev [label="**libinput_udev_create_context()**"];
-      udev_backend [label="udev-specific backend"];
-      context [label="libinput context"]
-      udev -> udev_backend;
-      libudev -> udev_backend;
-      udev_backend -> context;
-    }
-
-
-The udev context provides automatic device hotplugging as udev's "add"
-events are handled directly by libinput. The path context requires that the
-caller adds devices.
-
-
-.. graphviz::
-
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-
-      path [label="**libinput_path_create_context()**"];
-      path_backend [label="path-specific backend"];
-      xdriver [label="**libinput_path_add_device()**"]
-      context [label="libinput context"]
-      path -> path_backend;
-      xdriver -> path_backend;
-      path_backend -> context;
-    }
-
-
-As a general rule: all Wayland compositors use a udev context, the X.org
-stack uses a path context.
-
-Which context was initialized only matters for creating/destroying a context
-and adding devices. The device handling itself is the same for both types of
-context.
-
-.. _architecture-device:
-
-------------------------------------------------------------------------------
-Device initialization
-------------------------------------------------------------------------------
-
-libinput only supports evdev devices, all the device initialization is done
-in ``evdev.c``. Much of the libinput public API is also a thin wrapper around
-the matching implementation in the evdev device.
-
-There is a 1:1 mapping between libinput devices and ``/dev/input/eventX``
-device nodes.
-
-
-
-.. graphviz::
-
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-
-      devnode [label="/dev/input/event0"]
-
-      libudev [label="libudev 'add' event"]
-      xdriver [label="**libinput_path_add_device()**"]
-      context [label="libinput context"]
-
-      evdev [label="evdev_device_create()"]
-
-      devnode -> xdriver;
-      devnode -> libudev;
-      xdriver -> context;
-      libudev -> context;
-
-      context->evdev;
-
-    }
-
-
-Entry point for all devices is ``evdev_device_create()``, this function
-decides to create a ``struct evdev_device`` for the given device node.
-Based on the udev tags (e.g. ``ID_INPUT_TOUCHPAD``), a
-:ref:`architecture-dispatch` is initialized. All event handling is then in this
-dispatch.
-
-Rejection of devices and the application of quirks is generally handled in
-``evdev.c`` as well. Common functionality shared across multiple device types
-(like button-scrolling) is also handled here.
-
-.. _architecture-dispatch:
-
-------------------------------------------------------------------------------
-Device-type specific event dispatch
-------------------------------------------------------------------------------
-
-Depending on the device type, ``evdev_configure_device`` creates the matching
-``struct evdev_dispatch``. This dispatch interface contains the function
-pointers to handle events. Four such dispatch methods are currently
-implemented: touchpad, tablet, tablet pad, and the fallback dispatch which
-handles mice, keyboards and touchscreens.
-
-.. graphviz::
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-
-      evdev [label="evdev_device_create()"]
-
-      fallback [label="evdev-fallback.c"]
-      touchpad [label="evdev-mt-touchpad.c"]
-      tablet [label="evdev-tablet.c"]
-      pad [label="evdev-tablet-pad.c"]
-
-      evdev -> fallback;
-      evdev -> touchpad;
-      evdev -> tablet;
-      evdev -> pad;
-
-    }
-
-
-Event dispatch is done per "evdev frame", a collection of events up until including
-the ``SYN_REPORT``. One such ``struct evdev_frame`` represents all state **updates**
-to the previous frame.
-
-While ``evdev.c`` pulls the event out of libevdev, the actual handling of the
-events is performed within the dispatch method.
-
-.. graphviz::
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-
-      evdev [label="evdev_device_dispatch()"]
-
-      plugins [label="plugin pipeline"]
-
-      fallback [label="fallback_interface_process()"];
-      touchpad [label="tp_interface_process()"]
-      tablet [label="tablet_process()"]
-      pad [label="pad_process()"]
-
-      evdev -> plugins;
-      plugins -> fallback;
-      plugins -> touchpad;
-      plugins -> tablet;
-      plugins -> pad;
-    }
-
-
-The dispatch methods then look at the ``struct evdev_frame`` and proceed to
-update the state.
-
-.. _architecture-plugins:
-
-------------------------------------------------------------------------------
-The Plugin Pipeline
-------------------------------------------------------------------------------
-
-As of libinput 1.29 libinput has an **internal** plugin pipeline. These plugins
-logically sit between libevdev and the :ref:`architecture-dispatch` and modify
-the device and/or event stream. The primary motivation of such plugins is that
-modifying the event stream is often simpler than analyzing the state later.
-
-Plugins are loaded on libinput context startup and are executed in-order. The last
-plugin is the hardcoded `evdev-plugin.c` which takes the modified event stream and
-passes the events to the dispatch.
-
-.. graphviz::
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-
-      evdev [label="evdev_device_dispatch()"]
-
-      p1 [label="P1"]
-      p2 [label="P2"]
-      p3 [label="P3"]
-      ep [label="evdev-plugin"]
-
-      fallback [label="fallback_interface_process()"];
-      touchpad [label="tp_interface_process()"]
-      tablet [label="tablet_process()"]
-      pad [label="pad_process()"]
-
-      evdev -> p1;
-      p1 -> p2;
-      p2 -> p3;
-      p3 -> ep;
-      ep -> fallback;
-      ep -> touchpad;
-      ep -> tablet;
-      ep -> pad;
-    }
-
-Each plugin may not only modify the current event frame (this includes adding/removing events
-from the frame), it may also append or prepend additional event frames. For
-example the tablet proximity-timer plugin adds proximity in/out events to the
-event stream.
-
-.. graphviz::
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-      n0 [label= "", shape=none,height=.0,width=.0]
-      n1 [label= "", shape=none,height=.0,width=.0]
-
-      p1 [label="P1"]
-      p2 [label="P2"]
-      p3 [label="P3"]
-      ep [label="evdev-plugin"]
-
-      n0 -> p1 [label="F1"];
-      p1 -> p2 [label="F1"];
-      p2 -> p3 [label="F1,F2"];
-      p3 -> ep [label="F3,F1,F2"];
-      ep -> n1 [label="F3,F1,F2"];
-    }
-
-In the diagram above, the plugin ``P2`` *appends* a new frame (``F2``), the plugin ``P3``
-*prepends* a new frame (``F3``). The original event frame ``F1`` thus becomes the event frame
-sequence ``F3``, ``F1``, ``F2`` by the time it reaches the :ref:`architecture-dispatch`.
-
-Note that each plugin only sees one event frame at a time, so ``P3`` would see ``F1`` first,
-decides to prepend ``F3`` and passes ``F1`` through. It then sees ``F2`` but does nothing with
-it (optionally modified in-place).
-
-.. _architecture-configuration:
-
-------------------------------------------------------------------------------
-Device configuration
-------------------------------------------------------------------------------
-
-All device-specific configuration is handled through ``struct
-libinput_device_config_FOO`` instances. These are set up during device init
-and provide the function pointers for the ``get``, ``set``, ``get_default``
-triplet of configuration queries (or more, where applicable).
-
-For example, the ``struct tablet_dispatch`` for tablet devices has a
-``struct libinput_device_config_accel``. This struct is set up with the
-required function pointers to change the profiles.
-
-
-.. graphviz::
-
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-
-      tablet [label="struct tablet_dispatch"]
-      config [label="struct libinput_device_config_accel"];
-      tablet_config [label="tablet_accel_config_set_profile()"];
-      tablet->config;
-      config->tablet_config;
-    }
-
-
-When the matching ``**libinput_device_config_set_FOO()**`` is called, this goes
-through to the config struct and invokes the function there. Thus, it is
-possible to have different configuration functions for a mouse vs a
-touchpad, even though the interface is the same.
-
-
-.. graphviz::
-
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-
-      libinput [label="**libinput_device_config_accel_set_profile()**"];
-      tablet_config [label="tablet_accel_config_set_profile()"];
-      libinput->tablet_config;
-    }
-
-
-.. _architecture-filter:
-
-------------------------------------------------------------------------------
-Pointer acceleration filters
-------------------------------------------------------------------------------
-
-All pointer acceleration is handled in the ``filter.c`` file and its
-associated files.
-
-The ``struct motion_filter`` is initialized during device init, whenever
-deltas are available they are passed to ``filter_dispatch()``. This function
-returns a set of :ref:`normalized coordinates <motion_normalization_customization>`.
-
-All actual acceleration is handled within the filter, the device itself has
-no further knowledge. Thus it is possible to have different acceleration
-filters for the same device types (e.g. the Lenovo X230 touchpad has a
-custom filter).
-
-
-.. graphviz::
-
-
-    digraph context
-    {
-      compound=true;
-      rankdir="LR";
-      node [
-        shape="box";
-      ]
-
-      fallback [label="fallback deltas"];
-      touchpad [label="touchpad deltas"];
-      tablet [label="tablet deltas"];
-
-      filter [label="filter_dispatch"];
-
-      fallback->filter;
-      touchpad->filter;
-      tablet->filter;
-
-      flat [label="accelerator_interface_flat()"];
-      x230 [label="accelerator_filter_x230()"];
-      pen [label="tablet_accelerator_filter_flat_pen()"];
-
-      filter->flat;
-      filter->x230;
-      filter->pen;
-
-    }
-
-
-Most filters convert the deltas (incl. timestamps) to a motion speed and
-then apply a so-called profile function. This function returns a factor that
-is then applied to the current delta, converting it into an accelerated
-delta. See :ref:`pointer-acceleration` for more details.

-Distribution repositories for libinput from git
-------------------------------------------------------------------------------
-
-Some distributions provide package repositories for users that want to test
-the latest libinput without building it manually.
-
-.. note:: The list below is provided for convenience. The libinput community
-   cannot provide any guarantees that the packages in those repositories are
-   correct, up-to-date and/or unmodified from the git branch. Due diligence
-   is recommended.
-
-The following repositories provide an up-to-date package for libinput:
-
-- **Arch:** https://aur.archlinux.org/packages/libinput-git/
-- **Fedora:** https://copr.fedorainfracloud.org/coprs/whot/libinput-git/
-
-Please follow the respective repositories for instructions on how to enable
-the repository and install libinput.
-
-
-.. _building:
-
-------------------------------------------------------------------------------
-Building libinput
-------------------------------------------------------------------------------
-
-libinput uses `meson <https://www.mesonbuild.com>`_ and
-`ninja <https://www.ninja-build.org>`_. A build is usually the three-step
-process below.  A successful build requires the
-:ref:`building_dependencies` to be installed before running meson.
-
-
-::
-
-     $> git clone https://gitlab.freedesktop.org/libinput/libinput
-     $> cd libinput
-     $> meson setup --prefix=/usr builddir/
-     $> ninja -C builddir/
-     $> sudo ninja -C builddir/ install
-
-
-When running libinput versions 1.11.x or earlier, you must run
-
-::
-
-     $> sudo systemd-hwdb update
-
-
-Additional options may also be specified. For example:
-
-::
-
-     $> meson setup --prefix=/usr -Ddocumentation=false builddir/
-
-
-We recommend that users disable the documentation, it's not usually required
-for testing and reduces the number of dependencies needed.
-
-The ``prefix`` or other options can be changed later with the
-``meson configure`` command. For example:
-
-::
-
-     $> meson configure builddir/ -Dprefix=/some/other/prefix -Ddocumentation=true
-     $> ninja -C builddir
-     $> sudo ninja -C builddir/ install
-
-
-Running ``meson configure builddir/`` with no other arguments lists all
-configurable options meson provides.
-
-To rebuild from scratch, simply remove the build directory and run meson
-again:
-
-::
-
-     $> rm -r builddir/
-     $> meson setup --prefix=....
-
-
-.. _verifying_install:
-
-..............................................................................
-Verifying the install
-..............................................................................
-
-To verify the install worked correctly, check that libinput.so.x.x.x is in
-the library path and that all symlinks point to the new library.
-
-::
-
-     $> ldconfig -p | grep libinput | awk '{print $NF}' | xargs ls -l
-     lrwxrwxrwx 1 root root      14 lug 22 13:06 /usr/lib/x86_64-linux-gnu/libinput.so -> libinput.so.10
-     lrwxrwxrwx 1 root root      19 lug 22 13:06 /usr/lib/x86_64-linux-gnu/libinput.so.10 -> libinput.so.10.13.0
-     -rwxr-xr-x 1 root root 1064144 lug 22 13:06 /usr/lib/x86_64-linux-gnu/libinput.so.10.13.0
-
-.. _reverting_install:
-
-..............................................................................
-Reverting to the system-provided libinput package
-..............................................................................
-
-The recommended way to revert to the system install is to use the package
-manager to reinstall the libinput package. In some cases, this may leave
-files in the system (e.g. ``/usr/lib/libinput.la``) but these files are
-usually harmless. To definitely remove all files, run the following command
-from the libinput source directory:
-
-
-::
-
-     $> sudo ninja -C builddir/ uninstall
-     # WARNING: Do not restart the computer/X/the Wayland compositor after
-     # uninstall, reinstall the system package immediately!
-
-
-The following commands reinstall the current system package for libinput,
-overwriting manually installed files.
-
-- **Debian/Ubuntu** based distributions: ``sudo apt-get install --reinstall libinput``
-- **Fedora 22** and later: ``sudo dnf reinstall libinput``
-- **RHEL/CentOS/Fedora 21** and earlier: ``sudo yum reinstall libinput``
-- **openSUSE**: ``sudo zypper install --force libinput10``
-- **Arch**: ``sudo pacman -S libinput``

-.. _building_selinux:
-
-..............................................................................
-SELinux adjustments
-..............................................................................
-
-.. note:: This section only applies to meson version < 0.42.0
-
-On systems with SELinux, overwriting the distribution-provided package with
-a manually built libinput may cause SELinux denials. This usually manifests
-when gdm does not start because it is denied access to libinput. The journal
-shows a log message in the form of:
-
-
-::
-
-     May 25 15:28:42 localhost.localdomain audit[23268]: AVC avc:  denied  { execute } for  pid=23268 comm="gnome-shell" path="/usr/lib64/libinput.so.10.12.2" dev="dm-0" ino=1709093 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:user_home_t:s0 tclass=file permissive=0
-     May 25 15:28:42 localhost.localdomain org.gnome.Shell.desktop[23270]: /usr/bin/gnome-shell: error while loading shared libraries: libinput.so.10: failed to map segment from shared object
-
-
-The summary of this error message is that gdm's gnome-shell runs in the
-``system_u:system_r:xdm_t`` context but libinput is installed with the
-context ``unconfined_u:object_r:user_home_t``.
-
-To avoid this issue, restore the SELinux context for any system files.
-
-
-::
-
-     $> sudo restorecon /usr/lib*/libinput.so.*
-
-
-This issue is tracked in https://github.com/mesonbuild/meson/issues/1967.
-
-.. _building_dependencies:
-
-------------------------------------------------------------------------------
-Build dependencies
-------------------------------------------------------------------------------
-
-libinput has a few build-time dependencies that must be installed prior to
-running meson.
-
-.. hint:: The build dependencies for some distributions can be found in the
-	`GitLab Continuous Integration file <https://gitlab.freedesktop.org/libinput/libinput/blob/main/.gitlab-ci.yml>`_.
-	Search for **FEDORA_PACKAGES** in the **variables:** definition
-	and check the list for an entry for your distribution.
-
-In most cases, it is sufficient to install the dependencies that your
-distribution uses to build the libinput package.  These can be installed
-with one of the following commands:
-
-- **Debian/Ubuntu** based distributions: ``sudo apt-get build-dep libinput``
-- **Fedora 22** and later: ``sudo dnf builddep libinput``
-- **RHEL/CentOS/Fedora 21** and earlier: ``sudo yum-builddep libinput``
-- **openSUSE**: ::
-
-     $> sudo zypper modifyrepo --enable ``zypper repos | grep source | awk '{print $5}'``
-     $> sudo zypper source-install -d libinput10
-     $> sudo zypper install autoconf automake libtool
-     $> sudo zypper modifyrepo --disable ``zypper repos | grep source | awk '{print $5}'``
-
-
-- **Arch**: ::
-
-     $> sudo pacman -S asp
-     $> cd $(mktemp -d)
-     $> asp export libinput
-     $> cd libinput
-     $> makepkg --syncdeps --nobuild --noextract
-
-
-
-If dependencies are missing, meson shows a message ``No package 'foo'
-found``.  See
-`this blog post here <https://who-t.blogspot.com/2018/07/meson-fails-with-native-dependency-not-found.html>`_

-
-------------------------------------------------------------------------------
-Conditional builds
-------------------------------------------------------------------------------
-
-libinput supports several meson options to disable parts of the build. See
-the ``meson_options.txt`` file in the source tree for a full list of
-available options. The default build enables most options and thus requires
-more build dependencies. On systems where build dependencies are an issue,
-options may be disabled with this meson command: ::
-
-    meson setup --prefix=/usr -Dsomefeature=false builddir
-
-Where ``-Dsomefeature=false`` may be one of:
-
-- ``-Ddocumentation=false``
-    Disables the documentation build (this website). Building the
-    documentation is only needed on the maintainer machine.
-- ``-Dtests=false``
-    Disables the test suite. The test suite is only needed on developer
-    systems.
-- ``-Ddebug-gui=false``
-    Disables the ``libinput debug-gui`` helper tool (see :ref:`tools`),
-    dropping GTK and other build dependencies. The debug-gui is only
-    required for troubleshooting.
-- ``-Dlibwacom=false``
-    libwacom is required by libinput's tablet code to gather additional
-    information about tablets that is not available from the kernel device.
-    It is not recommended to disable libwacom unless libinput is used in an
-    environment where tablet support is not required. libinput provides tablet
-    support even without libwacom, but some features may be missing or working
-    differently.
-
-.. _building_against:
-
-------------------------------------------------------------------------------
-Building against libinput
-------------------------------------------------------------------------------
-
-libinput provides a
-`pkg-config <https://www.freedesktop.org/wiki/Software/pkg-config/>`_ file.
-Software that uses autotools should use the ``PKG_CHECK_MODULES`` autoconf
-macro: ::
-
-    PKG_CHECK_MODULES(LIBINPUT, "libinput")
-
-Software that uses meson should use the ``dependency()`` function: ::
-
-    pkgconfig = import('pkgconfig')
-    dep_libinput = dependency('libinput')
-
-Software that uses CMake should use: ::
-
-    find_package(Libinput)
-    target_link_libraries(myprogram PRIVATE Libinput::Libinput)
-
-Otherwise, the most rudimentary way to compile and link a program against
-libinput is:
-
-
-::
-
-         gcc -o myprogram myprogram.c ``pkg-config --cflags --libs libinput``
-
-
-For further information on using pkgconfig see the pkg-config documentation.

-
-==============================================================================
-Button debouncing
-==============================================================================
-
-Physical buttons experience wear-and-tear with usage. On some devices this
-can result in an effect called "contact bouncing" or "chatter". This effect
-can cause the button to send multiple events within a short time frame, even
-though the user only pressed or clicked the button once. This effect can be
-counteracted by "debouncing" the buttons, usually by ignoring erroneous
-events.
-
-libinput provides two methods of debouncing buttons, referred to as the
-"bounce" and "spurious" methods:
-
-- In the "bounce" method, libinput monitors hardware bouncing on button
-  state changes, i.e. when a user clicks or releases a button. For example,
-  if a user presses a button but the hardware generates a
-  press-release-press sequence in quick succession, libinput ignores the
-  release and second press event. This method is always enabled.
-- in the "spurious" method, libinput detects spurious releases of a button
-  while the button is physically held down by the user. These releases are
-  immediately followed by a press event. libinput monitors for these events
-  and ignores the release and press event. This method is disabled by
-  default and enables once libinput detects the first faulty event sequence.
-
-The "bounce" method guarantees that all press events are delivered
-immediately and most release events are delivered immediately. The
-"spurious" method requires that release events are delayed, libinput thus
-does not enable this method unless a faulty event sequence is detected. A
-message is printed to the log when spurious debouncing was detected.
-
-libinput's debouncing is supposed to correct hardware damage or
-substandard hardware. Debouncing also exists as an accessibility feature
-but the requirements are different. In the accessibility feature, multiple
-physical key presses, usually caused by involuntary muscle movement, must be
-filtered to only one key press. This feature must be implemented higher in
-the stack, libinput is limited to hardware debouncing.
-
-Below is an illustration of the button debouncing modes to show the relation
-of the physical button state and the application state. Where applicable, an
-extra line is added to show the timeouts used by libinput that
-affect the button state handling. The waveform's high and low states
-correspond to the buttons 'pressed' and 'released' states, respectively.
-
-.. figure:: button-debouncing-wave-diagram.svg
-    :align: center
-
-    Diagram illustrating button debouncing

-Some devices send events in bursts, erroneously triggering the button
-debouncing detection. Please :ref:`file a bug <reporting_bugs>` if that
-occurs for your device.

-Clickpad software button behavior
-==============================================================================
-
-"Clickpads" are touchpads without separate physical buttons. Instead, the
-whole touchpad acts as a button and left or right button clicks are
-distinguished by :ref:`the location of the fingers <software_buttons>` or
-the :ref:`number of fingers on the touchpad <clickfinger>`.
-"ClickPad" is a trademark by `Synaptics Inc. <http://www.synaptics.com/en/clickpad.php>`_
-but for simplicity we refer to any touchpad with the above feature as Clickpad,
-regardless of the manufacturer.
-
-The kernel marks clickpads with the
-`INPUT_PROP_BUTTONPAD <https://www.kernel.org/doc/Documentation/input/event-codes.txt>`_
-property. Without this property, libinput would not know whether a touchpad
-is a clickpad or not. To perform a right-click on a Clickpad, libinput
-provides :ref:`software_buttons` and :ref:`clickfinger`.
-
-.. note:: The term "click" refers refer to a physical button press
-	  and/or release of the touchpad, the term "button event" refers to
-	  the events generated by libinput in response to a click.
-
-.. _software_buttons:
-
-------------------------------------------------------------------------------
-Software button areas
-------------------------------------------------------------------------------
-
-The bottom of the touchpad is split into three distinct areas generate left,
-middle or right button events on click. The height of the button area
-depends on the hardware but is usually around 10mm.
-
-.. figure :: software-buttons-visualized.svg
-     :align: center
-
-     The locations of the virtual button areas.
-
-
-Left, right and middle button events can be triggered as follows:
-
-- if a finger is in the main area or the left button area, a click generates
-  left button events.
-- if a finger is in the right area, a click generates right button events.
-- if a finger is in the middle area, a click generates middle button events.
-
-.. figure:: software-buttons.svg
-    :align: center
-
-    Left, right and middle-button click with software button areas
-
-The middle button is always centered on the touchpad and smaller in size
-than the left or right button. The actual size is device-dependent. Many
-touchpads do not have visible markings so the exact location of the button
-is unfortunately not visibly obvious.
-
-.. note:: If :ref:`middle button emulation <middle_button_emulation>` is
-	  enabled on a clickpad, only left and right button areas are
-	  available.
-
-If fingers are down in the main area in addition to fingers in the
-left or right button area, those fingers are are ignored.
-A release event always releases the buttons logically down, regardless of
-the current finger position
-
-.. figure:: software-buttons-thumbpress.svg
-    :align: center
-
-    Only the location of the thumb determines whether it is a left, right or
-    middle click.
-
-The movement of a finger can alter the button area behavior:
-
-- if a finger starts in the main area and moves into the software button
-  area, the software buttons do not apply to that finger
-- once a finger has moved out of the button area, it cannot move back in and
-  trigger a right or middle button event
-- a finger moving within the software button area does not move the pointer
-- once a finger moves out out of the button area it will control the
-  pointer (this only applies if there is no other finger down on the
-  touchpad)
-
-.. figure:: software-buttons-conditions.svg
-    :align: center
-
-    **Left:** moving a finger into the right button area does not trigger a
-    right-button click.
-    **Right:** moving within the button areas does not generate pointer
-    motion.
-
-On some touchpads, notably the 2015 Lenovo X1 Carbon 3rd series, the very
-bottom end of the touchpad is outside of the sensor range but it is possible
-to trigger a physical click there. To libinput, the click merely shows up as
-a left button click without any positional finger data and it is
-impossible to determine whether it is a left or a right click. libinput
-ignores such button clicks, this behavior is intentional.
-
-.. _clickfinger:
-
-------------------------------------------------------------------------------
-Clickfinger behavior
-------------------------------------------------------------------------------
-
-This is the default behavior on Apple touchpads. Here, a left, right, middle
-button event is generated when one, two, or three fingers are held down on the
-touchpad when a physical click is generated, given the default mapping. The
-location of the fingers does not matter and there are no software-defined
-button areas. It is possible to swap right and middle buttons, the same way as
-with :ref:`tapping <tapping>`.
-
-.. figure:: clickfinger.svg
-    :align: center
-
-    One, two and three-finger click with Clickfinger behavior
-
-On some touchpads, libinput imposes a limit on how the fingers may be placed
-on the touchpad. In the most common use-case this allows for a user to
-trigger a click with the thumb while leaving the pointer-moving finger on
-the touchpad.
-
-.. figure:: clickfinger-distance.svg
-    :align: center
-
-    Illustration of the distance detection algorithm
-
-In the illustration above the red area marks the proximity area around the

-click a single-finger click rather than a two-finger click.
-
-.. _special_clickpads:

-The Lenovo \*40 series laptops have a clickpad that provides two software button sections, one at
-the top and one at the bottom. See :ref:`Lenovo \*40 series touchpad support <t440_support>`
-for details on the top software button.
-
-Some Clickpads, notably some Cypress ones, perform right button detection in
-firmware and appear to userspace as if the touchpad had physical buttons.
-While physically clickpads, these are not handled by the software and

-.. _clickpads_with_right_buttons:
-
-==============================================================================
-Clickpads with a fake right button
-==============================================================================
-
-libinput relies on the kernel to label :ref:`Clickpads <touchpads_buttons_clickpads>`
-with the ``INPUT_PROP_BUTTONPAD`` property so it can enable the correct
-:ref:`clickpad_softbuttons`. Clickpads are not expected to have a right button
-since the whole surface can be depressed.
-
-A common bug encountered with :ref:`Clickpads <touchpads_buttons_clickpads>`
-is that the device advertises a physical right button where no such button
-exists. This is usually a bug in the firmware of the device and causes the
-following warning to be emitted by libinput::
-
-    "<device name> clickpad advertising right button"
-
-The user-visible effect of this is usually negligible since these devices
-cannot actually trigger a right click and libinput's default behaviors for
-clickpads work as expected.
-
-However, we should nonetheless correct the device to get rid of this warning
-and avoid potential issues with future features. The :ref:`device-quirks`
-provide a simple way to disable the fake right button on the device. The
-following quirk disables the right button on the MyModel laptop from the
-MyVendor OEM::
-
-    [MyVendor MyModel Touchpad]
-    MatchName=Foo Bar Touchpad
-    MatchUdevtype=touchpad
-    MatchDMIModAlias=dmi:*:svnMyVendor:pnMyModel:*
-    AttrEventCode=-BTN_RIGHT
-
-The name of the device can be obtained using :ref:`libinput record <libinput-record>`,
-the modalias match is a shell-style glob against the value of ``/sys/class/dmi/id/modalias``.
-In most cases, matching should be against ``svn`` (system vendor) and one of
-``pn`` (product name) or ``pvr`` (product version), whichever provides a
-useful description of the individual laptop model. See the
-:ref:`device-quirks` documentation for details on testing local quirks.
-
-For reference, some example commits that add such a quirk are:

-Configuration options
-==============================================================================
-
-Below is a list of configurable options exposed to the users.
-
-.. contents::
-   :depth: 1
-   :local:
-
-
-.. hint:: Not all configuration options are available on all devices. Use
-	  :ref:`libinput list-devices <libinput-list-devices>` to show the
-	  configuration options for local devices.
-
-libinput's configuration interface is available to the caller only, not
-directly to the user. Thus it is the responsibility of the caller to expose
-the various options and how these options are exposed. For example, the
-`xf86-input-libinput driver <https://gitlab.freedesktop.org/xorg/driver/xf86-input-libinput/>`_
-exposes the options through X Input device properties and `xorg.conf.d
-<https://linux.die.net/man/5/xorg.conf.d>`_ options.  See the `libinput(4)
-<https://www.mankier.com/4/libinput>`_ man page for more details.
-
-
-------------------------------------------------------------------------------
-Tap-to-click
-------------------------------------------------------------------------------
-
-See :ref:`tapping` for details on how this feature works. Configuration
-options exposed by libinput are:
-
-- how many tapping fingers are supported by this device
-- a toggle to enable/disable tapping
-- a toggle to enable/disable tap-and-drag, see :ref:`tapndrag`.
-- a toggle to enable/disable tap-and-drag drag lock, see :ref:`tapndrag`
-- The default order is 1, 2, 3 finger tap mapping to left, right, middle
-  click, respectively. This order can be changed to left, middle, right click,
-  respectively.
-
-Tapping is usually available on touchpads and the touchpad part of external
-graphics tablets. Tapping is usually **not** available on touch screens,
-for those devices it is expected to be implemented by the toolkit.
-
-------------------------------------------------------------------------------
-Three-finger drag
-------------------------------------------------------------------------------
-
-Three-finger drag emulates the mouse button down while three fingers
-are down on a touchpad without the need to press a physical button or use
-:ref:`tapndrag`. See :ref:`drag_3fg` for details on how this feature works.
-
-Three-finger drag is usually available on touchpads and the touchpad part of
-external graphics tablets. Three-finger drag is usually **not** available on
-touch screens, for those devices it is expected to be implemented by the
-toolkit.
-
-------------------------------------------------------------------------------
-Send Events Mode
-------------------------------------------------------------------------------
-
-The Send Events Mode is libinput's terminology for disabling a device. It is
-more precise in that the device only stops sending events but may not get
-fully disabled. For example, disabling the touchpad on a
-:ref:`Lenovo T440 and similar <t440_support>` leaves the top software
-buttons enabled for the trackpoint. Available options are
-**enabled** (send events normally), **disabled** ( do not send events),
-**disabled on external mouse** (disable the device while an external mouse
-is plugged in).
-
-
-.. _config_pointer_acceleration:
-
-------------------------------------------------------------------------------
-Pointer acceleration
-------------------------------------------------------------------------------
-
-Pointer acceleration is a function to convert input deltas to output deltas,
-usually based on the movement speed of the device, see
-:ref:`pointer-acceleration` for details.
-
-Pointer acceleration is normalized into a [-1, 1] range, where -1 is
-"slowest" and 1 is "fastest". Most devices use a default speed of 0.
-
-The pointer acceleration profile defines **how** the input deltas are
-converted, see :ref:`ptraccel-profiles`. Most devices have their default
-profile (usually called "adaptive") and a "flat" profile. The flat profile
-does not apply any acceleration.
-
-------------------------------------------------------------------------------
-Scrolling
-------------------------------------------------------------------------------
-
-"Natural scrolling" is the terminology for moving the content in the
-direction of scrolling, i.e. moving the wheel or fingers down moves the page
-down. Traditional scrolling moves the content in the opposite direction.
-Natural scrolling can be turned on or off, it is usually off by default.
-
-The scroll method defines how to trigger scroll events. On touchpads
-libinput provides two-finger scrolling and edge scrolling. Two-finger
-scrolling converts a movement with two fingers to a series of scroll events.
-Edge scrolling converts a movement with one finger along the right or bottom
-edge of the touchpad into a series of scroll events.
-
-On other libinput provides button-scrolling - movement of the device while
-the designated scroll button is down is converted to scroll events. The
-button used for scrolling is configurable.
-
-The scroll method can be chosen or disabled altogether but most devices only
-support a subset of available scroll methods. libinput's default is
-two-finger scrolling for multi-touch touchpads, edge scrolling for
-single-touch touchpads. On tracksticks, button scrolling is enabled by
-default.
-
-See :ref:`scrolling` for more details on how the scroll methods work.
-
-------------------------------------------------------------------------------
-Left-handed Mode
-------------------------------------------------------------------------------
-
-Left-handed mode switches the device's functionality to be more
-accommodating for left-handed users. On mice this usually means swapping the
-left and right mouse button, on tablets this allows the tablet to be used
-upside-down to present the pad buttons for the non-dominant right hand. Not
-all devices have left-handed mode.
-
-Left-handed mode can be enabled or disabled and is disabled by default.
-
-------------------------------------------------------------------------------
-Middle Button Emulation
-------------------------------------------------------------------------------
-
-Middle button emulation converts a simultaneous left and right button click
-into a middle button. The emulation can be enabled or disabled. Middle
-button emulation is usually enabled when the device does not provide a
-middle button.
-
-------------------------------------------------------------------------------
-Click method
-------------------------------------------------------------------------------
-
-The click method defines how button events are triggered on a :ref:`clickpad
-<clickpad_softbuttons>`. When set to button areas, the bottom area of the
-touchpad is divided into a left, middle and right button area. When set to
-clickfinger, the number of fingers on the touchpad decide the button type.
-Clicking with 1, 2, 3 fingers triggers a left, right, or middle click,
-respectively. The default click method is software button areas. Click
-methods are usually only available on :ref:`clickpads
-<clickpad_softbuttons>`.
-
-------------------------------------------------------------------------------
-Disable while typing
-------------------------------------------------------------------------------
-
-DWT is the most generic form of palm detection on touchpad. While the user
-is typing on an internal keyboard the touchpad is disabled, the touchpad
-is enabled again after a timeout.  See :ref:`disable-while-typing` for more
-info.
-
-Disable-while-typing can be enabled or disabled, it is enabled by default on
-most touchpads.
-
-------------------------------------------------------------------------------
-Disable while trackpointing
-------------------------------------------------------------------------------
-
-DWTP is a form of palm detection for devices that have a trackpoint (like
-Thinkpads). While the user is using the trackpoint, the touchpad is disabled,
-being enabled again after a timeout. See :ref:`disable-while-trackpointing` for
-more info.
-
-Disable-while-trackpointing can be enabled or disabled, it is enabled by
-default.
-
-------------------------------------------------------------------------------
-Calibration
-------------------------------------------------------------------------------
-
-Calibration is available for some direct-input devices (touch screens,
-graphics tablets, etc.). The purpose of calibration is to ensure the input
-lines up with the output and the configuration data is a transformation
-matrix. It is thus not expected that the user sets this option. The desktop
-environment should provide an interface for this.
-
-------------------------------------------------------------------------------
-Rotation
-------------------------------------------------------------------------------
-
-The device rotation applies a corrective angle to relative input events,
-allowing the device to be used e.g. sideways or upside-down. For example, a
-trackball may be used in a 90° rotated position for accessibility reasons -
-such a rotated position allows triggering the buttons with the thumb or
-the non-dominant hand.
-
-Note that where a device rotation is higher than 160 but less than 200 degrees,
-the direction of wheels is also inverted. For all other angles, the wheel
-direction is left as-is.
-
-.. _config-tablet-pressure-range:
-
-------------------------------------------------------------------------------
-Tablet tool pressure range
-------------------------------------------------------------------------------
-
-The pressure range on a :ref:`Tablet tool <tablet-tools>` can be reduced
-from the full available hardware range to a subset of that range. The effect
-of this is that the tablet will not register pressure below the given
-the given threshold is met, and will reach the maximum logical pressure
-before the maximum hardware-supported pressure is reached.
-
-See :ref:`tablet-pressure-range` for more info.
-
-.. _config-tablet-eraser-buttons:
-
-------------------------------------------------------------------------------
-Tablet tool eraser buttons
-------------------------------------------------------------------------------
-
-On many contemporary :ref:`Tablet tools <tablet-tools>` one button is hardcoded
-in firmware to emulate an eraser. This button can be remapped to provide
-a normal stylus button instead.
-
-See :ref:`tablet-eraser-button` for more info.
-
-------------------------------------------------------------------------------
-Area configuration
-------------------------------------------------------------------------------
-
-Area configuration is available for some indirect input devices such as
-graphics tablets. This configuration allows reducing the active area of
-such a device to a subset of the physically possible area.
-
-An example use-case for this is to match the aspect ratio of the device to that
-of the screen.
-
-See :ref:`tablet-area` for more info.

-Code of Conduct
-------------------------------------------------------------------------------
-
-As a freedesktop.org project, libinput follows the `freedesktop.org
-Contributor Covenant <https://www.freedesktop.org/wiki/CodeOfConduct>`_.
-
-Please conduct yourself in a respectful and civilised manner when
-interacting with community members on mailing lists, IRC, or bug trackers.
-The community represents the project as a whole, and abusive or bullying
-behaviour is not tolerated by the project.
-
-------------------------------------------------------------------------------
-Contact
-------------------------------------------------------------------------------
-
-Questions can be asked on ``#wayland`` on oftc or on the
-`wayland-devel@lists.freedesktop.org
-<https://lists.freedesktop.org/mailman/listinfo/wayland-devel>`_ mailing
-list.
-
-For IRC, ping user ``whot`` (Peter Hutterer, the libinput maintainer) though
-note that he lives on UTC+10 and thus the rest of the world is out of sync
-by default ;)
-
-For anything that appears to be device specific and/or related to a new
-feature, just file `an issue in our issue tracker
-<https://gitlab.freedesktop.org/libinput/libinput/issues>`_. It's usually the
-most efficient way to get answers.
-
-------------------------------------------------------------------------------
-What to work on?
-------------------------------------------------------------------------------
-
-If you don't already know what you want to improve or fix with libinput,
-then a good way of finding something is to search for the ``help needed``
-tag in our `issue tracker <https://gitlab.freedesktop.org/libinput/libinput/issues?label_name%5B%5D=help+needed>`_.
-These are issues that have been triaged to some degree and deemed to be a
-possible future feature to libinput.
-
-.. note:: Some of these issue may require specific hardware to reproduce.
-
-Another good place to help out with is the documentation. For anything you
-find in these pages that isn't clear enough please feel free to reword it
-and add what is missing.
-
-------------------------------------------------------------------------------
-Getting the code
-------------------------------------------------------------------------------
-
-The :ref:`building_libinput` have all the details but the short solution
-will be:
-
-::
-
-     $> git clone https://gitlab.freedesktop.org/libinput/libinput
-     $> cd libinput
-     $> meson setup --prefix=/usr builddir/
-     $> ninja -C builddir/
-     $> sudo ninja -C builddir/ install
-
-You can omit the last step if you only want to test locally.
-
-------------------------------------------------------------------------------
-Working on the code
-------------------------------------------------------------------------------
-
-If you are planning to send patches, it's a good idea to set up
-`pre-commit <https://pre-commit.com/>`_ with these commands::
-
-     $> pre-commit install
-     $> pre-commit install --hook-type pre-push
-
-This will check a few things before you commit and/or push to your repos to
-reduce the turnaround time for some common mistakes.
-
-libinput has a roughly three-parts architecture:
-
--  the front-end code which handles the ``libinput_some_function()`` API calls in ``libinput.c``
--  the generic evdev interface handling which maps those API calls to the
-   backend calls (``evdev.c``).
-- there are device-specific backends which do most of the actual work -
-  ``evdev-mt-touchpad.c`` is the one for touchpads for example.
-
-In general, things that only affect the internal workings of a device only
-get implemented in the device-specific backend. You only need to touch the
-API when you are adding configuration options. For more details, please read
-the :ref:`architecture` document. There's also a `blog post describing the
-building blocks
-<https://who-t.blogspot.com/2019/03/libinputs-internal-building-blocks.html>`_
-that may help to understand how it all fits together.
-
-Documentation is in ``/doc/api`` for the doxygen-generated API documentation.
-These are extracted from the libinput source code directly. The
-documentation you're reading right now is in ``/doc/user`` and generated with
-sphinx. Simply running ``ninja -C builddir`` will rebuild it and the final
-product ends up in ``builddir/Documentation``.
-
-------------------------------------------------------------------------------
-Testing the code
-------------------------------------------------------------------------------
-
-libinput provides a bunch of :ref:`tools` to debug any changes - without
-having to install libinput.
-
-The two most useful ones are :ref:`libinput debug-events
-<libinput-debug-events>` and :ref:`libinput debug-gui <libinput-debug-gui>`.
-Both tools can be run from the build directory directly and are great for
-quick test iterations::
-
-  $> sudo ./builddir/libinput-debug-events --verbose
-  $> sudo ./builddir/libinput-debug-gui --verbose
-
-The former provides purely textual output and is useful for verifying event
-streams from buttons, etc. The latter is particularly useful when you are
-trying to debug pointer movement or placement. ``libinput debug-gui`` will
-also visualize the raw data from the device so you can compare pointer
-behavior with what comes from the kernel.
-
-These tools create a new libinput context and will not affect your session's
-behavior. Only once you've installed libinput and restarted your session
-will your changes affect the X server/Wayland compositor.
-
-Once everything seems to be correct, it's time to run the
-:ref:`test-suite`::
-
-  $> sudo ./builddir/libinput-test-suite
-
-This test suite can take test names etc. as arguments, have a look at
-:ref:`test-suite` for more info. There are a bunch of other tests that are
-run by the CI on merge requests, you can run those locally with ::
-
-  $> sudo ninja -C builddir check
-
-So it always pays to run that before submitting. This will also run the code
-through valgrind and pick up any memory leaks.
-
-.. _contributing_submitting_code:
-
-------------------------------------------------------------------------------
-Submitting Code
-------------------------------------------------------------------------------
-
-Any patches should be sent via a Merge Request (see the `GitLab docs
-<https://docs.gitlab.com/ce/gitlab-basics/add-merge-request.htm>`_)
-in the `libinput GitLab instance hosted by freedesktop.org
-<https://gitlab.freedesktop.org/libinput/libinput>`_.
-
-.. note:: freedesktop.org's GitLab instance has restrictions to prevent Spam
-          and you cannot fork libinput until you have successfully
-          `applied for fork permissions <https://gitlab.freedesktop.org/freedesktop/freedesktop/-/wikis/home>`_.
-
-Below are the steps required to submit a merge request. They do not
-replace `learning git <https://git-scm.com/doc>`__ but they should be
-sufficient to make some of the more confusing steps obvious.
-
-- `Register an account <https://gitlab.freedesktop.org/users/sign_in>`_ in
-  the freedesktop.org GitLab instance and
-  `apply for fork permissions <https://gitlab.freedesktop.org/freedesktop/freedesktop/-/wikis/home>`_.
-- `Fork libinput <https://gitlab.freedesktop.org/libinput/libinput/-/forks/new>`_
-  into your username's namespace. Select public visibility.
-- Get libinput's main repository. git will call this repository ``origin``. ::
-
-    git clone https://gitlab.freedesktop.org/libinput/libinput.git
-
-- Add the forked git repository to your remotes (replace ``USERNAME``
-  with your username). git will call this repository ``gitlab``. ::
-
-    cd /path/to/libinput.git
-    git remote add gitlab git@ssh.gitlab.freedesktop.org:USERNAME/libinput.git
-    git fetch gitlab
-
-- Create a new branch and commit your changes to that branch. ::
-
-    git switch -C mynewbranch
-    # edit files, make changes
-    git add file1 file2
-    git commit -s
-    # edit commit message in the editor
-
-  Replace ``mynewbranch`` (here and in the commands below) with a meaningful
-  name. See :ref:`contributing_commit_messages` for details on the commit
-  message format.
-
-- Push your changes to your fork and submit a merge request ::
-
-    git push gitlab mynewbranch
-
-  This command will print the URL to file a merge request, you then only
-  have to click through. Alternatively you can go to:
-
-    https://gitlab.freedesktop.org/USERNAME/libinput/merge_requests
-
-  Select your branch name to merge and ``libinput/libinput`` ``main`` as target branch.
-
-- Verify that the CI completes successfully by visiting the merge request
-  page. A successful pipeline shows only green ticks, failure is indicated
-  by a red cross or a yellow exclamation mark (see
-  the `GitLab Docs
-  <https://docs.gitlab.com/ee/ci/pipelines/#pipeline-mini-graphs>`__). For
-  details about the failures, click on the failed jobs in the pipelines
-  and/or click the ``Expand`` button in the box for the test summaries.
-
-  A merge request without a successful pipeline may never be looked at by a
-  maintainer.
-
-- If changes are requested by the maintainers, please **amend** the
-  commit(s) and **force-push** the updated branch. ::
-
-    # edits in file foo.c
-    git add foo.c
-    git commit --amend
-    git push -f gitlab mynewbranch
-
-  A force-push will re-trigger the CI and notify the merge request that new
-  changes are available.
-
-  If the branch contains more than one commit, please look at
-  `git interactive rebases
-  <https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History>`__
-  to learn how to change multiple commits, or squash new changes into older
-  commits.
-
-------------------------------------------------------------------------------
-Commit History
-------------------------------------------------------------------------------
-
-libinput strives to have a
-`linear, 'recipe' style history <http://www.bitsnbites.eu/git-history-work-log-vs-recipe/>`_
-This means that every commit should be small, digestible, stand-alone, and
-functional. Rather than a purely chronological commit history like this: ::
-
-	doc: final docs for view transforms
-	fix tests when disabled, redo broken doc formatting
-	better transformed-view iteration (thanks Hannah!)
-	try to catch more cases in tests
-	tests: add new spline test
-	fix compilation on splines
-	doc: notes on reticulating splines
-	compositor: add spline reticulation for view transforms
-
-We aim to have a clean history which only reflects the final state, broken up
-into functional groupings: ::
-
-	compositor: add spline reticulation for view transforms
-	compositor: new iterator for view transforms
-	tests: add view-transform correctness tests
-	doc: fix Doxygen formatting for view transforms
-
-This ensures that the final patch series only contains the final state,
-without the changes and missteps taken along the development process.
-
-The first line of a commit message should contain a prefix indicating
-what part is affected by the patch followed by one sentence that
-describes the change. For example: ::
-
-	touchpad: add software button behavior
-	fallback: disable button debouncing on device foo
-
-If in doubt what prefix to use, look at other commits that change the
-same file(s) as the patch being sent.
-
-.. _contributing_commit_messages:
-
-------------------------------------------------------------------------------
-Commit Messages
-------------------------------------------------------------------------------
-
-When you re-send patches, revised or not, it would be very good to document the
-changes compared to the previous revision in the commit message and/or the
-merge request. If you have already received Reviewed-by or Acked-by tags, you
-should evaluate whether they still apply and include them in the respective
-commit messages. Otherwise the tags may be lost, reviewers miss the credit they
-deserve, and the patches may cause redundant review effort.
-
-If your commit solves a GitLab issue, add a ``Closes:`` tag followed by the
-issue number at the end of your commit message. For example: ::
-
-  Closes: #974
-
-If your commit fixes an issue introduced by another commit, use a ``Fixes`` tag
-followed by the first 12 characters of the SHA-1 ID and the commit one line
-summary at the end of your commit message. For example: ::
-
-  Fixes: 123456789012 ("The commit that caused the issue")
-
-For further reading, please see
-`'on commit messages' <http://who-t.blogspot.de/2009/12/on-commit-messages.html>`_
-as a general guideline on what commit messages should contain.
-
-------------------------------------------------------------------------------
-Coding Style
-------------------------------------------------------------------------------
-
-Please see the `CODING_STYLE.md
-<https://gitlab.freedesktop.org/libinput/libinput/blob/main/CODING_STYLE.md>`_
-document in the source tree.
-
-------------------------------------------------------------------------------
-Tracking patches and follow-ups
-------------------------------------------------------------------------------
-
-Once submitted to GitLab, your patches will be reviewed by the libinput
-development team on GitLab. Review may be entirely positive and result in your
-code landing instantly, in which case, great! You're done. However, we may ask
-you to make some revisions: fixing some bugs we've noticed, working to a
-slightly different design, or adding documentation and tests.
-
-If you do get asked to revise the patches, please bear in mind the notes above.
-You should use ``git rebase -i`` to make revisions, so that your patches
-follow the clear linear split documented above. Following that split makes
-it easier for reviewers to understand your work, and to verify that the code
-you're submitting is correct.
-
-A common request is to split single large patch into multiple patches. This can
-happen, for example, if when adding a new feature you notice a bug in
-libinput's core which you need to fix to progress. Separating these changes
-into separate commits will allow us to verify and land the bugfix quickly,
-pushing part of your work for the good of everyone, whilst revision and
-discussion continues on the larger feature part. It also allows us to direct
-you towards reviewers who best understand the different areas you are
-working on.
-
-When you have made any requested changes, please rebase the commits, verify
-that they still individually look good, then force-push your new branch to
-GitLab. This will update the merge request and notify everyone subscribed to
-your merge request, so they can review it again.
-
-There are also many GitLab CLI clients, if you prefer to avoid the web
-interface. It may be difficult to follow review comments without using the
-web interface though, so we do recommend using this to go through the review
-process, even if you use other clients to track the list of available
-patches.
-
-------------------------------------------------------------------------------
-Failed pipeline errors
-------------------------------------------------------------------------------
-
-After submitting your merge request to GitLab, you might receive an email
-informing you that your pipeline failed.
-
-Visit your merge request page and check the `pipeline mini graph
-<https://docs.gitlab.com/ee/ci/pipelines/#pipeline-mini-graphs>`_ to know which
-step failed.
-
-Follow the appropriate section to fix the errors.
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Committed gitlab-ci.yml differs from generated gitlab-ci.yml. Please verify
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-When your merge request modifies the CI templates, you might see this error
-mainly due two reasons: the wrong file was modified and/or
-``ci-fairy generate-template`` wasn't run.
-
-``.gitlab-ci.yaml`` is auto generated, changes should be made in:
-
-- ``.gitlab-ci/ci.template``
-
-- ``.gitlab-ci/config.yaml``
-
-Once the changes are ready, run
-`ci-fairy <https://freedesktop.pages.freedesktop.org/ci-templates/ci-fairy.html#templating-gitlab-ci-yml>`_
-to update ``.gitlab-ci.yaml``: ::
-
-  ci-fairy generate-template
-
-Finally, force-push you changes. See :ref:`contributing_submitting_code` for
-more details.
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Build errors
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Usually, checking the CI log is enough to catch this errors. However, your merge
-request is built using different configurations you might have not tested.
-
-In order to fix this kind of problems, you can compile libinput using the same
-flags used by the CI.
-
-For example, if an error is found in the ``build-no-libwacom`` step, open the
-log and search the build options: ::
-
-  [...]

-.. _udev_config:
-
-==============================================================================
-Static device configuration via udev
-==============================================================================
-
-libinput supports some static configuration through udev properties.
-These properties are read when the device is initially added
-to libinput's device list, i.e. before the
-**LIBINPUT_EVENT_DEVICE_ADDED** event is generated.
-
-The following udev properties are supported:
-
-LIBINPUT_CALIBRATION_MATRIX
-    Sets the calibration matrix, see
-    **libinput_device_config_calibration_get_default_matrix()**. If unset,
-    defaults to the identity matrix.
-
-    The udev property is parsed as 6 floating point numbers separated by a
-    single space each (scanf(3) format ``"%f %f %f %f %f %f"``).
-    The 6 values represent the first two rows of the calibration matrix as
-    described in **libinput_device_config_calibration_set_matrix()**.
-
-    Example values are: ::
-
-          ENV{LIBINPUT_CALIBRATION_MATRIX}="1 0 0 0 1 0" # default
-          ENV{LIBINPUT_CALIBRATION_MATRIX}="0 -1 1 1 0 0" # 90 degree clockwise
-          ENV{LIBINPUT_CALIBRATION_MATRIX}="-1 0 1 0 -1 1" # 180 degree clockwise
-          ENV{LIBINPUT_CALIBRATION_MATRIX}="0 1 0 -1 0 1" # 270 degree clockwise
-          ENV{LIBINPUT_CALIBRATION_MATRIX}="-1 0 1 0 1 0" # reflect along y axis
-
-
-LIBINPUT_DEVICE_GROUP
-    A string identifying the **libinput_device_group** for this device. Two
-    devices with the same property value are grouped into the same device group,
-    the value itself is irrelevant otherwise.
-
-LIBINPUT_IGNORE_DEVICE
-    If set to anything other than "0", the device is ignored by libinput.
-    See :ref:`ignoring_devices` for more details.
-
-ID_SEAT
-    Assigns the physical :ref:`seat <seats>` for this device. See
-    **libinput_seat_get_physical_name()**. Defaults to "seat0".
-
-ID_INPUT
-    If this property is set, the device is considered an input device. Any
-    device with this property missing will be ignored, see :ref:`udev_device_type`.
-
-ID_INPUT_KEYBOARD, ID_INPUT_KEY, ID_INPUT_MOUSE, ID_INPUT_TOUCHPAD, ID_INPUT_TOUCHSCREEN, ID_INPUT_TABLET, ID_INPUT_JOYSTICK, ID_INPUT_ACCELEROMETER
-    If any of the above is set, libinput initializes the device as the given
-    type, see :ref:`udev_device_type`. Note that for historical reasons more than
-    one of these may be set at any time, libinput will select only one of these
-    to determine the device type. To ensure libinput selects the correct device
-    type, only set one of them.
-
-WL_SEAT
-    Assigns the logical :ref:`seat <seats>` for this device. See
-    **libinput_seat_get_logical_name()** context. Defaults to "default".
-
-MOUSE_DPI
-    HW resolution and sampling frequency of a relative pointer device.
-    See :ref:`motion_normalization` for details.
-
-MOUSE_WHEEL_CLICK_ANGLE
-    The angle in degrees for each click on a mouse wheel. See
-    **libinput_pointer_get_axis_source()** for details.
-
-
-Below is an example udev rule to assign "seat1" to a device from vendor
-``0x012a`` with the model ID of ``0x034b``. ::
-
-   $ cat /etc/udev/rules.d/99-my-device-is-on-seat1.rules
-     ACTION!="remove", KERNEL=="event[0-9]*", \
-     ENV{ID_VENDOR_ID}=="012a", \

-
-.. _udev_device_type:
-
-------------------------------------------------------------------------------
-Device type assignment via udev
-------------------------------------------------------------------------------
-
-libinput requires the **ID_INPUT** property to be set on a device,
-otherwise the device will be ignored. In addition, one of
-**ID_INPUT_KEYBOARD, ID_INPUT_KEY, ID_INPUT_MOUSE, ID_INPUT_TOUCHPAD,
-ID_INPUT_TOUCHSCREEN, ID_INPUT_TABLET, ID_INPUT_JOYSTICK,
-ID_INPUT_ACCELEROMETER** must be set on the device to determine the
-device type. The usual error handling applies within libinput and a device
-type label does not guarantee that the device is initialized by libinput.
-If a device fails to meet the requirements for a device type (e.g. a keyboard
-labelled as touchpad) the device will not be available through libinput.
-
-Only one device type should be set per device at a type, though libinput can
-handle some combinations for historical reasons.
-
-Below is an example udev rule  to remove an **ID_INPUT_TOUCHPAD** setting
-and change it into an **ID_INPUT_TABLET** setting. This rule would apply
-for a device with the vendor/model ID of ``012a``/``034b``. ::
-
-   $ cat /etc/udev/rules.d/99-my-device-is-a-tablet.rules
-     ACTION!="remove", KERNEL=="event[0-9]*", \

-
-As of libinput 1.12, model-specific configuration is stored in the

-details.
-
-.. _model_specific_configuration_x220fw81:
-
-..............................................................................
-Lenovo x220 with touchpad firmware v8.1
-..............................................................................
-
-The property **LIBINPUT_MODEL_LENOVO_X220_TOUCHPAD_FW81** may be set by a
-user in a local hwdb file. This property designates the touchpad on a Lenovo
-x220 with a touchpad firmware version 8.1. When this firmware version is
-installed, the touchpad is imprecise. The touchpad device does not send
-continuous x/y axis position updates, a behavior also observed on its
-successor model, the Lenovo x230 which has the same firmware version. If the
-above property is set, libinput adjusts its behavior to better suit this
-particular model.
-
-The touchpad firmware version cannot be detected automatically by libinput,
-local configuration is required to set this property. Refer to the libinput
-model quirks hwdb for instructions.
-
-This property must not be used for any other purpose, no specific behavior
-is guaranteed.
-
-
-.. _hwdb:

-
-This section outlines how to query the
-`udev hwdb <https://www.freedesktop.org/software/systemd/man/hwdb.html>`_
-and reload properties so they are available to libinput.
-
-The hwdb contains a set of match rules that assign udev properties that are
-available to libinput when the device is connected and/or libinput is
-initialized. This section only describes the hwdb in relation to libinput,
-it is not a full documentation on how the hwdb works.
-
-libinput's use of the hwdb is limited to properties systemd and custom
-rules files (where available) provide. Hardware-specific quirks as used by
-libinput are in the :ref:`device-quirks` system.
-
-.. _hwdb_querying:
-
-..............................................................................
-Querying the hwdb
-..............................................................................
-
-libinput only uses device nodes in the form of ``/dev/input/eventX`` where X
-is the number of the specific device. Running ``libinput debug-events`` lists
-all devices currently available to libinput and their event node name: ::
-
-    $> sudo libinput debug-events
-    -event2   DEVICE_ADDED     Power Button                      seat0 default group1  cap:k
-    -event5   DEVICE_ADDED     Video Bus                         seat0 default group2  cap:k
-    -event0   DEVICE_ADDED     Lid Switch                        seat0 default group3  cap:S
-
-    ...
-
-Note the event node name for your device and translate it into a syspath in
-the form of ``/sys/class/input/eventX``. This path can be supplied to ``udevadm
-info`` ::
-
-    $> udevadm info
-    P: /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0D:00/input/input0/event0
-    N: input/event0
-    E: DEVNAME=/dev/input/event0

-    E: ID_INPUT=1
-    E: ID_INPUT_SWITCH=1
-    E: MAJOR=13
-    E: MINOR=64
-    E: SUBSYSTEM=input
-    E: TAGS=:power-switch:
-    E: USEC_INITIALIZED=7167898
-
-Lines starting with ``E:`` are udev properties available to libinput. For
-example, the above device's ``ID_INPUT_SWITCH`` property will cause libinput
-to treat this device as switch device.
-
-
-.. _hwdb_reloading:
-
-..............................................................................
-Reloading the hwdb
-..............................................................................
-
-The actual hwdb is stored in binary file on-disk and must be updated
-manually whenever a ``.hwdb`` file changes. This is required both when a user
-manually edits the ``.hwdb`` file but also when the git tree is updated (and
-that update causes a hwdb change).
-
-To update the binary file on-disk, run: ::
-
-    sudo systemd-hwdb update
-
-Then, to trigger a reload of all properties on your device, run: ::
-
-    sudo udevadm trigger /sys/class/input/eventX
-
-Then check with ``udevadm info`` whether the properties were updated, see
-:ref:`hwdb_querying`. If a new property does not appear on the device, use ``udevadm
-test`` to check for error messages by udev and the hwdb (e.g. syntax errors
-in the udev rules files). ::
-
-    sudo udevadm test /sys/class/input/eventX
-
-.. warning::  ``udevadm test`` does not run commands specified in ``RUN``
-	      directives. This affects the udev properties relying on e.g.
-	      the udev keyboard builtin such as the :ref:`touchpad_jitter`
-	      workarounds.
-
-.. _hwdb_modifying:
-
-..............................................................................
-Modifying the hwdb
-..............................................................................
-
-.. warning:: This section has been removed as it no longer applies in libinput 1.12
-             and later. libinput users should not need to modify the hwdb, any
-             device-specific quirks must go in to the :ref:`device-quirks` system.

-Device quirks
-==============================================================================
-
-libinput requires extra information from devices that is not always readily
-available. For example, some touchpads are known to have jumping cursors
-under specific conditions. libinput ships a set of files containing the
-so-called model quirks to provide that information. Model quirks are usually
-installed under ``/usr/share/libinput/<filename>.quirks`` and are standard
-``.ini`` files. A file may contain multiple section headers (``[some
-identifier]``) followed by one or more :ref:`MatchFoo=Bar <device-quirks-matches>`
-directives, followed by at least one of ``ModelFoo=1`` or ``AttrFoo=bar`` directive.
-See the ``quirks/README.md`` file in the libinput source repository for more
-details on their contents.
-
-.. warning:: Model quirks are internal API and may change at any time. No
-             backwards-compatibility is guaranteed.
-
-For example, a quirks file may have this content to label all keyboards on
-the serial bus (PS/2) as internal keyboards: ::
-
-     [Serial Keyboards]
-     MatchUdevType=keyboard
-     MatchBus=serial
-     AttrKeyboardIntegration=internal
-
-
-The model quirks are part of the source distribution and should never be
-modified locally. Updates to libinput may overwrite modifications or even
-stop parsing any property. For temporary local workarounds, see
-:ref:`device-quirks-local`.
-
-Device quirks are parsed on libinput initialization. A parsing error in the
-device quirks disables **all** device quirks and may negatively impact
-device behavior on the host. If the quirks cannot be loaded, an error
-message is posted to the log and users should use the information in
-:ref:`device-quirks-debugging` to verify their quirks files.
-
-.. _device-quirks-local:
-
-------------------------------------------------------------------------------
-Installing temporary local device quirks

-``/etc/libinput/local-overrides.quirks`` file. Users may add sections to
-this file to add a device quirk for a local device but beware that **any
-modification must be upstreamed** or it may cease to work at any time.
-
-.. warning:: Model quirks are internal API and may change at any time. No
-             backwards-compatibility is guaranteed. Local overrides should only
-             be used until the distribution updates the libinput packages.

-             No guarantee is given that any quirk below works on your version of
-             libinput.
-
-In the documentation below, the letters N, M, O, P refer to arbitrary integer
-values.
-
-Quirks starting with **Model*** triggers implementation-defined behaviour
-for this device not needed for any other device. Only the more
-general-purpose **Model*** flags are listed here.
-
-ModelALPSTouchpad, ModelAppleTouchpad, ModelWacomTouchpad, ModelChromebook
-    Reserved for touchpads made by the respective vendors
-ModelTouchpadVisibleMarker
-    Indicates the touchpad has a drawn-on visible marker between the software
-    buttons.
-ModelTabletModeNoSuspend
-    Indicates that the device does not need to be
-    suspended in :ref:`switches_tablet_mode`.
-ModelTabletModeSwitchUnreliable
-    Indicates that this tablet mode switch's state cannot be relied upon.
-ModelTrackball
-    Reserved for trackballs
-ModelBouncingKeys
-    Indicates that the device may send fake bouncing key events and
-    timestamps can not be relied upon.
-ModelSynapticsSerialTouchpad
-    Reserved for touchpads made by Synaptics on the serial bus
-ModelPressurePad
-    .. warning:: This quirk is no longer in use. Use
-                 ``AttrInputProp=+INPUT_PROP_PRESSUREPAD`` instead.
-
-    Unlike in traditional touchpads, whose pressure value equals contact size,
-    on pressure pads pressure is a real physical axis.
-    Indicates that the device is a pressure pad.
-ModelTouchpadPhantomClicks
-    Some laptops are prone to registering touchpad clicks when the case is
-    bent. Indicates that clicks should be ignored if no fingers are on the
-    touchpad.
-ModelScrollOnMiddleClick
-    Some mice can generate unwanted high-resolution scroll events when the wheel
-    is pressed. Increases the scroll threshold required to start scrolling to
-    avoid accidentally scrolling when middle clicking.
-AttrSizeHint=NxM, AttrResolutionHint=N
-    Hints at the width x height of the device in mm, or the resolution
-    of the x/y axis in units/mm. These may only be used where they apply to
-    a large proportion of matching devices. They should not be used for any
-    specific device, override ``EVDEV_ABS_*`` instead, see
-    :ref:`absolute_coordinate_ranges_fix`.
-AttrTouchSizeRange=N:M, AttrPalmSizeThreshold=O
-    Specifies the touch size required to trigger a press (N) and to trigger
-    a release (M). O > N > M. See :ref:`touchpad_touch_size_hwdb` for more
-    details.
-    An AttrPalmSizeThreshold of zero unsets any threshold that has been
-    inherited from another quirk.
-AttrPressureRange=N:M, AttrPalmPressureThreshold=O, AttrThumbPressureThreshold=P
-    Specifies the touch pressure required to trigger a press (N) and to
-    trigger a release (M), when a palm touch is triggered (O) and when a
-    thumb touch is triggered (P). O > P > N > M. See
-    :ref:`touchpad_pressure_hwdb` for more details.
-    An AttrPalmPressureThreshold of zero unsets any threshold that has been
-    inherited from another quirk.
-AttrLidSwitchReliability=reliable|unreliable|write_open
-    Indicates the reliability of the lid switch. This is a string enum.
-    Very few devices need this, if in doubt do not set. See :ref:`switches_lid`
-    for details. libinput 1.21.0 changed the default from unreliable to
-    reliable, which may be removed from local overrides.
-AttrKeyboardIntegration=internal|external
-    Indicates the integration of the keyboard. This is a string enum.
-    Generally only needed for USB keyboards.
-AttrTPKComboLayout=below
-    Indicates the position of the touchpad on an external touchpad+keyboard
-    combination device. This is a string enum. Don't specify it unless the
-    touchpad is below.
-AttrEventCode=+EV_ABS;-BTN_STYLUS;+EV_KEY:0x123;
-    Enables or disables the evdev event type/code tuples on the device. The prefix
-    for each entry is either '+' (enable) or '-' (disable). Entries may be
-    a named event type, or a named event code, or a named event type with a
-    hexadecimal event code, separated by a single colon.
-AttrInputProp=+INPUT_PROP_BUTTONPAD;-INPUT_PROP_POINTER;
-    Enables or disables the evdev input property on the device. The prefix
-    for each entry is either '+' (enable) or '-' (disable). Entries may be
-    a named input property or the hexadecimal value of that property.
-
-    The most common use of this is ``AttrInputProp=+INPUT_PROP_PRESSUREPAD``
-    which marks a touchpad as a :ref:`forcepad or pressurepad <touchpads_buttons_forcepads>`.
-AttrPointingStickIntegration=internal|external
-    Indicates the integration of the pointing stick. This is a string enum.
-    Only needed for external pointing sticks. These are rare.
-AttrTabletSmoothing=1|0
-    Enables (1) or disables (0) input smoothing for tablet devices. Smoothing is enabled
-    by default, except on AES devices.

-    by a udev rule. These matches use ``fnmatch()`` globs.
-MatchBus
-    A lower-case bus name. Currently supported are ``usb``, ``bluetooth``, ``ps2``,
-    ``rmi``, ``i2c``, and ``spi``.
-MatchVendor, MatchProduct, MatchVersion
-    The hexadecimal 4-digit vendor ID, product ID or driver version as
-    exported, uppercase with a ``0x`` prefix, e.g. ``0x12AB```.
-MatchDMIModalias, MatchDeviceTree
-    An ``fnmatch()`` glob for the DMI modalias or the DeviceTree ``compatible`` string.
-    See ``/sys/class/dmi/id/modalias`` and ``/sys/firmware/devicetree/base/compatible``.
-MatchUdevType
-    One of ``touchpad``, ``mouse``, ``pointingstick``, ``keyboard``, ``joystick``,
-    ``tablet``, ``tablet-pad``. Matches the corresponding ``ID_INPUT_*`` udev
-    property.

-==============================================================================
-Three-finger drag
-==============================================================================
-
-Three-finger drag is a feature available on touchpads that emulates logical
-button presses if three fingers are moving on the touchpad.
-
-Three-finger drag is independent from :ref:`tapping` though some specific
-behaviors may change when both features are enabled. For example, with
-tapping *disabled* a three-finger gesture will virtually always be a three-finger
-drag. With tapping *enabled* a three finger gesture may be a three finger drag
-and a short delay is required to disambiguate between the two.
-
-
-The exact behavior of three-finger drag is implementation defined and may
-subtly change. As a general rule, the following constraints can be expected:
-
-- three fingers down and movement trigger a button down and subsequent motion
-  events (i.e. a drag)
-- releasing one finger while keeping two fingers down will keep the drag
-  and *not* switch to :ref:`twofinger_scrolling`.
-- releasing two fingers while keeping one finger down will end the drag
-  (and thus release the button) and switch to normal pointer motion
-- releasing all three fingers and putting three fingers back on the touchpad
-  immediately will keep the drag (i.e. behave as if the fingers were
-  never lifted)
-
-  - if tapping is enabled: a three finger tap immediately after a three-finger
-    drag will *not* tap, the user needs to wait past the timeout to
-    three-finger tap
-
-- releasing all three fingers and putting one or two fingers back on
-  the touchpad will end the drag (and thus release the button)
-  and proceed with pointer motion or two-finger scrolling, if applicable
-
-  - if tapping is enabled: a one or two finger tap immediately after a
-    three-finger drag will trigger a one or two finger tap. The user does
-    not have to wait past the drag release timeout

-==============================================================================
-
-Frequently asked questions about libinput.
-
-
-.. contents::
-    :local:
-    :backlinks: entry
-
-.. _faq_feature:
-
-------------------------------------------------------------------------------
-Why doesn't libinput support ...?
-------------------------------------------------------------------------------
-
-First, read :ref:`what_is_libinput` If you have a feature that you think
-libinput needs to support, please file a bug report. See :ref:`reporting_bugs`
-for more details.
-
-.. _faq_fast_mouse:
-
-------------------------------------------------------------------------------
-My mouse moves too fast, even at the slowest setting
-------------------------------------------------------------------------------
-
-This is a symptom of high-dpi mice (greater than 1000dpi). These devices
-need a udev hwdb entry to normalize their motion. See
-:ref:`motion_normalization` for a detailed explanation.
-
-.. _faq_fast_trackpoint:
-
-------------------------------------------------------------------------------
-My trackpoint moves too slow or too fast
-------------------------------------------------------------------------------
-
-This is a symptom of an invalid trackpoint multiplier. These devices need
-:ref:`device-quirks` to specify the range available so libinput can adjust the
-pointer acceleration accordingly. See :ref:`trackpoint_range` for a detailed
-explanation.
-
-.. _faq_pointer_acceleration:
-
-------------------------------------------------------------------------------
-Why is libinput's pointer acceleration worse than synaptics/evdev
-------------------------------------------------------------------------------
-
-This is a known problem affecting some devices and/or use-case but the exact
-cause is still unknown. It may be a device-specific issue, it may be a bug
-in libinput's acceleration code, it may be a disagreement about how pointer
-acceleration should feel. Unfortunately this is something that affected
-users need to investigate and analyze.
-
-.. _faq_enable_tapping:
-
-------------------------------------------------------------------------------
-Why isn't touchpad tap-to-click enabled by default
-------------------------------------------------------------------------------
-
-See :ref:`tapping_default`
-
-.. _faq_touchpad_pressure:
-
-------------------------------------------------------------------------------
-Why does my touchpad lose track of touches
-------------------------------------------------------------------------------
-
-The most common cause for this is an incorrect pressure threshold range.
-See :ref:`touchpad_pressure` for more info.
-
-.. _faq_kinetic_scrolling:
-
-------------------------------------------------------------------------------
-Kinetic scrolling does not work
-------------------------------------------------------------------------------
-
-The X.Org synaptics driver implemented kinetic scrolling in the driver. It
-measures the scroll speed and once the finger leaves the touchpad the driver
-keeps sending scroll events for a predetermined time. This effectively
-provides for kinetic scrolling without client support but triggers an
-unfixable `bug <https://bugs.freedesktop.org/show_bug.cgi?id=38909>`_: the
-client cannot know that the events are from a kinetic scroll source. Scroll
-events in X are always sent to the current cursor position, a movement of the
-cursor after lifting the finger will send the kinetic scroll events to the
-new client, something the user does not usually expect. A key event during
-the kinetic scroll procedure causes side-effects such as triggering zoom.
-
-libinput does not implement kinetic scrolling for touchpads. Instead it
-provides the **libinput_event_pointer_get_axis_source()** function that enables
-callers to implement kinetic scrolling on a per-widget basis, see
-:ref:`scroll_sources`.
-
-.. _faq_gpl:
-
-------------------------------------------------------------------------------
-Is libinput GPL-licensed?
-------------------------------------------------------------------------------
-
-No, libinput is MIT licensed. The Linux kernel header file linux/input.h in
-libinput's tree is provided to ensure the same behavior regardless of which
-kernel version libinput is built on. It does not make libinput GPL-licensed.
-
-.. _faq_config_options:
-
-------------------------------------------------------------------------------
-Where is the configuration stored?
-------------------------------------------------------------------------------
-
-libinput does not store configuration options, it is up to the caller to
-manage these and decide which configuration option to apply to each device.
-This must be done at startup, after a resume and whenever a new device is
-detected.
-
-One commonly used way to configure libinput is to have the Wayland
-compositor expose a compositor-specific configuration option. For example,
-in a GNOME stack, the gnome-control-center modifies dconf entries. These
-changes are read by mutter and applied to libinput. Changing these entries
-via the gsettings commandline tool has the same effect.
-
-Another commonly used way to configure libinput is to have xorg.conf.d
-snippets. When libinput is used with the xf86-input-libinput driver in an
-X.Org stack, these options are read on startup and apply to each device.
-Changing properties at runtime with the xinput commandline tool has the same
-effect.
-
-In both cases, the selection of available options and how they are exposed
-depends on the libinput caller (e.g. mutter or xf86-input-libinput).
-
-.. graphviz:: libinput-stack-gnome.gv
-
-This has an effect on the availability of configuration options: if an
-option is not exposed by the intermediary, it cannot be configured by the
-client. Also some configuration options that are provided by the
-intermediary may not be libinput-specific configuration options.
-
-.. _faq_configure_wayland:
-
-------------------------------------------------------------------------------
-How do I configure my device on Wayland?
-------------------------------------------------------------------------------
-
-See :ref:`faq_config_options` Use the configuration tool provided by your
-desktop environment (e.g. gnome-control-center) or direct access to your
-desktop environment's configuration storage (e.g. gsettings).
-
-.. _faq_configure_xorg:
-
-------------------------------------------------------------------------------
-How do I configure my device on X?
-------------------------------------------------------------------------------
-
-See :ref:`faq_config_options`  If your desktop environment does not provide a
-graphical configuration tool you can use an
-`xorg.conf.d snippet <https://www.x.org/archive/current/doc/man/man5/xorg.conf.5.xhtml>`_.
-Usually, such a snippet looks like this:
-
-::
-
-     $> cat /etc/X11/xorg.conf.d/99-libinput-custom-config.conf
-     Section "InputClass"
-       Identifier "something to identify this snippet"
-       MatchDriver "libinput"
-       MatchProduct "substring of the device name"
-       Option "some option name" "the option value"
-     EndSection
-
-
-The identifier is merely a human-readable string that shows up in the log
-file. The MatchProduct line should contain the device name or a substring of
-the device name that the snippet should apply to. For a full list of option
-names and permitted values, see the
-`libinput man page <https://www.mankier.com/4/libinput>`_.
-xorg.conf.d snippets like the above apply to hotplugged devices but can be
-overwritten at runtime by desktop tools. Multiple snippets may be placed
-into the same file.
-
-For run-time configuration and testing, the
-`xinput <https://www.x.org/archive/X11R7.5/doc/man/man1/xinput.1.html>`_
-debugging tool can modify a devices' properties. See the
-`libinput man page <https://www.mankier.com/4/libinput>`_
-for supported property names and values. Usually, an invocation looks like
-this:
-
-::
-
-     $> xinput set-prop "the device name" "the property name" value [value2] [value3]
-
-
-.. note:: Changes performed by xinput do not persist across device hotplugs. xinput
-	is considered a debugging and testing tool only and should not be used
-	for permanent configurations.
-
-.. _faq_configuration:
-
-------------------------------------------------------------------------------
-Can you add a configuration option for $FEATURE?
-------------------------------------------------------------------------------
-
-No. At least that's going to be the initial answer. Read
-`Why libinput doesn't have a lot of configuration options <http://who-t.blogspot.com/2016/04/why-libinput-doesnt-have-lot-of-config.html>`_
-first. Configuration options for most features are a signal that we are incapable
-of handling it correctly. To get to that point, we want to be sure we're
-truly incapable of doing so. libinput has several features that
-are handled automatically (and correctly) that users wanted to have
-configuration options for initially.
-
-So the answer to this question will almost always be 'no'. A configuration
-option is, in most cases, a cop-out.
-
-.. _faq_synclient:
-
-------------------------------------------------------------------------------
-Why don't synclient and syndaemon work with libinput?
-------------------------------------------------------------------------------
-
-Synclient and syndaemon rely on X input device properties that are specific
-to the xf86-input-synaptics X.Org input driver. Both were written when the
-synaptics driver was the only common touchpad driver in existence. They
-assume that if the properties aren't available, no touchpad is available
-either. The xf86-input-libinput X.Org input driver does not export these
-driver-specific properties, synclient/syndaemon will thus not detect the
-touchpad and refuse to work. Other tools that rely on synclient/syndaemon or
-those same properties also do not work with xf86-input-libinput.
-
-Most of syndaemon's functionality is built into libinput, see
-:ref:`disable-while-typing`. synclient is merely a configuration tool, see
-:ref:`faq_configure_xorg` for similar functionality.
-
-See also the blog posts
-`The definitive guide to synclient <http://who-t.blogspot.com.au/2017/01/the-definitive-guide-to-synclient.html>`_ and
-`The future of xinput, xmodmap, setxkbmap, xsetwacom and other tools under Wayland <http://who-t.blogspot.com.au/2016/12/the-future-of-xinput-xmodmap-setxkbmap.html>`_
-
-.. _faq_tablets:
-
-------------------------------------------------------------------------------
-Does libinput support non-Wacom tablets?
-------------------------------------------------------------------------------
-
-Yes, though unfortunately many non-Wacom tablets suffer from bad firmware
-and don't send the required events. But they should all work nonetheless. If
-you have a tablet that does not work with libinput, please
-:ref:`file a bug <reporting_bugs>`.
-
-.. _faq_tablet_capabilities:
-
-------------------------------------------------------------------------------
-My tablet doesn't work
-------------------------------------------------------------------------------
-
-If you see the message
-
-::
-
-     libinput bug: device does not meet tablet criteria. Ignoring this device.
-
-
-or the message
-
-::
-
-     missing tablet capabilities [...] Ignoring this device.
-
-
-your tablet device does not have the required capabilities to be treated as
-a tablet. This is usually a problem with the device and the kernel driver.
-See :ref:`tablet-capabilities` for more details.
-
-.. _faq_hwdb_changes:
-
-------------------------------------------------------------------------------
-How to apply hwdb changes
-------------------------------------------------------------------------------
-
-Sometimes users are asked to test updates to the
-`udev hwdb <https://www.freedesktop.org/software/systemd/man/hwdb.html>`_
-or patches that include a change to the hwdb. See :ref:`hwdb` for
-details on the hwdb and how to modify it locally.
-
-.. note:: As of libinput 1.12, libinput-specific properties are now stored in
-	the :ref:`device-quirks` system. There are no libinput-specific hwdb
-	entries anymore and any changes to the hwdb must be merged into the
-	systemd repository.
-
-.. _faq_timer_offset:
-
-------------------------------------------------------------------------------
-What causes the "your system is too slow" warning?
-------------------------------------------------------------------------------
-
-libinput relies on the caller to call **libinput_dispatch()** whenever data is
-available. **libinput_dispatch()** will process the state of all devices,
-including some time-sensitive features (e.g. palm detection, tap-to-click,
-disable-while-typing, etc.).
-
-If the time between the event and the call to **libinput_dispatch()**
-is excessive, those features may not work correctly. For example, a delay in
-touch event processing may cause wrong or missing tap-to-click events or
-a palm may not be detected correctly.
-
-When this warning appears, it simply means that too much time has passed
-between the event occurring and the current time. In almost all cases this
-is an indication of the caller being overloaded and not handling events as
-speedily as required.
-
-The warning has no immediate effect on libinput's behavior but some of the
-functionality that relies on the timer may be impeded. This is not a bug in
-libinput. libinput does not control how quickly **libinput_dispatch()** is
-called.
-
-.. _faq_wayland:
-
-------------------------------------------------------------------------------
-Is libinput required for Wayland?
-------------------------------------------------------------------------------
-
-Technically - no. But for your use-case - probably.
-
-Wayland is a display server communication protocol. libinput is a low-level
-library to simplify handling input devices and their events. They have no
-direct connection. As a technical analogy, the question is similar to "is
-glibc required for HTTP", or (stretching the analogy a bit further) "Is a
-pen required to write English". No, it isn't.
-
-You can use libinput without a Wayland compositor, you can write a Wayland
-compositor without libinput. On most major distributions, libinput is the
-standard input stack used with the X.Org X server through the
-xf86-input-libinput driver.
-
-So why "for your use-case - probably"?  All general-purpose Wayland
-compositors use libinput for their input stack. Wayland compositors that
-are more specialized (e.g. in-vehicle infotainment or IVI) can handle input
-devices directly but the compositor you want to use
-on your desktop needs an input stack that is more complex. And right now,
-libinput is the only input stack that exists for this use-case.
-
-.. _faq_separate_contexts:
-
-------------------------------------------------------------------------------
-Can I write a program to make libinput do $FOO
-------------------------------------------------------------------------------
-
-A common question is whether it's possible to write a program that can change
-libinput's behavior - specifically the libinput that is used inside the
-compositor. This indicates a misunderstanding of how libinput works:
-libinput is a library that converts kernel events into libinput events, much
-like ``sed`` reads data in, modifies it, and provides it to stdout.
-
-.. graphviz:: libinput-contexts.gv
-
-A libinput context is private to the process and cannot be modified from the
-outside. To use the ``sed`` analogy again: if ``sed`` is used by a
-shell-script, that script has full control over how ``sed`` processes data. In
-this analogy, ``sed`` is libinput and the shell script is the compositor. It is
-not possible to write a program to modify the behavior of the ``sed`` instance
-used inside that shell script.
-
-Writing a program that uses libinput is akin to writing a new script that
-invoke ``sed``. It will not have any effect on the original ``sed`` instance.
-
-The only way to modify libinput's behavior is to use the configuration options
-exposed by the respective compositor. Those affect the libinput context inside
-the compositor and thus have an effect on the input device behavior.
-
-.. _faq_debug_events_not_showing_configuration:
-
-------------------------------------------------------------------------------
-Why doesn't libinput debug-events show my configuration
-------------------------------------------------------------------------------
-
-See :ref:`faq_separate_contexts`.
-
-------------------------------------------------------------------------------
-Can I configure scroll speed?
-------------------------------------------------------------------------------
-
-No, or at least, not as a libinput option.
-
-When using a mouse, libinput notifies callers about physical scroll wheel
-movement. When using another device, libinput notifies scroll in scroll units.
-
-It is up to the caller to transform those events into a number of pixels to
-scroll and, if desired, provide a way to adjust scroll speed.
-
-This transformation cannot be done in libinput because it may depend on context
-only known by the caller. For example, a caller may want to scroll faster
-depending on how many pages a document has or depending on the widget that
-receives the scroll events.

-Gestures
-==============================================================================
-
-libinput supports :ref:`gestures_pinch` and :ref:`gestures_swipe` on most
-modern touchpads and other indirect touch devices. Note that libinput **does
-not** support gestures on touchscreens, see :ref:`gestures_touchscreens`.
-
-.. _gestures_lifetime:
-
------------------------------------------------------------------------------
-Lifetime of a gesture
------------------------------------------------------------------------------
-
-A gesture starts when the finger position and/or finger motion is
-unambiguous as to what gesture to trigger and continues until the first
-finger belonging to this gesture is lifted.
-
-A single gesture cannot change the finger count. For example, if a user
-puts down a fourth finger during a three-finger swipe gesture, libinput will
-end (cancel) the three-finger gesture and, if applicable, start a
-four-finger swipe gesture. A caller may however decide that those gestures
-are semantically identical and continue the two gestures as one single
-gesture.
-
-.. _gestures_pinch:
-
-------------------------------------------------------------------------------
-Pinch gestures
-------------------------------------------------------------------------------
-
-Pinch gestures are executed when two or more fingers are located on the
-touchpad and are either changing the relative distance to each other
-(pinching) or are changing the relative angle (rotate). Pinch gestures may
-change both rotation and distance at the same time. For such gestures,
-libinput calculates a logical center for the gestures and provides the
-caller with the delta x/y coordinates of that center, the relative angle of
-the fingers compared to the previous event, and the absolute scale compared
-to the initial finger position.
-
-.. figure:: pinch-gestures.svg
-    :align: center
-
-    The pinch and rotate gestures
-
-The illustration above shows a basic pinch in the left image and a rotate in
-the right angle. Not shown is a movement of the logical center if the
-fingers move unevenly. Such a movement is supported by libinput, it is
-merely left out of the illustration.
-
-Note that while position and angle is relative to the previous event, the
-scale is always absolute and a multiplier of the initial finger position's
-scale.
-
-.. _gestures_swipe:
-
-------------------------------------------------------------------------------
-Swipe gestures
-------------------------------------------------------------------------------
-
-Swipe gestures are executed when three or more fingers are moved
-synchronously in the same direction. libinput provides x and y coordinates
-in the gesture and thus allows swipe gestures in any direction, including
-the tracing of complex paths. It is up to the caller to interpret the
-gesture into an action or limit a gesture to specific directions only.
-
-.. figure:: swipe-gestures.svg
-    :align: center
-
-    The swipe gestures
-
-The illustration above shows a vertical three-finger swipe. The coordinates
-provided during the gesture are the movements of the logical center.
-
-.. _gestures_hold:
-
-------------------------------------------------------------------------------
-Hold gestures
-------------------------------------------------------------------------------
-
-A hold gesture is one where the user places one or more fingers on the
-device without significant movement. The exact conditions when a hold gesture
-transitions to pointer motion, scrolling or other gestures
-are implementation-defined.
-
-The hold gesture is intended to allow for the implementation of two specific
-features:
-
-- where a two-finger scrolling starts kinetic scrolling in the caller, a
-  subsequent hold gesture can be used to stop that kinetic scroll motion,
-  and
-- hold-to-trigger interactions where the interaction could be a click, a
-  context menu, or some other context-specific interaction.
-
-Hold gestures have three potential logical states:
-
-- **begin**: one or more fingers are placed on the device at the same time
-- **end**: all fingers are removed and the device enters a neutral logical state
-- **end(cancelled)**: all fingers are part of a known interaction and the
-  current hold gesture is no longer active. This may also occur when
-  switching between hold gestures with different finger counts.
-
-.. note:: By definition, a hold gesture does not move and thus no coordinate
-          updates are available.
-
-For example, a user that puts one finger, then a second finger down and
-releases them later may trigger the following event sequence:
-
-=============  ============  ============
-Action         Event         Finger count
-=============  ============  ============
-Finger 1 down  <no event>
-Finger 2 down  **begin**     2
-Finger 2 up    **end**       2
-Finger 1 up    <no event>
-=============  ============  ============
-
-A hold gesture may by be **cancelled**. This occurs
-when the hold gesture changes into some other interaction and should no
-longer be considered the current hold gesture. A **end(cancelled)** event
-applies to the whole gesture (all fingers). For example, a pointer motion on
-a touchpad may trigger this sequence:
-
-+-------------------+-----------------------+
-| Action            |  Event                |
-+===================+=======================+
-| | Finger 1 down   | | **hold begin**      |
-+-------------------+-----------------------+
-| | Finger 1 motion | | **hold cancel**     |
-| |                 | | **pointer motion**  |
-+-------------------+-----------------------+
-| | Finger 1 motion | | **pointer motion**  |
-+-------------------+-----------------------+
-| | Finger 1 up     | | *no event*          |
-+-------------------+-----------------------+
-
-.. note:: Many interactions with a touchpad will start with a hold
-          gesture that is then cancelled as that gesture turns into e.g.
-          pointer motion. A caller **must** handle hold gesture
-          cancellations correctly.
-
-A two-finger scroll motion on a touchpad may trigger this sequence:
-
-+------------------------+---------------------+--------------+
-| Action                 |  Event              | Finger count |
-+========================+=====================+==============+
-| | Finger 1 down        | | **hold begin**    | | 1          |
-+------------------------+---------------------+--------------+
-| | Finger 2 down        | | **hold cancel**   | | 1          |
-| |                      | | **hold begin**    | | 2          |
-+------------------------+---------------------+--------------+
-| | Finger 1+2 motion    | | **hold cancel**   | | 2          |
-| |                      | | **pointer axis**  | |            |
-+------------------------+---------------------+--------------+
-| | Finger 1+2 motion    | | **pointer axis**  |              |
-+------------------------+---------------------+--------------+
-| | Finger 1 up          | | **pointer axis**  |              |
-| | Finger 2 up          | | (scroll stop)     |              |
-+------------------------+---------------------+--------------+
-
-A three-finger-swipe on a touchpad may trigger this sequence:
-
-+---------------------+---------------------+--------------+
-| Action              |  Event              | Finger count |
-+=====================+=====================+==============+
-| | Finger 1 down     |  | **hold begin**   | | 1          |
-+---------------------+---------------------+--------------+
-| | Finger 2 down     | | **hold cancel**   | | 1          |
-| |                   | | **hold begin**    | | 2          |
-+---------------------+---------------------+--------------+
-| | Finger 3 down     | | **hold cancel**   | | 2          |
-| |                   | | **hold begin**    | | 3          |
-+---------------------+---------------------+--------------+
-| | Finger motion     | | **hold cancel**   | | 3          |
-| |                   | | **swipe begin**   | | 3          |
-+---------------------+---------------------+--------------+
-| | Finger motion     | | **swipe update**  | | 3          |
-+---------------------+---------------------+--------------+
-| | Finger 1 up       | | **swipe end**     | | 3          |
-| | Finger 2 up       | |                   | |            |
-| | Finger 3 up       | |                   | |            |
-+---------------------+---------------------+--------------+
-
-Single-finger hold gestures
-...........................
-
-libinput uses implementation-defined timeouts based on other interactions
-to determine whether a single-finger hold gestures should start. In other
-words, a caller **must not** rely on a hold gesture always being triggered
-as soon as a single finger is placed on the touchpad. This is true for any
-hold gesture but especially so for single-finger hold gestures.
-
-Hold gestures with a single finger are prone to being extremely short-lived.
-On many devices it is impossible to hold a finger still enough for there to
-be no pointer motion events, even if those deltas are miniscule. Changing
-movement thresholds to rely on hold gestures would reduce device
-responsiveness.
-
-It is thus the responsibility of the caller to determine where hold gestures
-transition in and out of other interactions. For example, a two-finger hold
-may produce a cancelled single-finger hold gesture first:
-
-+--------------------+----------------------+--------------+--------------+
-| Action             |  Event               | Finger count | Notes        |
-+====================+======================+==============+==============+
-| | Finger 1 down    | | **hold begin**     | | 1          |              |
-+--------------------+----------------------+--------------+--------------+
-| | Finger 1 motion  | | **hold cancel**    | | 1          | | tiny deltas|
-| |                  | | **pointer motion** | |            | |            |
-+--------------------+----------------------+--------------+--------------+
-| | Finger 2 down    | | **hold begin**     | | 2          |              |
-+--------------------+----------------------+--------------+--------------+
-| | Finger 1 up      | | **hold end**       | |            |              |
-| | Finger 2 up      | |                    | |            |              |
-+--------------------+----------------------+--------------+--------------+
-
-Note how the second hold gesture started with a finger count of 2 - without
-the user ever lifting the first finger. Cancellation of hold gesture does
-not imply the user has lifted a finger.
-
-A hold gesture may start after a previous gesture completed. For example, a
-single finger move-and-hold may trigger different sequences for the same
-user interaction:
-
-+--------------------+---------------------+-------------------+--------------+
-| Action             |  Device 1           | Device 2          | Notes        |
-+====================+=====================+===================+==============+
-| | Finger 1 down    | | **hold begin**    |  | **hold begin** |              |
-+--------------------+---------------------+-------------------+--------------+
-| | Finger 1 motion  | | **hold cancel**   |                   | | tiny deltas|
-|                    | | **pointer motion**|                   | |            |
-+--------------------+---------------------+-------------------+--------------+
-|                    | |  **hold begin**   |                   |              |
-+--------------------+---------------------+-------------------+--------------+
-| |  Finger 1 up     | |  **hold end**     | |  **hold end**   |              |
-+--------------------+---------------------+-------------------+--------------+
-
-A caller that wants to use hold gestures must thus be able to infer the same
-interaction based on a stream of pointer motion events with small deltas.
-
-libinput may start a new hold begin gesture once the pointer stops moving.
-The time between the last pointer motion event and the hold begin event is
-implementation-defined.
-
-
-Hold gestures and thumb/palm detection
-......................................
-
-Thumb and palm detection effectively remove touches from being counted
-towards an interaction, see :ref:`thumb_detection` and
-:ref:`palm_detection` for details.
-
-In the context of hold gestures, thumbs and palms are treated by libinput as
-if the finger was removed from the device. Where other non-thumb/non-palm
-fingers remain on the device, an **hold update** event is sent. Otherwise,
-the hold gesture terminates with a **hold cancel** event.
-
-Notably, libinput's thumb and palm detection is not a simple boolean per
-touch but specific to the state of that touch in the overall context. For
-example, a touch may be a thumb for tapping but not for clickfinger
-interactions. A caller must not infer the number of physical fingers from
-the hold gesture.
-
-Likewise, libinput may classify a finger as thumb in the same hardware event
-as a new finger is placed on the touchpad. In that case, the hold gesture
-**may** continue as one-finger gesture despite there being two physical
-touch points.
-
-Information to determine whether a touch is a thumb or a palm may not be
-available until some time into an interaction. Thus very short brushes
-of the touchpad by a palm may trigger a **hold begin** followed by an
-immediate **hold end** as libinput lacks sufficient information to identify
-the touch as thumb/palm and send the corresponding **hold cancel**
-event. A caller must not assume that a hold gesture always represents a
-valid finger down.
-
-Hold gestures and tap-to-click
-..............................
-
-:ref:`tapping` is the feature that enables short-lived touches to trigger
-button presses.
-
-.. warning:: Summary: do not use hold gestures to do your own tap-to-click
-             implementation
-
-In the context of hold gestures, tap-to-click cancels current hold gestures
-and a finger dragging (see :ref:`tapndrag`) does not begin a hold
-gesture. Where tap-to-click is disabled a tap-like gesture may create
-**hold begin** followed by a **hold end** event. Callers **must not** use
-hold gestures for their own tap-to-click implementation as the data is not
-reliable enough. libinput may change internal timeouts and thresholds
-depending on whether tap-to-click is enabled and the hold gesture event may
-not match touch sequences that a user would expect to be a tap-to-click
-interaction.
-
-.. _gestures_touchscreens:
-
-------------------------------------------------------------------------------
-Touchscreen gestures
-------------------------------------------------------------------------------
-
-Touchscreen gestures are **not** interpreted by libinput. Rather, any touch
-point is passed to the caller and any interpretation of gestures is up to
-the caller or, eventually, the X or Wayland client.
-
-Interpreting gestures on a touchscreen requires context that libinput does
-not have, such as the location of windows and other virtual objects on the
-screen as well as the context of those virtual objects:
-
-.. figure:: touchscreen-gestures.svg
-    :align: center
-
-    Context-sensitivity of touchscreen gestures
-
-In the above example, the finger movements are identical but in the left
-case both fingers are located within the same window, thus suggesting an
-attempt to zoom. In the right case  both fingers are located on a window
-border, thus suggesting a window movement. libinput has no knowledge of the
-window coordinates and thus cannot differentiate the two.
-
-.. _gestures_softbuttons:
-
-------------------------------------------------------------------------------
-Gestures with enabled software buttons
-------------------------------------------------------------------------------
-
-If the touchpad device is a :ref:`Clickpad <touchpads_buttons_clickpads>`, it
-is recommended that a caller switches to :ref:`clickfinger`.
-Usually fingers placed in a :ref:`software button area <software_buttons>`
-are not considered for gestures, resulting in some gestures to be
-interpreted as pointer motion or two-finger scroll events.
-
-.. figure:: pinch-gestures-softbuttons.svg
-    :align: center
-
-    Interference of software buttons and pinch gestures
-
-In the example above, the software button area is highlighted in red. The
-user executes a three-finger pinch gesture, with the thumb remaining in the
-software button area. libinput ignores fingers within the software button
-areas, the movement of the remaining fingers is thus interpreted as a
-two-finger scroll motion.
-
-.. _gestures_twofinger_touchpads:
-
-------------------------------------------------------------------------------
-Gestures on two-finger touchpads
-------------------------------------------------------------------------------
-
-As of kernel 4.2, many :ref:`touchpads_touch_partial_mt` provide only two
-slots. This affects how gestures can be interpreted. Touchpads with only two
-slots can identify two touches by position but can usually tell that there
-is a third (or fourth) finger down on the touchpad - without providing
-positional information for that finger.
-
-Touchpoints are assigned in sequential order and only the first two touch
-points are trackable. For libinput this produces an ambiguity where it is
-impossible to detect whether a gesture is a pinch gesture or a swipe gesture
-whenever a user puts the index and middle finger down first. Since the third
-finger does not have positional information, its location cannot be
-determined.
-
-.. figure:: gesture-2fg-ambiguity.svg
-    :align: center
-
-    Ambiguity of three-finger gestures on two-finger touchpads
-
-The image above illustrates this ambiguity. The index and middle finger are
-set down first, the data stream from both finger positions looks identical.
-In this case, libinput assumes the fingers are in a horizontal arrangement
-(the right image above) and use a swipe gesture.

-Ignoring specific devices
-==============================================================================
-
-If a device has the **LIBINPUT_IGNORE_DEVICE** udev property set to any
-value but "0", that device is not initialized by libinput.
-For a context created with **libinput_udev_create_context()**, the device is
-silently ignored and never shows up. If the device is added with
-**libinput_path_add_device()** to a context created with

-libinput is a library that provides a full input stack for display servers
-and other applications that need to handle input devices provided by the
-kernel.
-
-libinput provides device detection, event handling and abstraction to
-minimize the amount of custom input code the user of libinput need to
-provide the common set of functionality that users expect. Input event
-processing includes scaling touch coordinates, generating
-relative pointer events from touchpads, pointer acceleration, etc.
-
-libinput is not used directly by applications. Think of it more as a device
-driver than an application library. See :ref:`what_is_libinput` for more details.

-Lua Plugins
-==============================================================================
-
-libinput provides a plugin system that allows users to modify the behavior
-of devices. For example, a plugin may add or remove axes and/or buttons on a
-device and/or modify the event stream seen by this device before it is passed
-to libinput.
-
-Plugins are implemented in `Lua <https://www.lua.org/>`_ (version 5.4)
-and are typically loaded from the following paths:
-
-- ``/etc/libinput/plugins/*.lua``, and
-- ``/usr/lib{64}/libinput/plugins/*.lua``
-
-Plugins are loaded in alphabetical order and where
-multiple plugins share the same file name, the one in the highest precedence
-directory is used. Plugins in ``/etc`` take precedence over
-plugins in ``/usr``.
-
-.. note:: Plugins lookup paths and their order are decided by the compositor.
-          Some compositors may support more/fewer/other lookup paths than the
-          above defaults.
-
-Plugins are run sequentially in ascending sort-order (i.e. ``00-foo.lua`` runs
-before ``10-bar.lua``) and each plugin sees the state left by any previous
-plugins. For example if ``00-foo.lua`` changes all left button events to right
-button events, ``10-bar.lua`` only ever sees right button events.
-
-See the `Lua Reference manual <https://www.lua.org/manual/5.4/manual.html>`_ for
-details on the Lua language.
-
-.. note:: Plugins are **not** loaded by default, it is up to the compositor
-          whether to allow plugins. An explicit call to
-          ``libinput_plugin_system_load_plugins()`` is required.
-
-------------------------------------------------------------------------------
-Limitations
-------------------------------------------------------------------------------
-
-Each script runs in its own sandbox and cannot communicate or share state with
-other scripts.
-
-Tables that hold API methods are not writable, i.e. it is not possible
-to overwrite the default functionality of those APIs.
-
-The Lua API available to plugins is limited to the following calls::
-
-    assert  error   ipairs  next     pairs  tonumber
-    pcall   select  print   tostring type   xpcall
-    table   string  math    _VERSION
-
-It is not possible to e.g. use the ``io`` module from a script.
-
-To use methods on instantiated objects, the ``object:method`` method call
-syntax must be used. For example:
-
-.. code-block:: lua
-
-    libinput:register()
-    libinput.register() -- this will fail
-
-------------------------------------------------------------------------------
-When to use plugins
-------------------------------------------------------------------------------
-
-libinput plugins are a relatively niche use-case that typically need to
-address either once-off issues (e.g. those caused by worn-out hardware) or
-user preferences that libinput does not and will not cater for.
-
-Plugins should not be used for issues that can be fixed generically, for
-example via :ref:`device-quirks`.
-
-As a rule of thumb: a plugin should be a once-off that only works for one
-user's hardware. If a plugin can be shared with many users then the plugin
-implements functionality that should be integrated into libinput proper.
-
-------------------------------------------------------------------------------
-Testing plugins
-------------------------------------------------------------------------------
-
-Our :ref:`tools` support plugins if passed the ``--enable-plugins`` commandline
-option. For implementing and testing plugins the easiest commands to test are
-
-- ``libinput debug-events --enable-plugins`` (see :ref:`libinput-debug-events` docs)
-- ``libinput debug-gui --enable-plugins`` (see :ref:`libinput-debug-gui` docs)
-
-Where libinput is built and run from git, the tools will also look for plugins
-in the meson build directory. See the ``plugins/meson.build`` file for details.
-
-.. _plugins_api_lua:
-
---------------------------------------------------------------------------------
-Lua Plugin API
---------------------------------------------------------------------------------
-
-Lua plugins sit effectively below libinput and the API is not a
-representation of the libinput API. Plugins modify the evdev event stream
-received from the kernel.
-
-.. graphviz:: plugin-stack.gv
-
-The API revolves around two types: ``libinput`` and ``EvdevDevice``. The
-``libinput`` type is used to register a plugin from a script, the
-``EvdevDevice`` represents one device that is present in the system (but may
-not have yet been added by libinput).
-
-Typically a script does the following steps:
-
-- register with libinput via ``libinput:register({versions})``
-- connect to the ``"new-evdev-device"`` event
-- receive an ``EvdevDevice`` object in the ``"new-evdev-device"`` callback
-
-  - check and/or modify the evdev event codes on the device
-  - connect to the device's ``"evdev-frame"`` event
-
-- receive an :ref:`evdev frame <plugins_api_evdev_frame>` in the device's
-  ``"evdev-frame"`` callback
-
-  - check and/or modify the events in that frame
-
-Where multiple plugins are active, the evdev frame passed to the callback is
-the combined frame as processed by all previous plugins in ascending sort order.
-For example, if one plugin discards all button events subsequent plugins will
-never see those button events in the frame.
-
-.. _plugins_api_version_stability:
-
-..............................................................................
-Plugin version stability
-..............................................................................
-
-Plugin API version stability is provided on a best effort basis. We aim to provide
-stable plugin versions for as long as feasible but may need to retire some older
-versions over time. For this reason a plugin can select multiple versions it
-implements, libinput will pick one supported version and adjust the plugin
-behavior to match that version. See the ``libinput:register()`` call for details.
-
---------------------------------------------------------------------------------
-Lua Plugin API Reference
---------------------------------------------------------------------------------
-
-
-libinput provides the following globals and types:
-
-.. _plugins_api_evdev_usage:
-
-................................................................................
-Evdev Usages
-................................................................................
-
-Evdev usages are a libinput-specific wrapper around the ``linux/input-event-codes.h``
-evdev types and codes. They are used by libinput internally and are a 32-bit
-combination of ``type << 16 | code``. Each usage carries the type and code and
-is thus simpler to pass around and less prone to type confusion.
-
-The :ref:`evdev global <plugins_api_evdev_global>` attempts to provide all
-available usages but for the niche cases where it does not provide a named constant
-the value can be crafted manually:
-
-.. code-block:: lua
-
-   evdev_type = 0x3  -- EV_REL
-   evdev_code = 0x1  -- REL_Y
-   evdev_usage = (evdev_type << 16) | evdev_code
-
-   assert(usage == evdev.REL_Y)
-
-.. _plugins_api_evdev_global:
-
-................................................................................
-The ``evdev`` global
-................................................................................
-
-The ``evdev`` global represents all known :ref:`plugins_api_evdev_usage`,
-effectively in the form:
-
-.. code-block:: lua
-
-   evdev = {
-      ABS_X = (3 << 16) | 0,
-      ABS_Y = (3 << 16) | 1,
-      ...
-      REL_X = (2 << 16) | 0,
-      REL_Y = (2 << 16) | 1,
-      ...
-   }
-
-
-This global is provided for convenience to improve readability in the code.
-Note that the name uses the event code name only (e.g. ``evdev.ABS_Y``) but the
-value is an :ref:`Evdev Usage <plugins_api_evdev_usage>` (type and code).
-
-See the ``linux/input-event-codes.h`` header file provided by your kernel
-for a list of all evdev types and codes.
-
-The evdev global also provides the bus type constants, e.g. ``evdev.BUS_USB``.
-See the ``linux/input.h`` header file provided by your kernel
-for a list of bus types.
-
-
-.. _plugins_api_evdev_frame:
-
-................................................................................
-Evdev frames
-................................................................................
-
-Evdev frames represent a single frame of evdev events for a device. A frame
-is a group of events that occurred at the same time. The frame usually only
-contains state that has changed compared to the previous frame.
-
-In our API a frame is exposed as a nested table with the following structure:
-
-.. code-block:: lua
-
-    frame1 = {
-         { usage = evdev.ABS_X, value = 123 },
-         { usage = evdev.ABS_Y, value = 456 },
-         { usage = evdev.BTN_LEFT, value = 1 },
-    }
-    frame2 = {
-         { usage = evdev.ABS_Y, value = 457 },
-    }
-    frame3 = {
-         { usage = evdev.ABS_X, value = 124 },
-         { usage = evdev.BTN_LEFT, value = 0 },
-    }
-
-.. note:: This API does not use ``SYN_REPORT`` events, it is implied at the
-          end of the table. Where a plugin writes a ``SYN_REPORT`` into the
-          list of events, that ``SYN_REPORT`` terminates the event frame
-          (similar to writing a ``\0`` into the middle of a C string).
-          A frame containing only a ``SYN_REPORT`` is functionally equivalent
-          to an empty frame.
-
-Events or frames do not have a timestamp. Where a timestamp is required, that
-timestamp is passed as additional argument to the function or return value.
-
-See :ref:`plugins_api_evdev_global` for a list of known usages.
-
-.. warning:: Evdev frames have an implementation-defined size limit of how many
-             events can be added to a single frame. This limit should never be
-             hit by valid plugins.
-
-.. _plugins_api_libinputglobal:
-
-................................................................................
-The ``libinput`` global object
-................................................................................
-
-The core of our plugin API is the ``libinput`` global object. A script must
-immediately ``register()`` to be active, otherwise it is unloaded immediately.
-
-All libinput-specific APIs can be accessed through the ``libinput`` object.
-
-.. function:: libinput:register({1, 2, ...})
-
-   Register this plugin with the given table of supported version numbers and
-   returns the version number selected by libinput for this plugin. See
-   :ref:`plugins_api_version_stability` for details.
-
-   .. code-block:: lua
-
-       -- this plugin can support versions 1, 4 and 5
-       version = libinput:register({1, 4, 5})
-       if version == 1 then
-           ...
-
-   This function must be the first function called.
-   If the plugin calls any other functions before ``register()``, those functions
-   return the default zero value for the return type (``nil``, ``0``, an empty
-   table, etc.).
-
-   If the plugin does not call ``register()`` it will be removed immediately.
-   Once registered, any connected callbacks will be invoked whenever libinput
-   detects new devices, removes devices, etc.
-
-   This function must only be called once.
-
-.. function:: libinput:unregister()
-
-   Unregister this plugin. This removes the plugin from libinput and releases
-   any resources associated with this plugin. This call must be the last call
-   in your plugin, it is effectively equivalent to Lua's
-   `os.exit() <https://www.lua.org/manual/5.4/manual.html#pdf-os.exit>`_.
-
-.. function:: libinput:log_debug(message)
-
-   Log a message at the libinput debug log priority. See
-   ``libinput:log_error()`` for details.
-
-.. function:: libinput:log_info(message)
-
-   Log a message at the libinput info log priority. See
-   ``libinput:log_error()`` for details.
-
-.. function:: libinput:log_error(message)
-
-   Log a message at the libinput error log priority. Whether a message is
-   displayed in the log depends on libinput's log priority, set by the caller.
-
-   A compositor may disable stdout and stderr. Log messages should be preferred
-   over Lua's ``print()`` function to ensure the messages end up in the same
-   location as other libinput log messages and are not discarded.
-
-.. function:: libinput:now()
-
-   Returns the current time in microseconds in ``CLOCK_MONOTONIC``. This is
-   the timestamp libinput uses internally. This timestamp cannot be mapped
-   to any particular time of day, see the
-   `clock_gettime() man page <https://man7.org/linux/man-pages/man3/clock_gettime.3.html>`_
-   for details.
-
-.. function:: libinput:version()
-
-   Returns the agreed-on version of the plugin, see ``libinput:register()``.
-   If called before ``libinput:register()`` this function returns ``0``.
-
-.. function:: libinput:connect(name, function)
-
-   Set the callback to the given event name. Only one callback
-   may be set for an event name at any time, subsequent callbacks
-   will replace any earlier callbacks for the same name.
-
-   Version 1 of the plugin API supports the following events and callback arguments:
-
-   - ``"new-evdev-device"``: A new :ref:`EvdevDevice <plugins_api_evdevdevice>`
-     has been seen by libinput but not yet added.
-
-     .. code-block:: lua
-
-      libinput:connect("new-evdev-device", function (device) ... end)
-
-   - ``"timer-expired"``: The timer for this plugin has expired. This event is
-     only sent if the plugin has set a timer with ``timer_set()``.
-
-     .. code-block:: lua
-
-      libinput:connect("timer-expired", function (now) ... end)
-
-     The ``now`` argument is the current time in microseconds in
-     ``CLOCK_MONOTONIC`` (see ``libinput:now()``).
-
-.. function:: libinput:timer_cancel()
-
-   Cancel the timer for this plugin. This is a no-op if the timer
-   has not been set or has already expired.
-
-.. function:: libinput:timer_set_absolute(time)
-
-   Set a timer for this plugin, with the given time in microseconds.
-   The timeout specifies an absolute time in microseconds (see
-   ``libinput:now()``) The timer will expire once and then call the
-   ``"timer-expired"`` event handler (if any).
-
-   See ``libinput:timer_set_relative()`` for a relative timer.
-
-   The following two lines of code are equivalent:
-
-   .. code-block:: lua
-
-      libinput:timer_set_relative(1000000) -- 1 second from now
-      libinput:timer_set_absolute(libinput:now() + 1000000) -- 1 second from now
-
-   Calling this function will cancel any existing (relative or absolute) timer.
-
-.. function:: libinput:timer_set_relative(timeout)
-
-   Set a timer for this plugin, with the given timeout in microseconds from
-   the current time. The timer will expire once and then call the
-   ``"timer-expired"`` event handler (if any).
-
-   See ``libinput:timer_set_absolute()`` for an absolute timer.
-
-   The following two lines of code are equivalent:
-
-   .. code-block:: lua
-
-      libinput:timer_set_relative(1000000) -- 1 second from now
-      libinput:timer_set_absolute(libinput:now() + 1000000) -- 1 second from now
-
-   Calling this function will cancel any existing (relative or absolute) timer.
-
-.. _plugins_api_evdevdevice:
-
-................................................................................
-The ``EvdevDevice`` type
-................................................................................
-
-The ``EvdevDevice`` type represents a device available in the system
-but not (yet) added by libinput. This device may be used to modify
-a device's capabilities before the device is processed by libinput.
-
-A plugin should always ``connect()`` to the ``"device-removed"`` callback
-to be notified when a device is removed. If the plugin keeps a reference
-to this device but the device is discarded by libinput, the device's query
-methods will return zero values (e.g. ``nil``, ``0``, an empty table) and
-methods will be noops.
-
-.. function:: EvdevDevice:info()
-
-   A table containing static information about the device, e.g.
-
-   .. code-block:: lua
-
-      {
-         bustype = evdev.BUS_USB,
-         vid = 0x1234,
-         pid = 0x5678,
-      }
-
-   A plugin must ignore keys it does not know about.
-
-   Version 1 of the plugin API supports the following keys and values:
-
-   - ``bustype``: The numeric bustype of the device. See the
-     ``BUS_*`` defines in ``linux/input.h`` for the list of possible values.
-   - ``vid``: The 16-bit vendor ID of the device
-   - ``pid``: The 16-bit product ID of the device
-
-   If the device has since been discarded by libinput, this function returns an
-   empty table.
-
-.. function:: EvdevDevice:name()
-
-   The device name as set by the kernel
-
-.. function:: EvdevDevice:usages()
-
-   Returns a table of all usages that are currently enabled for this
-   device. Any type that exists on the device has a table assigned and in this
-   table any code that exists on the device is a boolean true.
-   For example:
-
-   .. code-block:: lua
-
-      {
-         evdev.REL_X = true,
-         evdev.REL_Y = true,
-         evdev.BTN_LEFT = true,
-      }
-
-   All other usages are ``nil``, so that the following code is possible:
-
-   .. code-block:: lua
-
-      local usages = device:usages()
-      if usages[evdev.REL_X] then
-         -- do something
-      end
-
-
-   If the device has since been discarded by libinput, this function returns an
-   empty table.
-
-.. function:: EvdevDevice:absinfos()
-
-   Returns a table of all ``EV_ABS`` codes that are currently enabled for this device.
-   The event code is the key, each value is a table containing the following keys:
-   ``minimum``, ``maximum``, ``fuzz``, ``flat``, ``resolution``.
-
-   .. code-block:: lua
-
-      {
-         evdev.ABS_X = {
-            minimum = 0,
-            maximum = 1234,
-            fuzz = 0,
-            flat = 0,
-            resolution = 45,
-         },
-      }
-
-   If the device has since been discarded by libinput, this function returns an
-   empty table.
-
-.. function:: EvdevDevice:udev_properties()
-
-   Returns a table containing a filtered list of udev properties available on this device
-   in the form ``{ property_name = property_value, ... }``.
-   udev properties used as a boolean (e.g. ``ID_INPUT``) are only present if their
-   value is a logical true.
-
-   Version 1 of the plugin API supports the following udev properties:
-
-   - ``ID_INPUT`` and all of ``ID_INPUT_*`` that denote the device type as assigned
-     by udev. This information is usually used by libinput to determine a
-     device type. Note that for historical reasons these properties have
-     varying rules - some properties may be mutually exclusive, others are
-     independent, others may only be set if another property is set. Refer to
-     the udev documentation (if any) for details. ``ID_INPUT_WIDTH_MM`` and
-     ``ID_INPUT_HEIGHT_MM`` are excluded from this set.
-
-   If the device has since been discarded by libinput, this function returns an
-   empty table.
-
-.. function:: EvdevDevice:enable_evdev_usage(usage)
-
-   Enable the given :ref:`evdev usage <plugins_api_evdev_usage>` for this device.
-   Use :ref:`plugins_api_evdev_global` for better readability,
-   e.g. ``device:enable_evdev_usage(evdev.REL_X)``.
-   This function must not be used for ``ABS_*`` events, use ``set_absinfo()``
-   instead.
-
-   Once a usage is enabled, events for that usage may be added to a device's
-   frame.
-
-   If the device has since been discarded by libinput, this function does nothing.
-
-.. function:: EvdevDevice:disable_evdev_usage(usage)
-
-   Disable the given :ref:`evdev usage <plugins_api_evdev_usage>` for this device.
-   Use :ref:`plugins_api_evdev_global` for better readability,
-   e.g. ``device:disable_evdev_usage(evdev.REL_X)``.
-
-   Once a usage is disabled, events for that usage are discarded from any
-   device frame.
-
-   If the device has since been discarded by libinput, this function does nothing.
-
-.. function:: EvdevDevice:set_absinfo(usage, absinfo)
-
-   Set the absolute axis information for the given :ref:`evdev usage <plugins_api_evdev_usage>`
-   and enable it if it does not yet exist on the device. The ``absinfo`` argument is a table
-   containing zero or more of the following keys: ``minimum``, ``maximum``, ``fuzz``,
-   ``flat``, ``resolution``. Any missing key defaults the corresponding
-   value from the device if the device already has this event usage or zero otherwise.
-   For example, the following code changes the resolution but leaves everything
-   else as-is:
-
-   .. code-block:: lua
-
-      local absinfo = {
-         resolution = 40,
-      }
-      device:set_absinfo(evdev.ABS_X, absinfo)
-      device:set_absinfo(evdev.ABS_Y, absinfo)
-
-   Use :ref:`plugins_api_evdev_global` for better readability as shown in the
-   example above.
-
-   If the device has since been discarded by libinput, this function does nothing.
-
-   .. note:: Overriding the absinfo values often indicates buggy firmware. This should
-             typically be fixed with an entry in the
-             `60-evdev.hwdb <https://github.com/systemd/systemd/blob/main/hwdb.d/60-evdev.hwdb>`_
-             or :ref:`device-quirks` instead of a plugin so all users of that
-             device can benefit from the fix.
-
-.. function:: EvdevDevice:connect(name, function)
-
-   Set the callback to the given event name. Only one callback
-   may be set for an event name at any time, subsequent callbacks
-   will overwrite any earlier callbacks for the same name.
-
-   If the device has since been discarded by libinput, this function does nothing.
-
-   Version 1 of the plugin API supports the following events and callback arguments:
-
-   - ``"evdev-frame"``: A new :ref:`evdev frame <plugins_api_evdev_frame>` has
-     started for this device. If the callback returns a value other than
-     ``nil``, that value is the frame with any modified events.
-     An empty frame (``{}``) causes libinput to drop the current event frame.
-
-     .. code-block:: lua
-
-        device:connect("evdev-frame", function (device, frame, timestamp)
-            -- change any event into a movement left by 1 pixel
-            move_left = {
-                  { usage = evdev.REL_X, value = -1, },
-            }
-            return move_left
-        end
-
-     The timestamp of an event frame is in microseconds in ``CLOCK_MONOTONIC``, see
-     ``libinput:now()`` for details.
-
-     For performance reasons plugins that do not modify the event frame should
-     return ``nil`` (or nothing) instead of the event frame that was passed
-     as argument.
-
-   - ``"device-removed"``: This device was removed by libinput. This may happen
-     without the device ever becoming a libinput device as seen by libinput's
-     public API (e.g. if the device does not meet the requirements to be
-     added). Once this callback is invoked, the plugin should remove any
-     references to this device and stop using it.
-
-     .. code-block:: lua
-
-      device:connect("device-removed", function (device) ... end)
-
-     Functions to query the device's capabilities (e.g. ``usages()``) will
-     return an empty table.
-
-.. function:: EvdevDevice:disconnect(name)
-
-   Disconnect the existing callback (if any) for the given event name. See
-   ``EvdevDevice:connect()`` for a list of supported names.
-
-.. function:: EvdevDevice:prepend_frame(frame)
-
-   Prepend an :ref:`evdev frame <plugins_api_evdev_frame>` for this device
-   **before** the current frame (if any). The **next** plugin will see the
-   prepended frame first followed by the current frame.
-
-   This function can only be called from within a device's ``"evdev-frame"``
-   handler or from within the plugin's timer callback function.
-
-   For example, to change a single event into a drag, prepend a button
-   down and append a button up before each event:
-
-   .. code:: lua
-
-      function frame_handler(device, frame, timestamp)
-          device:prepend_frame({

-
-==============================================================================
-Middle button emulation
-==============================================================================
-
-Middle button emulation provides users with the ability to generate a middle
-click even when the device does not have a physical middle button available.
-
-When middle button emulation is enabled, a simultaneous press of the left
-and right button generates a middle mouse button event. Releasing the
-buttons generates a middle mouse button release, the left and right button
-events are discarded otherwise.
-
-The middle button release event may be generated when either button is
-released, or when both buttons have been released. The exact behavior is
-device-dependent, libinput will implement the behavior that is most
-appropriate to the physical device.
-
-The middle button emulation behavior when combined with other device
-buttons, including a physical middle button is device-dependent.
-For example, :ref:`clickpad_softbuttons` provides a middle button area when
-middle button emulation is disabled. That middle button area disappears
-when middle button emulation is enabled - a middle click can then only be
-triggered by a simultaneous left + right click.
-
-Some devices provide middle mouse button emulation but do not allow
-enabling/disabling that emulation. Likewise, some devices may allow middle
-button emulation but have it disabled by default. This is the case for most
-mouse-like devices where a middle button is detected.
-
-libinput provides **libinput_device_config_middle_emulation_set_enabled()** to
-enable or disable middle button emulation. See :ref:`faq_configure_wayland`
-and :ref:`faq_configure_xorg` for info on how to enable or disable middle
-button emulation in the Wayland compositor or the X stack.

-.. _motion_normalization:
-
-==============================================================================
-Normalization of relative motion
-==============================================================================
-
-Most relative input devices generate input in so-called "mickeys". A
-mickey is in device-specific units that depend on the resolution
-of the sensor. Most optical mice use sensors with 1000dpi resolution, but
-some devices range from 100dpi to well above 8000dpi.
-
-Without a physical reference point, a relative coordinate cannot be
-interpreted correctly. A delta of 10 mickeys may be a millimeter of
-physical movement or 10 millimeters, depending on the sensor. This
-affects pointer acceleration in libinput and interpretation of relative
-coordinates in callers.
-
-libinput does partial normalization of relative input. For devices with a
-resolution of 1000dpi and higher, motion events are normalized to a default
-of 1000dpi before pointer acceleration is applied. As a result, devices with
-1000dpi and above feel the same.
-
-Devices below 1000dpi are not normalized (normalization of a 1-device unit
-movement on a 400dpi mouse would cause a 2.5 pixel movement). Instead,
-libinput applies a dpi-dependent acceleration function. At low speeds, a
-1-device unit movement usually translates into a 1-pixel movements. As the
-movement speed increases, acceleration is applied - at high speeds a low-dpi
-device will roughly feel the same as a higher-dpi mouse.
-
-The reason for the normalization is convenience: a caller can assume that a
-delta of 1 should result in a movement of 1 pixel on a traditional
-(low-dpi) screen. On screens with high resolutions, the caller must scale
-according to the UI scale factors.
-
-This normalization only applies to accelerated coordinates, unaccelerated
-coordinates are left in device-units. It is up to the caller to interpret
-those coordinates correctly.
-
-.. _motion_normalization_touchpad:
-
-------------------------------------------------------------------------------
-Normalization of touchpad coordinates
-------------------------------------------------------------------------------
-
-Touchpads may have a different resolution for the horizontal and vertical
-axis. Interpreting coordinates from the touchpad without taking resolution
-into account results in uneven motion.
-
-libinput scales unaccelerated touchpad motion to the resolution of the
-touchpad's x axis, i.e. the unaccelerated value for the y axis is:
-``y = (x / resolution_x) * resolution_y``.

-
-.. _motion_normalization_customization:
-
-------------------------------------------------------------------------------
-Setting custom DPI settings
-------------------------------------------------------------------------------
-
-Devices usually do not advertise their resolution and libinput relies on
-the udev property **MOUSE_DPI** for this information. This property is usually
-set via the
-`udev hwdb <http://cgit.freedesktop.org/systemd/systemd/tree/hwdb/70-mouse.hwdb>`_.
-The ``mouse-dpi-tool`` utility provided by
-`libevdev <https://freedesktop.org/wiki/Software/libevdev/>`_ should be
-used to measure a device's resolution.
-
-The format of the property for single-resolution mice is: ::
-
-          MOUSE_DPI=resolution@frequency
-
-The resolution is in dots per inch, the frequency in Hz.
-The format of the property for multi-resolution mice may list multiple
-resolutions and frequencies: ::
-
-          MOUSE_DPI=r1@f1 *r2@f2 r3@f3
-
-The default frequency must be pre-fixed with an asterisk.
-
-For example, these two properties are valid: ::
-
-          MOUSE_DPI=800@125
-          MOUSE_DPI=400@125 800@125 *1000@500 5500@500
-
-The behavior for a malformed property is undefined. If the property is
-unset, libinput assumes the resolution is 1000dpi.
-
-Note that HW does not usually provide information about run-time
-resolution changes, libinput will thus not detect when a resolution
-changes to the non-default value.

-.. _palm_detection:
-
-==============================================================================
-Palm detection
-==============================================================================
-
-Palm detection tries to identify accidental touches while typing, while
-using the trackpoint and/or during general use of the touchpad area.
-
-On most laptops typing on the keyboard generates accidental touches on the
-touchpad with the palm (usually the area below the thumb). This can lead to
-cursor jumps or accidental clicks. On large touchpads, the palm may also
-touch the bottom edges of the touchpad during normal interaction.
-
-Interference from a palm depends on the size of the touchpad and the position
-of the user's hand. Data from touchpads showed that almost all palm events
-during typing on a Lenovo T440 happened in the left-most and right-most 5% of
-the touchpad. The T440 series has one of the largest touchpads, other
-touchpads are less affected by palm touches.
-
-libinput has multiple ways of detecting a palm, each of which depends on
-hardware-specific capabilities.

-- :ref:`disable-while-trackpointing`
-- :ref:`stylus-touch-arbitration`
-
-Palm detection is always enabled, with the exception of
-disable-while-typing.
-
-.. _palm_tool:
-
-------------------------------------------------------------------------------
-Palm detection based on firmware labelling
-------------------------------------------------------------------------------
-
-Some devices provide palm detection in the firmware, forwarded by the kernel
-as the ``EV_ABS/ABS_MT_TOOL`` axis with a value of ``MT_TOOL_PALM``
-(whenever a palm is detected). libinput honors that value and switches that
-touch to a palm.
-
-.. _palm_pressure:
-
-------------------------------------------------------------------------------
-Palm detection based on pressure
-------------------------------------------------------------------------------
-
-The simplest form of palm detection labels a touch as palm when the pressure
-value goes above a certain threshold. This threshold is usually high enough
-that it cannot be triggered by a finger movement. Once a touch is labelled as
-palm based on pressure, it will remain so even if the pressure drops below
-the threshold again. This ensures that a palm remains a palm even when the
-pressure changes as the user is typing.
-
-For some information on how to detect pressure on a touch and debug the
-pressure ranges, see :ref:`touchpad_pressure`.
-
-.. _palm_touch_size:
-
-------------------------------------------------------------------------------
-Palm detection based on touch size
-------------------------------------------------------------------------------
-
-On touchpads that support the ``ABS_MT_TOUCH_MAJOR`` axes, libinput can perform
-palm detection based on the size of the touch ellipse. This works similar to
-the pressure-based palm detection in that a touch is labelled as palm when
-it exceeds the (device-specific) touch size threshold.
-
-For some information on how to detect the size of a touch and debug the
-touch size ranges, see :ref:`touchpad_pressure`.
-
-.. _palm_exclusion_zones:
-
-------------------------------------------------------------------------------
-Palm exclusion zones
-------------------------------------------------------------------------------
-
-libinput enables palm detection on the left, right and top edges of the
-touchpad. Two exclusion zones are defined  on the left and right edge of the
-touchpad. If a touch starts in the exclusion zone, it is considered a palm
-and the touch point is ignored. However, for fast cursor movements across
-the screen, it is common for a finger to start inside an exclusion zone and
-move rapidly across the touchpad. libinput detects such movements and avoids
-palm detection on such touch sequences.
-
-Another exclusion zone is defined on the top edge of the touchpad. As with
-the edge zones, libinput detects vertical movements out of the edge zone and
-avoids palm detection on such touch sequences.
-
-A touch starting in the exclusion zone does not trigger a tap (see
-:ref:`tapping`).
-
-In the diagram below, the exclusion zones are painted red.
-Touch 'A' starts inside the exclusion zone and moves
-almost vertically. It is considered a palm and ignored for cursor movement,
-despite moving out of the exclusion zone.
-
-Touch 'B' starts inside the exclusion zone but moves horizontally out of the
-zone. It is considered a valid touch and controls the cursor.
-
-Touch 'C' occurs in the exclusion zone. Despite being a tapping motion, it does
-not generate an emulated button event.

-
-.. _trackpoint-disabling:
-
-------------------------------------------------------------------------------
-Palm detection during trackpoint use
-------------------------------------------------------------------------------
-
-If a device provides a
-`trackpoint <http://en.wikipedia.org/wiki/Pointing_stick>`_, it is
-usually located above the touchpad. This increases the likelihood of
-accidental touches whenever the trackpoint is used.
-
-libinput disables the touchpad whenever it detects trackpoint activity for a
-certain timeout until after trackpoint activity stops. Touches generated
-during this timeout will not move the pointer, and touches started during
-this timeout will likewise not move the pointer (allowing for a user to rest
-the palm on the touchpad while using the trackstick).
-If the touchpad is disabled, the :ref:`top software buttons <t440_support>`
-remain enabled.
-
-.. _disable-while-typing:
-
-------------------------------------------------------------------------------
-Disable-while-typing
-------------------------------------------------------------------------------
-
-libinput automatically disables the touchpad for a timeout after a key
-press, a feature traditionally referred to as "disable while typing" and
-previously available through the
-`syndaemon(1) <http://linux.die.net/man/1/syndaemon>`_ command. libinput does
-not require an external command and the feature is currently enabled for all
-touchpads but will be reduced in the future to only apply to touchpads where
-finger width or pressure data is unreliable.
-
-Notable behaviors of libinput's disable-while-typing feature:
-
-- Two different timeouts are used, after a single key press the timeout is
-  short to ensure responsiveness. After multiple key events, the timeout is
-  longer to avoid accidental pointer manipulation while typing.
-- Some keys do not trigger the timeout, specifically some modifier keys
-  (Ctrl, Alt, Shift, and Fn). Actions such as Ctrl + click thus stay
-  responsive.
-- Touches started while typing do not control the cursor even after typing
-  has stopped, it is thus possible to rest the palm on the touchpad while
-  typing.
-- Physical buttons work even while the touchpad is disabled. This includes
-  :ref:`software-emulated buttons <t440_support>`.
-- libinput pairs touchpads and keyboards for the disable-while-typing
-  feature. In the most common case, the internal touchpad is paired only
-  with the internal keyboard. Typing on an external keyboard will thus not
-  disable the touchpad. Some devices require a :ref:`quirk <device-quirks>`
-  to be correctly paired.
-
-Disable-while-typing can be enabled and disabled by calling
-**libinput_device_config_dwt_set_enabled()**.
-
-.. _disable-while-trackpointing:
-
-------------------------------------------------------------------------------
-Disable-while-trackpointing
-------------------------------------------------------------------------------
-
-libinput automatically disables the touchpad for a timeout after the trackpoint
-is moved, a feature referred to as "disable while trackpointing". libinput does
-not require an external command and the feature is currently enabled for all
-touchpads.
-
-Disable-while-trackpointing can be enabled and disabled by calling
-**libinput_device_config_dwtp_set_enabled()**.
-
-.. _stylus-touch-arbitration:
-
-------------------------------------------------------------------------------
-Stylus-touch arbitration
-------------------------------------------------------------------------------
-
-A special case of palm detection is touch arbitration on devices that
-support styli. When interacting with a stylus on the screen, parts of the
-hand may touch the surface and trigger touches. As the user is currently
-interacting with the stylus, these touches would interfere with the correct
-working of the stylus.
-
-libinput employs a method similar to :ref:`disable-while-typing` to detect
-these touches and disables the touchpad accordingly.
-
-.. _thumb-detection:
-
-------------------------------------------------------------------------------
-Thumb detection
-------------------------------------------------------------------------------
-
-Many users rest their thumb on the touchpad while using the index finger to
-move the finger around. For clicks, often the thumb is used rather than the
-finger. The thumb should otherwise be ignored as a touch, i.e. it should not
-count towards :ref:`clickfinger` and it should not cause a single-finger
-movement to trigger :ref:`twofinger_scrolling`.
-
-libinput uses two triggers for thumb detection: pressure and
-location. A touch exceeding a pressure threshold is considered a thumb if it
-is within the thumb detection zone.
-
-.. note:: "Pressure" on touchpads is synonymous with "contact area." A large touch
-	surface area has a higher pressure and thus hints at a thumb or palm
-	touching the surface.
-
-Pressure readings are unreliable at the far bottom of the touchpad as a
-thumb hanging mostly off the touchpad will have a small surface area.
-libinput has a definitive thumb zone where any touch is considered a resting
-thumb.
-
-.. figure:: thumb-detection.svg
-    :align: center
-

-.. _pointer-acceleration:
-
-==============================================================================
- Pointer acceleration
-==============================================================================
-
-libinput uses device-specific pointer acceleration methods, with the default
-being the :ref:`ptraccel-linear`. The methods share common properties, such as
-:ref:`ptraccel-velocity`.
-
-This page explains the high-level concepts used in the code. It aims to
-provide an overview for developers and is not necessarily useful for
-users.
-
-.. _ptraccel-profiles:
-
-------------------------------------------------------------------------------
-Pointer acceleration profiles
-------------------------------------------------------------------------------
-
-The profile decides the general method of pointer acceleration.
-libinput currently supports three profiles: **"adaptive"**, **"flat"** and
-**"custom"**.
-
-- The **adaptive** profile is the default profile for all devices and takes the
-  current speed of the device into account when deciding on acceleration.
-- The **flat** profile is simply a constant factor applied to all device deltas,
-  regardless of the speed of motion (see :ref:`ptraccel-profile-flat`).
-- The **custom** profile allows the user to define a custom acceleration
-  function, giving full control over accelerations behavior at different speed
-  (see :ref:`ptraccel-profile-custom`).
-
-Most of this document describes the adaptive pointer acceleration.
-
-.. _ptraccel-velocity:
-
-------------------------------------------------------------------------------
-Velocity calculation
-------------------------------------------------------------------------------
-
-The device's speed of movement is measured across multiple input events
-through so-called "trackers". Each event prepends a tracker item, each
-subsequent tracker contains the delta of that item to the current position,
-the timestamp of the event that created it and the cardinal direction of the
-movement at the time. If a device moves into the same direction, the
-velocity is calculated across multiple trackers. For example, if a device
-moves steadily for 10 events to the left, the velocity is calculated across
-all 10 events.
-
-Whenever the movement changes direction or significantly changes speed, the
-velocity is calculated from the direction/speed change only. For example, if
-a device moves steadily for 8 events to the left and then 2 events to the
-right, the velocity is only that of the last 2 events.
-
-An extra time limit prevents events that are too old to factor into the
-velocity calculation. For example, if a device moves steadily for 5 events
-to the left, then pauses, then moves again for 5 events to the left, only
-the last 5 events are used for velocity calculation.
-
-The velocity is then used to calculate the acceleration factor
-
-.. _ptraccel-factor:
-
-------------------------------------------------------------------------------
-Acceleration factor
-------------------------------------------------------------------------------
-
-The acceleration factor is the final outcome of the pointer acceleration
-calculations. It is a unitless factor that is applied to the current delta,
-a factor of 2 doubles the delta (i.e. speeds up the movement), a factor of
-less than 1 reduces the delta (i.e. slows the movement).
-
-Any factor less than 1 requires the user to move the device further to move
-the visible pointer. This is called deceleration and enables high precision
-target selection through subpixel movements. libinput's current maximum
-deceleration factor is 0.3 (i.e. slow down to 30% of the pointer speed).
-
-A factor higher than 1 moves the pointer further than the physical device
-moves. This is acceleration and allows a user to cross the screen quickly
-but effectively skips pixels. libinput's current maximum acceleration factor
-is 3.5.
-
-.. _ptraccel-linear:
-
-------------------------------------------------------------------------------
-Linear pointer acceleration
-------------------------------------------------------------------------------
-
-The linear pointer acceleration method is the default for most pointer
-devices. It provides deceleration at very slow movements, a 1:1 mapping for
-regular movements and a linear increase to the maximum acceleration factor
-for fast movements.
-
-Linear pointer acceleration applies to devices with above 1000dpi resolution
-and after :ref:`motion_normalization` is applied.
-
-.. figure:: ptraccel-linear.svg
-    :align: center
-
-    Linear pointer acceleration
-
-The image above shows the linear pointer acceleration settings at various
-speeds. The line for 0.0 is the default acceleration curve, speed settings
-above 0.0 accelerate sooner, faster and to a higher maximum acceleration.
-Speed settings below 0 delay when acceleration kicks in, how soon the
-maximum acceleration is reached and the maximum acceleration factor.
-
-Extremely low speed settings provide no acceleration and additionally
-decelerate all movement by a constant factor.
-
-.. _ptraccel-low-dpi:
-
-------------------------------------------------------------------------------
-Pointer acceleration for low-dpi devices
-------------------------------------------------------------------------------
-
-Low-dpi devices are those with a physical resolution of less than 1000 dots
-per inch (dpi). The pointer acceleration is adjusted to provide roughly the
-same feel for all devices at normal to high speeds. At slow speeds, the
-pointer acceleration works on device-units rather than normalized
-coordinates (see :ref:`motion_normalization`).
-
-.. figure:: ptraccel-low-dpi.svg
-    :align: center
-
-    Pointer acceleration for low-dpi devices
-
-The image above shows the default pointer acceleration curve for a speed of
-0.0 at different DPI settings. A device with low DPI has the acceleration
-applied sooner and with a stronger acceleration factor.
-
-.. _ptraccel-touchpad:
-
-------------------------------------------------------------------------------
-Pointer acceleration on touchpads
-------------------------------------------------------------------------------
-
-Touchpad pointer acceleration uses the same approach as the
-:ref:`ptraccel-linear` profile, with a constant deceleration factor applied. The
-user expectation of how much a pointer should move in response to finger
-movement is different to that of a mouse device, hence the constant
-deceleration factor.
-
-.. figure:: ptraccel-touchpad.svg
-    :align: center
-
-    Pointer acceleration curve for touchpads
-
-The image above shows the touchpad acceleration profile in comparison to the
-:ref:`ptraccel-linear`. The shape of the curve is identical but vertically squashed.
-
-.. _ptraccel-trackpoint:
-
-------------------------------------------------------------------------------
-Pointer acceleration on trackpoints
-------------------------------------------------------------------------------
-
-The main difference between trackpoint hardware and mice or touchpads is
-that trackpoint speed is a function of pressure rather than moving speed.
-But trackpoint hardware is quite varied in how it reacts to user pressure
-and unlike other devices it cannot easily be normalized for physical
-properties. Measuring pressure objectively across a variety of hardware is
-nontrivial. See :ref:`trackpoints` for more details.
-
-The deltas for trackpoints are converted units/ms but there is no common
-physical reference point for a unit. Thus, the same pressure on different
-trackpoints will generate different speeds and thus different acceleration
-behaviors. Additionally, some trackpoints provide the ability to adjust the
-sensitivity in hardware by modifying a sysfs file on the serio node. A
-higher sensitivity results in higher deltas, thus changing the definition of
-what is a unit again.
-
-libinput attempts to normalize unit data to the best of its abilities, see
-:ref:`trackpoint_multiplier`. Beyond this, it is not possible to have
-consistent behavior across different trackpoint devices.
-
-.. figure:: ptraccel-trackpoint.svg
-    :align: center
-
-    Pointer acceleration curves for trackpoints
-
-The image above shows the trackpoint acceleration profile for the speed in
-units/ms.
-
-.. _ptraccel-profile-flat:
-
-------------------------------------------------------------------------------
-The flat pointer acceleration profile
-------------------------------------------------------------------------------
-
-In a flat profile, the acceleration factor is constant regardless of the
-velocity of the pointer and each delta (dx, dy) results in an accelerated delta
-(dx * factor, dy * factor). This provides 1:1 movement between the device
-and the pointer on-screen.
-
-.. _ptraccel-tablet:
-
-------------------------------------------------------------------------------
-Pointer acceleration on tablets
-------------------------------------------------------------------------------
-
-Pointer acceleration for relative motion on tablet devices is a flat
-acceleration, with the speed setting slowing down or speeding up the pointer
-motion by a constant factor. Tablets do not allow for switchable profiles.
-
-.. _ptraccel-profile-custom:
-
-------------------------------------------------------------------------------
-The custom acceleration profile
-------------------------------------------------------------------------------
-
-libinput supports a user-defined custom acceleration profile, which can be
-adjusted for different movement types supported by a device. Movement types
-include pointer movement, scrolling, etc. but the set of supported
-movement types depends on the device.
-
-The custom pointer acceleration profile gives users full control over the
-acceleration behavior at different speeds. libinput exposes
-an acceleration function ``f(x)`` where the x axis is the device speed in
-device units per millisecond and the y axis is the pointer speed. By
-supplying the y axis values for this function, users can control the
-behavior of the device.
-
-The user should take into account the native device dpi and screen dpi in
-order to achieve the desired behavior/feel.
-
-The custom acceleration function is defined using ``n`` points which are spaced
-uniformly along the x axis, starting from 0 and continuing in constant steps.
-At least two points must be defined and there is an implementation-defined
-limit on how many points may be added.
-
-Thus the points defining the custom function are:
-``(0 * step, f[0]), (1 * step, f[1]), ..., ((n-1) * step, f[n-1])``
-where ``f`` is a list of ``n`` values defining the output velocity for each
-input velocity.
-The acceleration factor is defined by the ratio of the output velocity to the
-input velocity.
-When a velocity value does not lie exactly on those points, a linear
-interpolation of the two closest points will be calculated.
-When a velocity value is greater than the max point defined, a linear
-extrapolation of the two biggest points will be calculated.
-
-the calculation made by libinput: ::
-
-    input_delta = device delta units
-    delta_time = time in ms since last input_delta
-    input_speed = hypot(input_delta) / delta_time
-    output_speed = user_custom_function(input_speed)
-    acceleration_factor = output_speed / input_speed
-    output_delta = input_delta * acceleration_factor
-
-An example is the curve of ``0.0, 1.0`` with a step of ``1.0``. This curve
-is the equivalent of the flat acceleration profile with any input speed ``N``
-mapped to the same pointer speed ``N``. The curve ``1.0, 1.0`` neutralizes
-any input speed differences and results in a fixed pointer speed.
-
-Another example is the custom acceleration function ``x**2``,
-sampling the function at ``4`` points up to
-a maximum input speed of ``9`` will give us a custom function with
-a step of ``3`` and points ``[0.0, 9.0, 36.0, 81.0]``:
-
-.. figure:: ptraccel-custom.svg
-    :align: center
-
-More sampled points can be added to improve the accuracy of the user custom
-function.
-
-Supported Movement types:
-
-+---------------+---------------------------------+----------------------+
-| Movement type | Uses                            | supported by         |
-+===============+=================================+======================+
-| Fallback      | Catch-all default movement type | All devices          |
-+---------------+---------------------------------+----------------------+
-| Motion        | Used for pointer motion         | All devices          |
-+---------------+---------------------------------+----------------------+
-| Scroll        | Used for scroll movement        | Mouse, Touchpad      |
-+---------------+---------------------------------+----------------------+
-
-If a user does not provide the fallback custom acceleration function, a
-flat acceleration function is used, i.e. no acceleration.
-
-The fallback acceleration may be used for different types of movements, it is
-strongly recommended that this acceleration function is a constant function.
-
-For example, a touchpad has multiple movement types: pointer
-movement, scroll movement, zoom movement (pinch), etc. As there is no separate
-movement type for zoom yet, zoom movement is accelerated using the Fallback
-acceleration function. Pointer movement is accelerated using the Motion
-acceleration function, and Scroll movement is accelerated using the Scroll
-acceleration function. If no Motion/Scroll acceleration function is set, the
-Fallback acceleration function is used.
-
-When using custom acceleration profile, any calls to set the speed have no
-effect on the behavior of the custom acceleration function, but any future calls to
-get the speed will reflect the requested speed setting.

-Reproducing bugs
-------------------------------------------------------------------------------
-
-Try to identify the bug by reproducing it reliably. Bugs without a
-reliable reproducer will have lowest priority. The more specific a bug
-description and reproducer is, the easier it is to fix.
-
-Try to replicate the series of events that lead to the bug being triggered.
-Narrow it down until you have a reliable sequence that can trigger the bug.
-For the vast majority of bugs you should not take longer than 5 seconds or
-three interactions (clicks, touches, taps, ...) with the device to
-reproduce. If it takes longer than that, you can narrow it down further.
-
-Once you can reproduce it, use the :ref:`libinput-debug-events` helper
-tool::
-
- $> libinput debug-events --verbose
-
-The output is textual and can help identify whether the bug is in libinput
-at all. Note that any configuration options you have set must be specified
-on the commandline, see the :ref:`libinput-debug-events`
-man page. Use the ``--verbose`` flag to get more information about how
-libinput processes events.
-
-If the bug cannot be reproduced with the :ref:`libinput-debug-events` helper,

-.. _fixed_bugs:
-
-------------------------------------------------------------------------------
-My bug was closed as fixed, what now?
-------------------------------------------------------------------------------
-
-libinput's policy on closing bugs is: once the fix for a given bug is on git
-master, the bug is considered fixed and the gitlab issue will be closed
-accordingly.
-
-Of course, unless you actually run git master, the bug will continue to
-affect you on your local machine. You are most likely running the
-distribution's package and you will need to wait until the distribution has
-updated its package accordingly.
-
-.. warning:: Do not re-open a bug just because it hasn't trickled down to
-             your distribution's package version yet.
-
-Whether the bug fix ends up in your distribution depends on a number of
-things. Any given bug fix **may** be cherry-picked into the current stable
-branch, depending on its severity, impact, and likelihood to cause
-regressions. Once cherry-picked it will land in the next stable branch
-release. These are usually a few weeks apart.
-
-.. warning:: Do not re-open a bug because it wasn't picked into a stable branch
-             release or because your distribution didn't update to the latest stable
-             branch release.
-
-Stable branches are usually discontinued when the next release comes out.
-
-Your distribution may pick a patch up immediately and ship the fix
-even before the next stable branch update is released. For example, Fedora
-does this frequently.
-
-.. hint:: If a bug needs to be fixed urgently, file a bug in your
-          distribution's bug tracker.
-
-Patches on git master will end up in the next libinput release. Once your
-distribution updates to that release, your local libinput version will
-contain the fix.
-
-.. warning:: Do not re-open a bug because your distribution didn't update to
-             the release.
-
-You can always run libinput from git master (see :ref:`building_libinput`).
-Even while in development, libinput is very stable so this option isn't as
-scary as it may sounds.
-
-.. _reporting_bugs_reopen:
-
-..............................................................................
-When is it ok to re-open a fixed bug?
-..............................................................................
-
-Any time the bug was considered fixed but it turns out that the fix is
-insufficient and/or causes a regression.
-
-However, if the regression is in behavior unrelated to the fix itself it is
-usually better to file a new bug to reduce the noise. For example, if a fix
-to improve tapping breaks two-finger scrolling behavior, you should file a
-new bug but reference the original bug.
-
-.. _reporting_bugs_tags:
-
-------------------------------------------------------------------------------
-Gitlab issue tracker tags
-------------------------------------------------------------------------------
-
-The gitlab issue tracker allows developers to add tags to bugs to classify
-them.
-
-- **being worked on**: someone is currently working on this feature. This
-  tag is used for features that will take a long time to implement fully and
-  prevents others from having to duplicate the work. Do reach out and ask if
-  help and/or further testing is needed.
-- **bug**: issue is confirmed to be a bug

-.. _scrolling:
-
-==============================================================================
-Scrolling
-==============================================================================
-
-libinput supports three different types of scrolling methods:
-:ref:`twofinger_scrolling`, :ref:`edge_scrolling` and
-:ref:`button_scrolling`. Some devices support multiple methods, though only
-one can be enabled at a time. As a general overview:
-
-- touchpad devices with physical buttons below the touchpad support edge and
-  two-finger scrolling
-- touchpad devices without physical buttons (:ref:`ClickPads <clickpad_softbuttons>`)
-  support two-finger scrolling only
-- pointing sticks provide on-button scrolling by default
-- mice and other pointing devices support on-button scrolling but it is not
-  enabled by default
-
-A device may differ from the above based on its capabilities. See
-**libinput_device_config_scroll_set_method()** for documentation on how to
-switch methods and **libinput_device_config_scroll_get_methods()** for
-documentation on how to query a device for available scroll methods.
-
-.. _horizontal_scrolling:
-
-------------------------------------------------------------------------------
-Horizontal scrolling
-------------------------------------------------------------------------------
-
-Scroll movements provide vertical and horizontal directions, each
-scroll event contains both directions where applicable, see
-**libinput_event_pointer_get_axis_value()**. libinput does not provide separate
-toggles to enable or disable horizontal scrolling. Instead, horizontal
-scrolling is always enabled. This is intentional, libinput does not have
-enough context to know when horizontal scrolling is appropriate for a given
-widget. The task of filtering horizontal movements is up to the caller.
-
-.. _twofinger_scrolling:
-
-------------------------------------------------------------------------------
-Two-finger scrolling
-------------------------------------------------------------------------------
-
-The default on two-finger capable touchpads (almost all modern touchpads are
-capable of detecting two fingers). Scrolling is triggered by two fingers
-being placed on the surface of the touchpad, then moving those fingers
-vertically or horizontally.
-
-.. figure:: twofinger-scrolling.svg
-    :align: center
-
-    Vertical and horizontal two-finger scrolling
-
-For scrolling to trigger, a built-in distance threshold has to be met, but once
-engaged, any movement will scroll. In other words: to start scrolling, a
-sufficiently large movement is required; once scrolling, tiny amounts of
-movements will translate into tiny scroll movements.
-Scrolling in both directions at once is possible by meeting the required
-distance thresholds to enable each direction separately.
-
-When a scroll gesture remains close to perfectly straight, it will be held to
-exact 90-degree angles; but if the gesture moves diagonally, it is free to
-scroll in any direction.
-
-Two-finger scrolling requires the touchpad to track both touch points with
-reasonable precision. Unfortunately, some so-called "semi-mt" touchpads can
-only track the bounding box of the two fingers rather than the actual
-position of each finger. In addition, that bounding box usually suffers from
-a low resolution, causing jumpy movement during two-finger scrolling.
-libinput does not provide two-finger scrolling on those touchpads.
-
-.. _edge_scrolling:
-
-------------------------------------------------------------------------------
-Edge scrolling
-------------------------------------------------------------------------------
-
-On some touchpads, edge scrolling is available, triggered by moving a single
-finger along the right edge (vertical scroll) or bottom edge (horizontal
-scroll).
-
-.. figure:: edge-scrolling.svg
-    :align: center
-
-    Vertical and horizontal edge scrolling
-
-Due to the layout of the edges, diagonal scrolling is not possible. The
-behavior of edge scrolling using both edges at the same time is undefined.
-
-Edge scrolling overlaps with :ref:`clickpad_softbuttons`. A physical click on
-a clickpad ends scrolling.
-
-.. _button_scrolling:
-
-------------------------------------------------------------------------------
-On-Button scrolling
-------------------------------------------------------------------------------
-
-On-button scrolling converts the motion of a device into scroll events while
-a designated button is held down. For example, Lenovo devices provide a
-`pointing stick <http://en.wikipedia.org/wiki/Pointing_stick>`_ that emulates
-scroll events when the trackstick's middle mouse button is held down.
-
-.. note:: On-button scrolling is enabled by default for pointing sticks. This
-	prevents middle-button dragging; all motion events while the middle
-	button is down are converted to scroll events.
-
-.. figure:: button-scrolling.svg
-    :align: center
-
-    Button scrolling
-
-The button may be changed with
-**libinput_device_config_scroll_set_button()** but must be on the same device as
-the motion events. Cross-device scrolling is not supported but
-for one exception: libinput's :ref:`t440_support` enables the use of the middle
-button for button scrolling (even when the touchpad is disabled).
-
-If the scroll button lock is enabled (see
-**libinput_device_config_scroll_set_button_lock()**), the button does not
-need to be held down. Pressing and releasing the button once enables the
-button lock, the button is now considered logically held down. Pressing and
-releasing the button a second time logically releases the button. While the
-button is logically held down, motion events are converted to scroll events.
-
-If the button is held and used to scroll for longer than a short grace
-period, releasing the button does not engage the lock. This allows
-hold-to-scroll for short, precise adjustments without accidentally toggling
-the lock. A quick click or a brief scroll within the grace period still
-engages the lock as normal.
-
-.. _scroll_sources:
-
-------------------------------------------------------------------------------
-Scroll sources
-------------------------------------------------------------------------------
-
-.. note:: Scroll sources are deprecated with libinput 1.19. The scroll
-   source is now encoded in the event type.
-
-libinput provides a pointer axis *source* for each scroll event. The
-source can be obtained with the **libinput_event_pointer_get_axis_source()**
-function and is one of **wheel**, **finger**, or **continuous**. The source
-information lets a caller decide when to implement kinetic scrolling.
-Usually, a caller will process events of source wheel as they come in.
-For events of source finger a caller should calculate the velocity of the
-scroll motion and upon finger release start a kinetic scrolling motion (i.e.
-continue executing a scroll according to some friction factor).
-libinput expects the caller to be in charge of widget handling, the source
-information is thus enough to provide kinetic scrolling on a per-widget
-basis. A caller should cancel kinetic scrolling when the pointer leaves the
-current widget or when a key is pressed.
-
-See the **libinput_event_pointer_get_axis_source()** for details on the
-behavior of each scroll source.
-
-See also http://who-t.blogspot.com.au/2015/03/libinput-scroll-sources.html
-
-.. _natural_scrolling:
-
-------------------------------------------------------------------------------
-Natural scrolling vs. traditional scrolling
-------------------------------------------------------------------------------
-
-Natural scrolling is the term (probably) coined by Apple for matching
-the motion of the scroll device with the direction of the **content**.
-
-In traditional scrolling, moving the wheel down causes the scroll bar
-indicators to move down and the content to move up. In natural scrolling,
-moving the wheel down causes the content to move down and the scroll bar
-indicators to move up. This method of scrolling matches the interaction
-with content on touch screens where a movement down also moves the content
-down.
-
-libinput supports natural scrolling for all its scroll methods; it can
-be enabled with the
-**libinput_device_config_scroll_set_natural_scroll_enabled()** function.

-.. _seats:
-
-==============================================================================
-Seats
-==============================================================================
-
-Each device in libinput is assigned to one seat.
-A seat has two identifiers, the physical name and the logical name. The
-physical name is summarized as the list of devices a process on the same
-physical seat has access to. The logical seat name is the seat name for a
-logical group of devices. A compositor may use that to create additional
-seats as independent device sets. Alternatively, a compositor may limit
-itself to a single logical seat, leaving a second compositor to manage
-devices on the other logical seats.
-
-.. _seats_overview:
-
-------------------------------------------------------------------------------
-Overview
-------------------------------------------------------------------------------
-
-Below is an illustration of how physical seats and logical seats interact:
-
-.. graphviz:: seats-sketch.gv
-
-The devices "Foo", "Bar" and "Spam" share the same physical seat and are
-thus available in the same libinput context. Only "Foo" and "Bar" share the
-same logical seat. The device "Egg" is not available in the libinput context
-associated with the physical seat 0.
-
-The above graph is for illustration purposes only. In libinput, a struct
-**libinput_seat** comprises both physical seat and logical seat. From a
-caller's point-of-view the above device layout is presented as:
-
-.. graphviz:: seats-sketch-libinput.gv
-
-Thus, devices "Foo" and "Bar" both reference the same struct
-**libinput_seat**, all other devices reference their own respective seats.
-
-.. _seats_and_features:
-
-------------------------------------------------------------------------------
-The effect of seat assignment
-------------------------------------------------------------------------------
-
-A logical set is interpreted as a group of devices that usually belong to a
-single user that interacts with a computer. Thus, the devices are
-semantically related. This means for devices within the same logical seat:
-
-- if the same button is pressed on different devices, the button should only
-  be considered logically pressed once.
-- if the same button is released on one device, the button should be
-  considered logically down if still down on another device.
-- if two different buttons or keys are pressed on different devices, the
-  logical state is that of both buttons/keys down.
-- if a button is pressed on one device and another device moves, this should
-  count as dragging.
-- if two touches are down on different devices, the logical state is that of
-  two touches down.
-
-libinput provides functions to aid with the above:
-**libinput_event_pointer_get_seat_button_count()**,
-**libinput_event_keyboard_get_seat_key_count()**, and
-**libinput_event_touch_get_seat_slot()**.
-
-Internally, libinput counts devices within the same logical seat as related.
-Cross-device features only activate if all required devices are in the same
-logical seat. For example, libinput will only activate the top software
-buttons (see :ref:`t440_support`) if both trackstick and touchpad are assigned
-to the same logical seat.
-
-
-.. _changing_seats:
-
-------------------------------------------------------------------------------
-Changing seats
-------------------------------------------------------------------------------
-
-A device may change the logical seat it is assigned to at runtime with
-**libinput_device_set_seat_logical_name()**. The physical seat is immutable and
-may not be changed.
-
-Changing the logical seat for a device is equivalent to unplugging the
-device and plugging it back in with the new logical seat. No device state
-carries over across a logical seat change.
