# To change the gitlab CI, edit .gitlab-ci/ci.template and/or .gitlab-ci/config.yaml
|
|
||||||
# and run ci-fairy generate-template. For details, see

# https://freedesktop.pages.freedesktop.org/ci-templates/ci-fairy.html#templating-gitlab-ci-yml
|
|

|
|
||||||
# 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'
|
|
||||||

|
|
||||||
# to work.
|
|

#
|

%description
|
|
||||||
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.

Hi. This is a friendly reminder that the maintainers are waiting on some information by
|
|
||||||
you (or maybe someone cc'd on this bug). If the information is not provided we may not
|
|

be able to proceed with this issue or merge request. Please check the recent comments, thanks.

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.

Looks like we may need some extra information. Please **attach** (do not paste) the full output

of `libinput record` and `libinput debug-events --verbose` (if you haven't yet).
|

The [documentation](https://wayland.freedesktop.org/libinput/doc/latest/tools.html#libinput-record-and-libinput-replay)
|

has some information on what we're looking for to be able to triage bugs.

Looks like we may need some extra information that isn't yet available in this issue.
|
|
||||||
Please **attach** (do not paste) the output of [`hid-recorder`](https://github.com/hidutils/hid-recorder/)
|
|
||||||
for this device (run `sudo hid-recorder` without argument and it will let you pick the device).
|
|
||||||
This should show the data the kernel receives from the device and may provide a hint on what's going on here.

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,
|
|
||||||
making it possible to change the properties of a device and/or the events to make them compatible with the
|
|
||||||
expectations the kernel and userspace has of such devices.
|
|
||||||
|
|
||||||
Please see the [udev-hid-bpf documentation](https://libevdev.pages.freedesktop.org/udev-hid-bpf/) for details
|
|
||||||
and/or in particular the [udev-hid-bpf tutorial](https://libevdev.pages.freedesktop.org/udev-hid-bpf/tutorial.html)
|
|
||||||
if you need to enable a new device.

This bug looks like a kernel issue and it cannot be fixed
|
|
||||||
in libinput directly. I'm closing this bug but do feel free
|
|
||||||
to continue discussing the issue here.
|

|

Kernel bugs are usually best sent to the [`linux-input` list](https://lore.kernel.org/linux-input/).

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. Looks like the pipeline failed because one or more of the commits in this MR do not meet our requirements.
|
|
||||||
Most commonly this the format of the commit message itself. The "Test summary" above has the details.
|
|
||||||
|
|
||||||
Please see [our docs for commit messages](https://wayland.freedesktop.org/libinput/doc/latest/contributing.html#commit-messages)

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)

|
|
||||||
|
|
||||||
- avoid uninitialized variables where possible, declare them late instead.
|
|
||||||
Note that most of libinput predates this style, try to stick with the code
|
|
||||||
around you if in doubt.
|
|
||||||
|
|
||||||
wrong:
|
|
||||||
|
|
||||||
```c
|
|
||||||
int *a;
|
|
||||||
int b = 7;
|
|
||||||
|
|
||||||
... some code ...
|
|
||||||
|
|
||||||
a = zalloc(32);
|
|
||||||
```
|
|
||||||
|
|
||||||
right:
|
|
||||||
|
|
||||||
```c
|
|
||||||
int b = 7;
|
|
||||||
... some code ...
|
|
||||||
|
|
||||||
int *a = zalloc(32);
|
|
||||||
```
|
|
||||||
|
|
||||||
- avoid calling non-obvious functions inside declaration blocks for multiple
|
|
||||||
variables.
|
|
||||||
|
|
||||||
bad:
|
|
||||||
|
|
||||||
```c
|
|
||||||
{
|
|
||||||
int a = 7;
|
|
||||||
int b = some_complicated_function();
|
|
||||||
int *c = zalloc(32);
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
better:
|
|
||||||
```c
|
|
||||||
{
|
|
||||||
int a = 7;
|
|
||||||
int *c = zalloc(32);
|
|
||||||
|
|
||||||
int b = some_complicated_function();
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
There is a bit of gut-feeling involved with this, but the goal is to make
|
|
||||||
the variable values immediately recognizable.
|
|
||||||
|
|
||||||
- Where statements are near-identical and repeated, try to keep them
|
|
||||||
identical:
|
|
||||||
|
|
||||||
bad:
|
|
||||||
```c
|
|
||||||
int a = get_some_value(x++);
|
|
||||||
do_something(a);
|
|
||||||
a = get_some_value(x++);
|
|
||||||
do_something(a);
|
|
||||||
a = get_some_value(x++);
|
|
||||||
do_something(a);
|
|
||||||
```
|
|
||||||
better:
|
|
||||||
|
|
||||||
```c
|
|
||||||
int a;
|
|
||||||
a = = get_some_value(x++);
|
|
||||||
do_something(a);
|
|
||||||
a = get_some_value(x++);
|
|
||||||
do_something(a);
|
|
||||||
a = get_some_value(x++);
|
|
||||||
do_something(a);
|
|
||||||
```
|
|
||||||
|
|
||||||
- if/else: { on the same line, no curly braces if both blocks are a single
|
|
||||||
statement. If either if or else block are multiple statements, both must
|
|
||||||
have curly braces.
|
|
||||||
|
|
||||||
```c
|
|
||||||
if (foo) {
|
|
||||||
blah();
|
|
||||||
bar();
|
|
||||||
} else {
|
|
||||||
a = 10;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
- public functions MUST be doxygen-commented, use doxygen's `@foo` rather than
|
|
||||||
`\foo` notation
|
|
||||||
|
|
||||||
- `#include "config.h"` comes first, followed by system headers, followed by
|
|
||||||
external library headers, followed by internal headers.
|
|
||||||
sort alphabetically where it makes sense (specifically system headers)
|
|
||||||
|
|
||||||
```c
|
|
||||||
#include "config.h"
|
|
||||||
|
|
||||||
#include <stdio.h>
|
|
||||||
#include <string.h>
|
|
||||||
|
|
||||||
#include <libevdev/libevdev.h>
|
|
||||||
|
|
||||||
#include "libinput-private.h"
|
|
||||||
```
|
|
||||||
|
|
||||||
- goto jumps only to the end of the function, and only for good reasons
|
|
||||||
(usually cleanup). goto never jumps backwards
|
|
||||||
|
|
||||||
- Use stdbool.h's bool for booleans within the library (instead of `int`).
|
|
||||||
Exception: the public API uses int, not bool.
|
|
||||||

# 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 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 needs 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
|
||||||
|
========
|
||||||
|
|
||||||
|
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](http://cgit.freedesktop.org/wayland/weston/), the Wayland reference
|
||||||
|
compositor.
|
||||||
|
|
||||||
|
Architecture
|
||||||
|
------------
|
||||||
|
|
||||||
|
libinput is not used directly by applications, rather it is used by the
|
||||||
|
xf86-input-libinput X.Org driver or wayland compositors. The typical
|
||||||
|
software stack for a system running Wayland is:
|
||||||
|
|
||||||
|
@dotfile libinput-stack-wayland.gv
|
||||||
|
|
||||||
|
Where the Wayland compositor may be Weston, mutter, KWin, etc. Note that
|
||||||
|
Wayland encourages the use of toolkits, so the Wayland client (your
|
||||||
|
application) does not usually talk directly to the compositor but rather
|
||||||
|
employs a toolkit (e.g. GTK) to do so.
|
||||||
|
|
||||||
|
The simplified software stack for a system running X.Org is:
|
||||||
|
|
||||||
|
@dotfile libinput-stack-xorg.gv
|
||||||
|
|
||||||
|
Again, on a modern system the application does not usually talk directly to
|
||||||
|
the X server using Xlib but rather employs a toolkit to do so.
|
||||||

||||||

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.

||||||

|
Clickpad is the name given to touchpads without physical buttons below the
|
||||||
|
touchpad. Instead, the whole touchpad acts as a button and left or right
|
||||||
|
button clicks are distinguished by the location and/or number of fingers on
|
||||||
|
the touchpad. <a href="http://www.synaptics.com/en/clickpad.php">"ClickPad" is
|
||||||
|
a trademark by Synaptics Inc.</a> but for simplicity we refer to any
|
||||||
|
touchpad with the above feature as Clickpad, regardless of the manufacturer.
|
||||||
|
|
||||||
|
A clickpad is always marked with the <a
|
||||||
|
href="https://www.kernel.org/doc/Documentation/input/event-codes.txt">INPUT_PROP_BUTTONPAD</a> property.
|
||||||
|
To perform a right-click on a Clickpad, libinput provides @ref
|
||||||
|
software_buttons and @ref clickfinger.
|
||||||
|
|
||||||
|
In the page below, the term "click" shall refer to a physical button press
|
||||||
|
and/or release of the touchpad, the term "button event" refers to the events
|
||||||
|
generated by libinput and passed to the caller in response to a click.
|
||||||
|
|
||||||
|
@section software_buttons Software button areas
|
||||||
|
|
||||||
|
On most clickpads, this is the default behavior. 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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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 though as
|
||||||
|
many touchpads do not have visible markings for the middle button the exact
|
||||||
|
location of the button is not visibly obvious.
|
||||||
|
|
||||||
|
@image html software-buttons.svg "Left, right and middle-button click with software button areas"
|
||||||
|
|
||||||
|
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
|
||||||
|
|
||||||
|
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
|
||||||
|
- a finger in the software button area does not move the pointer
|
||||||
|
- if a finger moves out out of the button area it will control the pointer
|
||||||
|
if it's the first finger in the main area
|
||||||
|
- once a finger has moved out of the button area, it cannot move back in and
|
||||||
|
trigger a right or middle button event
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
@section 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. The location of the fingers does not matter and there are no
|
||||||
|
software-defined button areas.
|
||||||
|
|
||||||
|
@image html clickfinger.svg "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.
|
||||||
|
|
||||||
|
@image html clickfinger-distance.svg "Illustration of the distance detection algorithm"
|
||||||
|
|
||||||
|
In the illustration above the red area marks the proximity area around the
|
||||||
|
first finger. Since the thumb is outside of that area libinput considers the
|
||||||
|
click a single-finger click rather than a two-finger click.
|
||||||
|
|
||||||
|
Clickfinger configuration can be enabled through the
|
||||||
|
libinput_device_config_click_set_method() call. If clickfingers are
|
||||||
|
enabled on a touchpad with top software buttons, the top area will keep
|
||||||
|
acting as softbuttons for use with the trackpoint. Clickfingers will be used
|
||||||
|
everywhere else on the touchpad.
|
||||||
|
|
||||||
|
@section special_clickpads 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 t440_support "Lenovo *40 series touchpad 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
|
||||||
|
treated like traditional touchpads.

libinput supports some static configuration through udev properties.
|

|
These properties are read when the device is initially added
|
||||||

|
The udev property is parsed as 6 floating point numbers separated by a

libinput requires the <b>ID_INPUT</b> property to be set on a device,
|
||||||
|
otherwise the device will be ignored. In addition, one of <b>
|
||||||
|
ID_INPUT_KEYBOARD, ID_INPUT_KEY, ID_INPUT_MOUSE, ID_INPUT_TOUCHPAD,
|
||||||
|
ID_INPUT_TOUCHSCREEN, ID_INPUT_TABLET, ID_INPUT_JOYSTICK,
|

|
||||||
|
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 <b>ID_INPUT_TOUCHPAD</b> setting
|
||||||
|
and change it into an <b>ID_INPUT_TABLET</b> setting. This rule would apply
|
||||||
|
for a device with the vendor/model ID of 012a/034b.

|
The property <b>LIBINPUT_MODEL_LENOVO_X220_TOUCHPAD_FW81</b> 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
|
||||||
|
continuos 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.

Frequently asked questions about libinput.
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
In a GNOME X.Org stack a user would usually toggle an option in
|
||||||
|
the gnome-control-center which adjusts a gsettings entry. That change is
|
||||||
|
picked up by gnome-settings-daemon and applied to the device by adjusting
|
||||||
|
input device properties that the xf86-input-libinput driver provides.
|
||||||
|
The input device property changes map to the respective libinput
|
||||||
|
configuration options.
|
||||||
|
|
||||||
|
@dotfile 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.

@page gestures Gestures
|
||||||
|
|
||||||
|
libinput supports basic gestures on touchpads and other indirect input
|
||||||
|
devices. Two types of gestures are supported: @ref gestures_pinch and @ref
|
||||||
|
gestures_swipe. Support for gestures depends on the hardware device, most
|
||||||
|
touchpads support both gestures and any device that may send gesture events
|
||||||
|
has the @ref LIBINPUT_DEVICE_CAP_GESTURE capability set.
|
||||||
|
|
||||||
|
Note that libinput **does not** support gestures on touchscreens, see
|
||||||
|
@ref gestures_touchscreens.
|
||||||
|
|
||||||
|
@section gestures_lifetime Lifetime of a gesture
|
||||||
|
|
||||||
|
A gesture's lifetime has three distinct stages: begin, update and end, each
|
||||||
|
with their own event types. Begin is sent when the fingers are first set
|
||||||
|
down or libinput decides that the gesture begins. For @ref gestures_pinch
|
||||||
|
this sets the initial scale. Any events changing properties of the gesture
|
||||||
|
are sent as update events. On termination of the gesture, an end event is
|
||||||
|
sent.
|
||||||
|
|
||||||
|
A gesture includes the finger count (see
|
||||||
|
libinput_event_gesture_get_finger_count()) and that finger count remains the
|
||||||
|
same for the lifetime of a gesture. Thus, if a user puts down a fourth
|
||||||
|
finger during a three-finger swipe gesture, libinput will end
|
||||||
|
the three-finger gesture and, if applicable, start a four-finger swipe
|
||||||
|
gesture. A caller may decide that those gestures are semantically identical
|

@section 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.
|
||||||
|
|
||||||
|
@image html pinch-gestures.svg "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.
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
@image html swipe-gestures.svg "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.
|
||||||
|
|
||||||
|
@section 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:
|
||||||
|
|
||||||
|
@image html touchscreen-gestures.svg "Context-sensitivity of touchscreen gestures"
|
||||||
|
|
||||||
|
In this 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 only has knowledge of the finger
|
||||||
|
coordinates (and even then only in device coordinates, not in screen
|
||||||
|
coordinates) and thus cannot differentiate the two.
|
||||||
|
|
||||||
|
@section gestures_softbuttons Gestures with enabled software buttons
|
||||||
|
|
||||||
|
If the touchpad device is a @ref touchpads_buttons_clickpads "Clickpad", it
|
||||||
|
is recommended that a caller switches to @ref clickfinger.
|
||||||
|
Usually fingers placed in a @ref software_buttons "software button area" is not
|
||||||
|
considered for gestures, resulting in some gestures to be interpreted as
|
||||||
|
pointer motion or two-finger scroll events.
|
||||||
|
|
||||||
|
@image html pinch-gestures-softbuttons.svg "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.
|
||||||
|
|
||||||
|
@section 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, it's location cannot be
|
||||||
|
determined.
|
||||||
|
|
||||||
|
@image html gesture-2fg-ambiguity.svg "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.

@page palm_detection Palm detection
|

|
|

|
Palm detection tries to identify accidental touches while typing.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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 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.
|
||||||
|
|
||||||
|
@section palm_exclusion_zones Palm exclusion zones
|
||||||
|
|
||||||
|
libinput enables palm detection on the edge 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.
|
||||||
|
|
||||||
|
Each exclusion zone is divided into a top part and a bottom part. A touch
|
||||||
|
starting in the top part of 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 top part of the exclusion zone. Despite being a
|
||||||
|
tapping motion, it does not generate an emulated button event. Touch 'D'
|
||||||
|
likewise occurs within the exclusion zone but in the bottom half. libinput
|
||||||
|
will generate a button event for this touch.
|
||||||
|
|
||||||
|
@image html palm-detection.svg
|

|
|
||||||
|
@section trackpoint-disabling Palm detection during trackpoint use
|
||||||
|
|
||||||
|
If a device provides a <a
|
||||||
|
href="http://en.wikipedia.org/wiki/Pointing_stick">trackpoint</a>, 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 t440_support "top software buttons"
|
||||||
|
remain enabled.
|
||||||
|
|
||||||
|
@section 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 t440_support "software-emulated buttons".
|
||||||
|
|
||||||
|
Disable-while-typing can be enabled and disabled by calling
|
||||||
|
libinput_device_config_dwt_set_enabled().
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|

@page 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.
|
||||||
|
|
||||||
|
@section ptraccel-profiles Pointer acceleration profiles
|
||||||
|
|
||||||
|
The profile decides the general method of pointer acceleration.
|
||||||
|
libinput currently supports two profiles: "adaptive" and "flat". The aptive
|
||||||
|
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). Most of this document
|
||||||
|
describes the adaptive pointer acceleration.
|
||||||
|
|
||||||
|
@section ptraccel-velocity Velocity calculation
|
||||||
|
|
||||||
|
The device's speed of movement is measured across multiple input events
|
||||||
|
through so-called "trackers". Each event prepends a the 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
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
@image html ptraccel-linear.svg "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.
|
||||||
|
|
||||||
|
@section 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).
|
||||||
|
|
||||||
|
@image html ptraccel-low-dpi.svg "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.
|
||||||
|
|
||||||
|
@section ptraccel-touchpad Pointer acceleration on touchpads
|
||||||
|
|
||||||
|
Touchpad pointer acceleration uses 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.
|
||||||
|
|
||||||
|
@image html ptraccel-touchpad.svg "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.
|
||||||
|
|
||||||
|
@section ptraccel-trackpoint Pointer acceleration on trackpoints
|
||||||
|
|
||||||
|
Trackpoint pointer acceleration uses the @ref ptraccel-low-dpi profile, with a
|
||||||
|
constant deceleration factor taking the place of the DPI settings.
|
||||||
|
|
||||||
|
@image html ptraccel-trackpoint.svg "Pointer acceleration curves for trackpoints"
|
||||||
|
|
||||||
|
The image above shows the trackpoint acceleration profile in comparison to the
|
||||||
|
@ref ptraccel-linear. The constant acceleration factor, usually applied by
|
||||||
|
udev, shapes the acceleration profile.
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
@section ptraccel-tablet Pointer acceleration on tablets
|
||||||
|
|
||||||
|
Pointer acceleration for relative motion on tablet devices is a flat
|
||||||
|
acceleration, with the speed seeting slowing down or speeding up the pointer
|
||||||
|
motion by a constant factor. Tablets do not allow for switchable profiles.

quicker bugfix.
|
||||||
|
|

|
specific a bug description is, the easier it is to fix. The @ref
|
||||||
|
libinput-debug-events helper tool can help identify whether the bug is in
|
||||||
|
libinput at all. This tool is a direct hook to libinput without a desktop
|
||||||
|
stack in between and can thus help to identify whether a bug is in libinput
|
||||||
|
or in one of the higher layers. See the @ref libinput-debug-events section

|
for information on this tool.
|
||||||
|
|
||||||
|
@section triage Required information for triage
|
||||||
|
|
||||||
|
When you file a bug, please attach the following information:
|
||||||
|
- a virtual description of your input device, see @ref evemu. This is the
|
||||||
|
most important piece of information, do not forget it!
|
||||||
|
- the libinput version. Either the package version from your distribution
|
||||||
|
or, when running from git: <tt>git log -n 1 HEAD</tt> or <tt>git describe
|
||||||
|
HEAD</tt>. As a last resort: <tt>libinput-list-devices --version</tt>.
|
||||||
|
- the current libinput settings for the device. This is a bit harder to
|
||||||
|
obtain, for now we'll assume you are running X11. The current settings can
|
||||||
|
be obtained with <tt>xinput list-props "your device name"</tt>. Use
|
||||||
|
<tt>xinput list</tt> to obtain the device name.
|
||||||
|
- if the device is a touchpad or a pointing stick, the vendor model number
|
||||||
|
of your laptop, and the content of <tt>/sys/class/dmi/id/modalias</tt>.
|

|
touching the screen/touchpad.
|
||||||
|
|
||||||
|
@note The longer the recording, the harder it is to identify the event

sequence triggering the bug. Please keep the event sequence as short as possible.
|

|
|
||||||
|
To verify that the recording contains the bug, you can replay it on your
|
||||||
|
device. For example, to replay the sequence recorded in the example above:
|
||||||
|
@code
|
||||||
|
$ sudo evemu-play /dev/input/event4 < scroll.evemu
|
||||||
|
@endcode
|
||||||
|
|
||||||
|
If the bug is triggered by replaying on your device, attach the recording to
|
||||||
|
the bug report.
|
||||||
|
|
||||||
|
@note libinput does not affect the evemu recording. libinput and evemu talk
|
||||||
|
directly to the kernel's device nodes. An evemu recording is not influenced

@page 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 clickpad_softbuttons
|
||||||
|
"clickpads") 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.
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
@section 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.
|
||||||
|
|
||||||
|
@image html twofinger-scrolling.svg "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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
@section 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).
|
||||||
|
|
||||||
|
@image html edge-scrolling.svg "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.
|
||||||
|
|
||||||
|
@section 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
|
||||||
|
<a href="http://en.wikipedia.org/wiki/Pointing_stick">pointing stick</a> 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.
|
||||||
|
|
||||||
|
@image html button-scrolling.svg "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).
|
||||||
|
|
||||||
|
@section scroll_sources Scroll sources
|
||||||
|
|
||||||
|
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.

This page provides details about the graphics tablet
|
||||||
|
support in libinput. Note that the term "tablet" in libinput refers to
|
||||||
|
graphics tablets only (e.g. Wacom Intuos), not to tablet devices like the
|
||||||
|
Apple iPad.

@section tablet-tools Pad buttons vs. tablet tools
|
||||||
|
|
||||||
|
Most tablets provide two types of devices. The physical tablet often
|
||||||
|
provides a number of buttons and a touch ring or strip. Interaction on the
|
||||||
|
drawing surface of the tablet requires a tool, usually in the shape of a
|
||||||
|
stylus. The libinput interface exposed by devices with the @ref
|
||||||
|
LIBINPUT_DEVICE_CAP_TABLET_TOOL capability applies only to events generated
|
||||||
|
by tools.
|
||||||
|
|
||||||
|
Buttons, rings or strips on the physical tablet hardware (the "pad") are
|
||||||
|
exposed by devices with the @ref LIBINPUT_DEVICE_CAP_TABLET_PAD capability.
|
||||||
|
Pad events do not require a tool to be in proximity. Note that both
|
||||||
|
capabilities may exist on the same device though usually they are split
|
||||||
|
across multiple kernel devices.
|
||||||
|
|
||||||
|
@image html tablet-interfaces.svg "Difference between Pad and Tool buttons"
|
||||||
|
|
||||||
|
Touch events on the tablet integrated into a screen itself are exposed
|
||||||
|
through the @ref LIBINPUT_DEVICE_CAP_TOUCH capability. Touch events on a
|
||||||
|
standalone tablet are exposed through the @ref LIBINPUT_DEVICE_CAP_POINTER
|
||||||
|
capability. In both cases, the kernel usually provides a separate event
|
||||||
|
node for the touch device, resulting in a separate libinput device.
|
||||||
|
See libinput_device_get_device_group() for information on how to associate
|
||||||
|
the touch part with other devices exposed by the same physical hardware.
|
||||||
|
|
||||||
|
@section tablet-tip Tool tip events vs. tool button events
|
||||||
|
|
||||||
|
The primary use of a tablet tool is to draw on the surface of the tablet.
|
||||||
|
When the tool tip comes into contact with the surface, libinput sends an
|
||||||
|
event of type @ref LIBINPUT_EVENT_TABLET_TOOL_TIP, and again when the tip
|
||||||
|
ceases contact with the surface.
|
||||||
|
|
||||||
|
Tablet tools may send button events; these are exclusively for extra buttons
|
||||||
|
unrelated to the tip. A button event is independent of the tip and can while
|
||||||
|
the tip is down or up.
|
||||||
|
|
||||||
|
Some tablet tools' pressure detection is too sensitive, causing phantom
|
||||||
|
touches when the user only slightly brushes the surfaces. For example, some
|
||||||
|
tools are capable of detecting 1 gram of pressure.
|
||||||
|
|
||||||
|
libinput uses a device-specific pressure threshold to determine when the tip
|
||||||
|
is considered logically down. As a result, libinput may send a nonzero
|
||||||
|
pressure value while the tip is logically up. Most application can and
|
||||||
|
should ignore pressure information until they receive the event of type @ref
|
||||||
|
LIBINPUT_EVENT_TABLET_TOOL_TIP. Applications that require extremely
|
||||||
|
fine-grained pressure sensitivity should use the pressure data instead of
|
||||||
|
the tip events to determine a logical tip down state and treat the tip
|
||||||
|
events like axis events otherwise.
|
||||||
|
|
||||||
|
Note that the pressure threshold to trigger a logical tip event may be zero
|
||||||
|
on some devices. On tools without pressure sensitivity, determining when a
|
||||||
|
tip is down is device-specific.
|
||||||
|
|
||||||
|
@section tablet-relative-motion Relative motion for tablet tools
|
||||||
|
|
||||||
|
libinput calculates the relative motion vector for each event and converts
|
||||||
|
it to the same coordinate space that a normal mouse device would use. For
|
||||||
|
the caller, this means that the delta coordinates returned by
|
||||||
|
libinput_event_tablet_tool_get_dx() and
|
||||||
|
libinput_event_tablet_tool_get_dy() can be used identical to the delta
|
||||||
|
coordinates from any other pointer event. Any resolution differences between
|
||||||
|
the x and y axes are accommodated for, a delta of N/N represents a 45 degree
|
||||||
|
diagonal move on the tablet.
|
||||||
|
|
||||||
|
The delta coordinates are available for all tablet events, it is up to the
|
||||||
|
caller to decide when a tool should be used in relative mode. It is
|
||||||
|
recommended that mouse and lens cursor tool default to relative mode and
|
||||||
|
all pen-like tools to absolute mode.
|
||||||
|
|
||||||
|
If a tool in relative mode must not use pointer acceleration, callers
|
||||||
|
should use the absolute coordinates returned by
|
||||||
|
libinput_event_tablet_tool_get_x() and libinput_event_tablet_tool_get_y()
|
||||||
|
and calculate the delta themselves. Callers that require exact physical
|
||||||
|
distance should also use these functions to calculate delta movements.
|
||||||
|
|
||||||
|
@section tablet-axes Special axes on tablet tools
|
||||||
|
|
||||||
|
A tablet tool usually provides additional information beyond x/y positional
|
||||||
|
information and the tip state. A tool may provide the distance to the tablet
|
||||||
|
surface and the pressure exerted on the tip when in contact. Some tablets
|
||||||
|
additionally provide tilt information along the x and y axis.
|
||||||
|
|
||||||
|
@image html tablet-axes.svg "Illustration of the distance, pressure and tilt axes"
|
||||||
|
|
||||||
|
The granularity and precision of the distance and pressure axes varies
|
||||||
|
between tablet devices and cannot usually be mapped into a physical unit.
|
||||||
|
libinput normalizes distance and pressure into the [0, 1] range.
|
||||||
|
|
||||||
|
While the normalization range is identical for these axes, a caller should
|
||||||
|
not interpret identical values as identical across axes, i.e. a value v1 on
|
||||||
|
the distance axis has no relation to the same value v1 on the pressure axis.
|
||||||
|
|
||||||
|
The tilt axes provide the angle in degrees between a vertical line out of
|
||||||
|
the tablet and the top of the stylus. The angle is measured along the x and
|
||||||
|
y axis, respectively, a positive tilt angle thus means that the stylus' top
|
||||||
|
is tilted towards the logical right and/or bottom of the tablet.
|
||||||
|
|
||||||
|
@section tablet-fake-proximity Handling of proximity events
|
||||||
|
|
||||||
|
libinput's @ref LIBINPUT_EVENT_TABLET_TOOL_PROXIMITY events notify a caller
|
||||||
|
when a tool comes into sensor range or leaves the sensor range. On some
|
||||||
|
tools this range does not represent the physical range but a reduced
|
||||||
|
tool-specific logical range. If the range is reduced, this is done
|
||||||
|
transparent to the caller.
|
||||||
|
|
||||||
|
For example, the Wacom mouse and lens cursor tools are usually
|
||||||
|
used in relative mode, lying flat on the tablet. Movement typically follows
|
||||||
|
the interaction normal mouse movements have, i.e. slightly lift the tool and
|
||||||
|
place it in a separate location. The proximity detection on Wacom
|
||||||
|
tablets however extends further than the user may lift the mouse, i.e. the
|
||||||
|
tool may not be lifted out of physical proximity. For such tools, libinput
|
||||||
|
provides software-emulated proximity.
|
||||||
|
|
||||||
|
Events from the pad do not require proximity, they may be sent any time.
|
||||||
|
|
||||||
|
@section tablet-pressure-offset Pressure offset on worn-out tools
|
||||||
|
|
||||||
|
When a tool is used for an extended period it can wear down physically. A
|
||||||
|
worn-down tool may never return a zero pressure value. Even when hovering
|
||||||
|
above the surface, the pressure value returned by the tool is nonzero,
|
||||||
|
creating a fake surface touch and making interaction with the tablet less
|
||||||
|
predictable.
|
||||||
|
|
||||||
|
libinput automatically detects pressure offsets and rescales the remaining
|
||||||
|
pressure range into the available range, making pressure-offsets transparent
|
||||||
|
to the caller. A tool with a pressure offset will thus send a 0 pressure
|
||||||
|
value for the detected offset and nonzero pressure values for values higher
|
||||||
|
than that offset.
|
||||||
|
|
||||||
|
Some limitations apply to avoid misdetection of pressure offsets,
|
||||||
|
specifically:
|
||||||
|
- pressure offset is only detected on proximity in, and if a device is
|
||||||
|
capable of detection distances,
|
||||||
|
- pressure offset is only detected if the distance between the tool and the
|
||||||
|
tablet is high enough,
|
||||||
|
- pressure offset is only used if it is 20% or less of the pressure range
|
||||||
|
available to the tool. A pressure offset higher than 20% indicates either
|
||||||
|
a misdetection or a tool that should be replaced, and
|
||||||
|
- if a pressure value less than the current pressure offset is seen, the
|
||||||
|
offset resets to that value.
|
||||||
|
|
||||||
|
Pressure offsets are not detected on @ref LIBINPUT_TABLET_TOOL_TYPE_MOUSE
|
||||||
|
and @ref LIBINPUT_TABLET_TOOL_TYPE_LENS tools.
|
||||||
|
|
||||||
|
@section tablet-serial-numbers Tracking unique tools
|
||||||
|
|
||||||
|
Some tools provide hardware information that enables libinput to uniquely
|
||||||
|
identify the physical device. For example, tools compatible with the Wacom
|
||||||
|
Intuos 4, Intuos 5, Intuos Pro and Cintiq series are uniquely identifiable
|
||||||
|
through a serial number. libinput does not specify how a tool can be
|
||||||
|
identified uniquely, a caller should use libinput_tablet_tool_is_unique() to
|
||||||
|
check if the tool is unique.
|
||||||
|
|
||||||
|
libinput creates a struct libinput_tablet_tool on the first proximity in of
|
||||||
|
this tool. By default, this struct is destroyed on proximity out and
|
||||||
|
re-initialized on the next proximity in. If a caller keeps a reference to
|
||||||
|
the tool by using libinput_tablet_tool_ref() libinput re-uses this struct
|
||||||
|
whenever that same physical tool comes into proximity on any tablet
|
||||||
|
recognized by libinput. It is possible to attach tool-specific virtual state
|
||||||
|
to the tool. For example, a graphics program such as the GIMP may assign a
|
||||||
|
specific color to each tool, allowing the artist to use the tools like
|
||||||
|
physical pens of different color. In multi-tablet setups it is also
|
||||||
|
possible to track the tool across devices.
|
||||||
|
|
||||||
|
If the tool does not have a unique identifier, libinput creates a single
|
||||||
|
struct libinput_tablet_tool per tool type on each tablet the tool is used
|
||||||
|
on.
|
||||||
|
|
||||||
|
@section tablet-tool-types Vendor-specific tablet tool types
|
||||||
|
|
||||||
|
libinput supports a number of high-level tool types that describe the
|
||||||
|
general interaction expected with the tool. For example, a user would expect
|
||||||
|
a tool of type @ref LIBINPUT_TABLET_TOOL_TYPE_PEN to interact with a
|
||||||
|
graphics application taking pressure and tilt into account. The default
|
||||||
|
virtual tool assigned should be a drawing tool, e.g. a virtual pen or brush.
|
||||||
|
A tool of type @ref LIBINPUT_TABLET_TOOL_TYPE_ERASER would normally be
|
||||||
|
mapped to an eraser-like virtual tool. See @ref libinput_tablet_tool_type
|
||||||
|
for the list of all available tools.
|
||||||
|
|
||||||
|
Vendors may provide more fine-grained information about the tool in use by
|
||||||
|
adding a hardware-specific tool ID. libinput provides this ID to the caller
|
||||||
|
with libinput_tablet_tool_get_tool_id() but makes no promises about the
|
||||||
|
content or format of the ID.
|
||||||
|
|
||||||
|
libinput currently supports Wacom-style tool IDs as provided on the Wacom
|
||||||
|
Intuos 3, 4, 5, Wacon Cintiq and Wacom Intuos Pro series. The tool ID can
|
||||||
|
be used to distinguish between e.g. a Wacom Classic Pen or a Wacom Pro Pen.
|
||||||
|
It is the caller's responsibility to interpret the tool ID.
|
||||||
|
|
||||||
|
@section tablet-bounds Out-of-bounds motion events
|
||||||
|
|
||||||
|
Some tablets integrated into a screen (e.g. Wacom Cintiq 24HD, 27QHD and
|
||||||
|
13HD series, etc.) have a sensor larger than the display area. libinput uses
|
||||||
|
the range advertised by the kernel as the valid range unless device-specific
|
||||||
|
quirks are present. Events outside this range will produce coordinates that
|
||||||
|
may be negative or larger than the tablet's width and/or height. It is up to
|
||||||
|
the caller to ignore these events.
|
||||||
|
|
||||||
|
@image html tablet-out-of-bounds.svg "Illustration of the out-of-bounds area on a tablet"
|
||||||
|
|
||||||
|
In the image above, the display area is shown in black. The red area around
|
||||||
|
the display illustrates the sensor area that generates input events. Events
|
||||||
|
within this area will have negative coordinate or coordinates larger than
|
||||||
|
the width/height of the tablet.
|
||||||
|
|
||||||
|
If events outside the logical bounds of the input area are scaled into a
|
||||||
|
custom range with libinput_event_tablet_tool_get_x_transformed() and
|
||||||
|
libinput_event_tablet_tool_get_y_transformed() the resulting value may be
|
||||||
|
less than 0 or larger than the upper range provided. It is up to the caller
|
||||||
|
to test for this and handle or ignore these events accordingly.
|
||||||
|
|
||||||
|
@section tablet-pad-buttons Tablet pad button numbers
|
||||||
|
|
||||||
|
Tablet Pad buttons are numbered sequentially, starting with button 0. Thus
|
||||||
|
button numbers returned by libinput_event_tablet_pad_get_button_number()
|
||||||
|
have no semantic meaning, a notable difference to the button codes returned
|
||||||
|
by other libinput interfaces (e.g. libinput_event_tablet_tool_get_button()).
|
||||||
|
|
||||||
|
The Linux kernel requires all input events to have semantic event codes,
|
||||||
|
but generic buttons like those on a pad cannot easily be assigned semantic
|
||||||
|
codes. The kernel supports generic codes in the form of BTN_0 through to
|
||||||
|
BTN_9 and additional unnamed space up until code 0x10f. Additional generic
|
||||||
|
buttons are available as BTN_A in the range dedicated for gamepads and
|
||||||
|
joysticks. Thus, tablet with a large number of buttons have to map across
|
||||||
|
two semantic ranges, have to use unnamed kernel button codes or risk leaking
|
||||||
|
into an unrelated range. libinput transparently maps the kernel event codes
|
||||||
|
into a sequential button range on the pad. Callers should use external
|
||||||
|
sources like libwacom to associate button numbers to their position on the
|
||||||
|
tablet.
|
||||||
|
|
||||||
|
Some buttons may have expected default behaviors. For example, on Wacom
|
||||||
|
Intuos Pro series tablets, the button inside the touch ring is expected to
|
||||||
|
switch between a mode switch. Mode switching is a feature implemented in the
|
||||||
|
caller and libinput does not provide specific handling. Callers should use
|
||||||
|
external sources like libwacom to identify which buttons have semantic
|
||||||
|
behaviors.

@page tapping Tap-to-click behaviour
|
||||||
|
|
||||||
|
"Tapping" or "tap-to-click" is the name given to the behavior where a short
|
||||||
|
finger touch down/up sequence maps into a button click. This is most
|
||||||
|
commonly used on touchpads, but may be available on other devices.
|
||||||
|
|
||||||
|
libinput implements tapping for one, two, and three fingers, where supported
|
||||||
|
by the hardware, and maps those taps into a left, right, and middle button
|
||||||
|
click, respectively. Not all devices support three fingers, libinput will
|
||||||
|
support tapping up to whatever is supported by the hardware. libinput does
|
||||||
|
not support four-finger taps or any tapping with more than four fingers,
|
||||||
|
even though some hardware can distinguish between that many fingers.
|
||||||
|
|
||||||
|
Tapping is **disabled** by default, see [this
|
||||||
|
commit](http://cgit.freedesktop.org/wayland/libinput/commit/?id=2219c12c3aa45b80f235e761e87c17fb9ec70eae)
|
||||||
|
because:
|
||||||
|
- if you don't know that tapping is a thing (or enabled by default), you get
|
||||||
|
spurious button events that make the desktop feel buggy.
|
||||||
|
- if you do know what tapping is and you want it, you usually know where to
|
||||||
|
enable it, or at least you can search for it.
|
||||||
|
|
||||||
|
Tapping can be enabled on a per-device basis. See
|
||||||
|
libinput_device_config_tap_set_enabled() for details.
|
||||||
|
|
||||||
|
@section tapndrag Tap-and-drag
|
||||||
|
|
||||||
|
libinput also supports "tap-and-drag" where a tap immediately followed by a
|
||||||
|
finger down and that finger being held down emulates a button press. Moving
|
||||||
|
the finger around can thus drag the selected item on the screen.
|
||||||
|
Tap-and-drag is optional and can be enabled or disabled with
|
||||||
|
libinput_device_config_tap_set_drag_enabled(). Most devices have
|
||||||
|
tap-and-drag enabled by default.
|
||||||
|
|
||||||
|
Also optional is a feature called "drag lock". With drag lock disabled, lifting
|
||||||
|
the finger will stop any drag process. When enabled, libinput will ignore a
|
||||||
|
finger up event during a drag process, provided the finger is set down again
|
||||||
|
within a implementation-specific timeout. Drag lock can be enabled and
|
||||||
|
disabled with libinput_device_config_tap_set_drag_lock_enabled().
|
||||||
|
Note that drag lock only applies if tap-and-drag is be enabled.
|
||||||
|
|
||||||
|
@image html tap-n-drag.svg "Tap-and-drag process"
|
||||||
|
|
||||||
|
The above diagram explains the process, a tap (a) followed by a finger held
|
||||||
|
down (b) starts the drag process and logically holds the left mouse button
|
||||||
|
down. A movement of the finger (c) will drag the selected item until the
|
||||||
|
finger is released (e). If needed and drag lock is enabled, the finger's
|
||||||
|
position can be reset by lifting and quickly setting it down again on the
|
||||||
|
touchpad (d). This will be interpreted as continuing move and is especially
|
||||||
|
useful on small touchpads or with slow pointer acceleration.
|
||||||
|
If drag lock is enabled, the release of the mouse buttons after the finger
|
||||||
|
release (e) is triggered by a timeout. To release the button immediately,
|
||||||
|
simply tap again (f).
|
||||||
|
|
||||||
|
If two fingers are supported by the hardware, a second finger can be used to
|
||||||
|
drag while the first is held in-place.
|
||||||
|
|
||||||
|
@section tap_constraints Constraints while tapping
|
||||||
|
|
||||||
|
A couple of constraints apply to the contact to be converted into a press, the most common ones are:
|
||||||
|
- the touch down and touch up must happen within an implementation-defined timeout
|
||||||
|
- if a finger moves more than an implementation-defined distance while in contact, it's not a tap
|
||||||
|
- tapping within @ref clickpad_softbuttons "clickpad software buttons" may not trigger an event
|
||||||
|
- a tap not meeting required pressure thresholds can be ignored as accidental touch
|
||||||
|
- a tap exceeding certain pressure thresholds can be ignored (see @ref
|
||||||
|
palm_detection)
|
||||||
|
- a tap on the edges of the touchpad can usually be ignored (see @ref
|
||||||
|
palm_detection)

/**
|
||||||
|
@page test-suite libinput test suite
|
||||||
|
|
||||||
|
The libinput test suite is based on
|
||||||
|
[Check](http://check.sourceforge.net/doc/check_html/) and runs automatically
|
||||||
|
during `make check`. Check itself is wrapped into a libinput-specific test
|
||||||
|
suite called *litest*. Tests are found in `$srcdir/test/`, the test binaries are
|
||||||
|
prefixed with `test-` and can be run individually.
|
||||||
|
|
||||||
|
@section test-config X.Org config to avoid interference
|
||||||
|
|
||||||
|
uinput devices created by the test suite are usually recognised by X as
|
||||||
|
input devices. All events sent through these devices will generate X events
|
||||||
|
and interfere with your desktop.
|
||||||
|
|
||||||
|
Copy the file `$srcdir/test/50-litest.conf` into your `/etc/X11/xorg.conf.d`
|
||||||
|
and restart X. This will ignore any litest devices and thus not interfere
|
||||||
|
with your desktop.
|
||||||
|
|
||||||
|
@section test-root Permissions required to run tests
|
||||||
|
|
||||||
|
Most tests require the creation of uinput devices and access to the
|
||||||
|
resulting `/dev/input/eventX` nodes. Some tests require temporary udev rules.
|
||||||
|
<b>This usually requires the tests to be run as root</b>.
|
||||||
|
|
||||||
|
@section test-filtering Selective running of tests
|
||||||
|
|
||||||
|
litest's tests are grouped by test groups and devices. A test group is e.g.
|
||||||
|
"touchpad:tap" and incorporates all tapping-related tests for touchpads.
|
||||||
|
Each test function is (usually) run with one or more specific devices.
|
||||||
|
The `--list` commandline argument shows the list of suites and tests.
|
||||||
|
@code
|
||||||
|
$ ./test/test-device --list
|
||||||
|
device:wheel:
|
||||||
|
wheel only
|
||||||
|
blackwidow
|
||||||
|
device:invalid devices:
|
||||||
|
no device
|
||||||
|
device:group:
|
||||||
|
no device
|
||||||
|
logitech trackball
|
||||||
|
MS surface cover
|
||||||
|
mouse_roccat
|
||||||
|
wheel only
|
||||||
|
blackwidow
|
||||||
|
...
|
||||||
|
@endcode
|
||||||
|
|
||||||
|
In the above example, the "device:wheel" suite is run for the "wheel only" and
|
||||||
|
the "blackwidow" device. Both devices are automatically instantiated through
|
||||||
|
uinput by litest. The "no device" entry signals that litest does not
|
||||||
|
instantiate a uinput device for a specific test (though the test itself may
|
||||||
|
instantiate one).
|
||||||
|
|
||||||
|
The `--filter-test` argument enables selective running of tests through
|
||||||
|
basic shell-style function name matching. For example:
|
||||||
|
|
||||||
|
@code
|
||||||
|
$ ./test/test-touchpad --filter-test="*1fg_tap*"
|
||||||
|
@endcode
|
||||||
|
|
||||||
|
The `--filter-device` argument enables selective running of tests through
|
||||||
|
basic shell-style device name matching. The device names matched are the
|
||||||
|
litest-specific shortnames, see the output of `--list`. For example:
|
||||||
|
|
||||||
|
@code
|
||||||
|
$ ./test/test-touchpad --filter-device="synaptics*"
|
||||||
|
@endcode
|
||||||
|
|
||||||
|
The `--filter-group` argument enables selective running of test groups
|
||||||
|
through basic shell-style test group matching. The test groups matched are
|
||||||
|
litest-specific test groups, see the output of `--list`. For example:
|
||||||
|
|
||||||
|
@code
|
||||||
|
$ ./test/test-touchpad --filter-group="touchpad:*hover*"
|
||||||
|
@endcode
|
||||||
|
|
||||||
|
The `--filter-device` and `--filter-group` arguments can be combined with
|
||||||
|
`--list` to show which groups and devices will be affected.
|
||||||
|
|
||||||
|
@section test-verbosity Controlling test output
|
||||||
|
|
||||||
|
Each test supports the `--verbose` commandline option to enable debugging
|
||||||
|
output, see libinput_log_set_priority() for details. The `LITEST_VERBOSE`
|
||||||
|
environment variable, if set, also enables verbose mode.
|
||||||
|
|
||||||
|
@code
|
||||||
|
$ ./test/test-device --verbose
|
||||||
|
$ LITEST_VERBOSE=1 make check
|
||||||
|

libinput provides a couple of tools to query state and events. Two of these
|
||||||
|
tools are usually installed, others are @ref developer_tools only.
|
||||||
|
|
||||||
|
@section user_tools User tools
|
||||||
|
|
||||||
|
libinput ships with two tools to gather information about devices:
|
||||||
|
@ref libinput-list-devices and @ref libinput-debug-events. Both tools must
|
||||||
|
be run as root to have access to the kernel's @c /dev/input/event* device
|
||||||
|
files.
|
||||||
|
|
||||||
|
@subsection libinput-list-devices
|
||||||
|
|
||||||
|
The libinput-list-devices tool shows information about devices recognized by
|
||||||
|
libinput and can help identifying why a device behaves different than
|
||||||
|
expected. For example, if a device does not show up in the output, it is not
|
||||||
|
a supported input device.
|
||||||
|
|
||||||
|
@verbatim
|
||||||
|
$ sudo libinput-list-devices
|
||||||
|

|
||||||
|

|
||||||
|
Capabilities: pointer
|
||||||
|
Tap-to-click: disabled
|
||||||
|

|
||||||
|

|
Click methods: *button-areas clickfinger
|
||||||
|
[...]
|
||||||
|
@endverbatim
|
||||||
|
|
||||||
|
The above listing shows example output for a touchpad. The
|
||||||
|
libinput-list-devices tool lists general information about the device (the
|
||||||
|
kernel event node) but also the configuration options. If an option is
|
||||||
|
"n/a" it does not exist on this device. Otherwise, the tool will show the
|
||||||
|
default configuration for this device, for options that have more than a
|
||||||
|
binary state all available options are listed, with the default one prefixed
|
||||||
|
with an asterisk (*). In the example above, the default click method is
|
||||||
|
button-areas but clickinger is available.
|
||||||
|
|
||||||
|
Note that the default configuration may differ from the configuration
|
||||||
|
applied by the desktop environment.
|
||||||
|
|
||||||
|
@note This tool is intended to be human-readable and may change its output
|
||||||
|
at any time.
|
||||||
|
|
||||||
|
@subsection libinput-debug-events
|
||||||
|
This is an installed version of the @ref event-debug developer tool. It
|
||||||
|
prints events from devices and can help to identify why a device behaves
|
||||||
|
different than expected.
|
||||||
|
|
||||||
|
@verbatim
|
||||||
|
$ sudo libinput-debug-events --enable-tapping --set-click-method=clickfinger
|
||||||
|
@endverbatim
|
||||||
|
|
||||||
|
See the man page or the @c --help output for information about the available
|
||||||
|
options.
|
||||||
|
|
||||||
|
@section developer_tools Developer tools
|
||||||
|
|
||||||
|
The two most common tools used by developers are @ref event-debug and @ref
|
||||||
|
event-gui.
|
||||||
|
|
||||||
|
@subsection event-debug
|
||||||
|
This is the in-tree version of the @ref libinput-debug-events tool and is
|
||||||
|
linked to allow for easy debugging (i.e. it avoids libtool shenanigans). The
|
||||||
|
code is the same. For debugging, run it against a single device only and
|
||||||
|
enable the --verbose flag. This will print the various state machine
|
||||||
|
transitions in addition to the events.
|
||||||
|
|
||||||
|
@verbatim
|
||||||
|
$ sudo ./tools/event-debug --verbose --device /dev/input/event3
|
||||||
|
@endverbatim
|
||||||
|
|
||||||
|
See the @c --help output for information about the available options.
|
||||||
|
|
||||||
|
@subsection event-gui
|
||||||
|
|
||||||
|
A simple GTK-based graphical tool that shows the behavior and location of
|
||||||
|
touch events, pointer motion, scroll axes and gestures. Since this tool
|
||||||
|
gathers data directly from libinput, it is thus suitable for
|
||||||
|
pointer-acceleration testing.
|
||||||
|
|
||||||
|
@verbatim
|
||||||
|
$ sudo ./tools/event-gui
|
||||||
|
@endverbatim
|
||||||
|
|
||||||
|
See the @c --help output for information about the available options.
|
||||||
|
|
||||||
|
@note The @c --grab flag puts an exclusive @c EVIOCGRAB on the device to
|
||||||
|
avoid interference with the desktop while testing.

/**

@page touchpad_jumping_cursor Touchpad jumping cursor bugs
|
||||||
|
|
||||||
|
A common bug encountered on touchpads is a cursor jump when alternating
|
||||||
|
between fingers on a multi-touch-capable touchpad. For example, after moving
|
||||||
|
the cursor a user may use a second finger in the software button area to
|
||||||
|
physically click the touchpad. Upon setting the finger down, the cursor
|
||||||
|
exhibits a jump towards the bottom left or right, depending on the finger
|
||||||
|
position.
|
||||||
|
|
||||||
|
When libinput detects a cursor jump it prints a bug warning to the log with
|
||||||
|
the text <b>"Touch jump detected and discarded."</b> and a link to this page.
|
||||||
|
|
||||||
|
In most cases, this is a bug in the kernel driver and to libinput it appears
|
||||||
|
that the touch point moves from its previous position. The pointer jump can
|
||||||
|
usually be seen in the evemu-record output for the device:

1640/4681 within a single frame. On this particular touchpad, this would

|
represent a physical move of almost 50mm. libinput detects some of these

|
jumps and discards the movement but otherwise continues as usual. However,
|
||||||
|
the bug should be fixed at the kernel level.

@page touchpads Touchpads
|
||||||
|
|
||||||
|
This page provides an outline of touchpad devices. Touchpads aren't simply
|
||||||
|
categorised into a single type, instead they have a set of properties, a
|
||||||
|
combination of number of physical buttons, multitouch support abilities and
|
||||||
|
other properties.
|
||||||
|
|
||||||
|
@section touchpads_buttons Number of buttons
|
||||||
|
|
||||||
|
@subsection touchapds_buttons_phys Physically separate buttons
|
||||||
|
|
||||||
|
Touchpads with physical buttons usually provide two buttons, left and right.
|
||||||
|
A few touchpads with three buttons exist, and Apple used to have touchpads
|
||||||
|
with a single physical buttons until ca 2008. Touchpads with only two
|
||||||
|
buttons require the software stack to emulate a middle button. libinput does
|
||||||
|
this when both buttons are pressed simultaneously.
|
||||||
|
|
||||||
|
Note that many Lenovo laptops provide a pointing stick above the touchpad.
|
||||||
|
This pointing stick has a set of physical buttons just above the touchpad.
|
||||||
|
While many users use those as substitute touchpad buttons, they logically
|
||||||
|
belong to the pointing stick. The *40 and *50 series are an exception here,
|
||||||
|
the former had no physical buttons on the touchpad and required the top
|
||||||
|
section of the pad to emulate pointing stick buttons, the *50 series has
|
||||||
|
physical buttons but they are wired to the touchpads. The kernel re-routes
|
||||||
|
those buttons through the trackstick device. See @ref t440_support for more
|
||||||
|
information.
|
||||||
|
|
||||||
|
@subsection touchpads_buttons_clickpads Clickpads
|
||||||
|
|
||||||
|
Clickpads are the most common type of touchpads these days. A Clickpad has
|
||||||
|
no separate physical buttons, instead the touchpad itself is clickable as a
|
||||||
|
whole, i.e. a user presses down on the touch area and triggers a physical
|
||||||
|
click. Clickpads thus only provide a single button, everything else needs to
|
||||||
|
be software-emulated. See @ref clickpad_softbuttons for more information.
|
||||||
|
|
||||||
|
Clickpads are labelled by the kernel with the @c INPUT_PROP_BUTTONPAD input
|
||||||
|
property.
|
||||||
|
|
||||||
|
@subsection touchpads_buttons_forcepads Forcepads
|
||||||
|
|
||||||
|
Forcepads are Clickpads without a physical button underneath the hardware.
|
||||||
|
They provide pressure and may have a vibration element that is
|
||||||
|
software-controlled. This element can simulate the feel of a physical
|
||||||
|
click or be co-opted for other tasks.
|
||||||
|
|
||||||
|
|
||||||
|
@section touchpads_touch Touch capabilities
|
||||||
|
|
||||||
|
Virtually all touchpads available now can <b>detect</b> multiple fingers on
|
||||||
|
the touchpad, i.e. provide information on how many fingers are on the
|
||||||
|
touchpad. The touch capabilities described here specify how many fingers a
|
||||||
|
device can <b>track</b>, i.e. provide reliable positional information for.
|
||||||
|
In the kernel each finger is tracked in a so-called "slot", the number of
|
||||||
|
slots thus equals the number of simultaneous touches a device can track.
|
||||||
|
|
||||||
|
@subsection touchapds_touch_st Single-touch touchpads
|
||||||
|
|
||||||
|
Single-finger touchpads can track a single touchpoint. Most single-touch
|
||||||
|
touchpads can also detect three fingers on the touchpad, but no positional
|
||||||
|
information is provided for those. In libinput, these touches are termed
|
||||||
|
"fake touches". The kernel sends @c BTN_TOOL_DOUBLETAP, @c
|
||||||
|
BTN_TOOL_TRIPLETAP, @c BTN_TOOL_QUADTAP and @c BTN_TOOL_QUINTTAP events when
|
||||||
|
multiple fingers are detected.
|
||||||
|
|
||||||
|
@subsection touchpads_touch_mt Pure multi-touch touchpads
|
||||||
|
|
||||||
|
Pure multi-touch touchpads are those that can track, i.e. identify the
|
||||||
|
location of all fingers on the touchpad. Apple's touchpads support 16
|
||||||
|
touches, others support 5 touches like the Synaptics touchpads when using
|
||||||
|
SMBus.
|
||||||
|
|
||||||
|
These touchpads usually also provide extra information. Apple touchpads
|
||||||
|
provide an ellipse and the orientation of the ellipse for each touch point.
|
||||||
|
Other touchpads provide a pressure value for each touch point (see @ref
|
||||||
|
touchpads_pressure_handling).
|
||||||
|
|
||||||
|
Note that the kernel sends @c BTN_TOOL_DOUBLETAP, @c
|
||||||
|
BTN_TOOL_TRIPLETAP, @c BTN_TOOL_QUADTAP and @c BTN_TOOL_QUINTTAP events for
|
||||||
|
all touches for backwards compatibility. libinput ignores these events if
|
||||||
|
the touchpad can track touches correctly.
|
||||||
|
|
||||||
|
@subsection touchpads_touch_partial_mt Partial multi-touch touchpads
|
||||||
|
|
||||||
|
The vast majority of touchpads fall into this category, the half-way
|
||||||
|
point between single-touch and pure multi-touch. These devices can track N
|
||||||
|
fingers, but detect more than N. For example, when using the serial
|
||||||
|
protocol, Synaptics touchpads can track two fingers but may detect up to
|
||||||
|
five.
|
||||||
|
|
||||||
|
The number of slots may limit which features are available in libinput.
|
||||||
|
Any device with two slots can support two-finger scrolling, but @ref
|
||||||
|
thumb-detection or @ref palm_detection may be limited if only two slots are
|
||||||
|
available.
|
||||||
|
|
||||||
|
@subsection touchpads_touch_semi_mt Semi-mt touchpads
|
||||||
|
|
||||||
|
A sub-class of partial multi-touch touchpads. These touchpads can
|
||||||
|
technically detect two fingers but the location of both is limited to the
|
||||||
|
bounding box, i.e. the first touch is always the top-left one and the second
|
||||||
|
touch is the bottom-right one. Coordinates jump around as fingers move past
|
||||||
|
each other.
|
||||||
|
|
||||||
|
Many semi-mt touchpads also have a lower resolution for the second touch, or
|
||||||
|
both touches. This may limit some features such as @ref gestures or
|
||||||
|
@ref scrolling.
|
||||||
|
|
||||||
|
Semi-mt are labelled by the kernel with the @c INPUT_PROP_SEMI_MT input
|
||||||
|
property.

@subsection touchpads_external External touchpads
|
||||||
|
|
||||||
|
External touchpads are USB or Bluetooth touchpads not in a laptop chassis,
|
||||||
|
e.g. Apple Magic Trackpad or the Logitech T650. These are usually @ref
|
||||||
|
touchpads_buttons_clickpads the biggest difference is that they can be
|
||||||
|
removed or added at runtime.
|
||||||
|
|
||||||
|
One interaction method that is only possible on external touchpads is a
|
||||||
|
thumb resting on the very edge/immediately next to the touchpad. On the far
|
||||||
|
edge, touchpads don't always detect the finger location so clicking with a
|
||||||
|
thumb barely touching the edge makes it hard or impossible to figure out
|
||||||
|
which software button area the finger is on.
|
||||||
|
|
||||||
|
These touchpads also don't need @ref palm_detection - since they're not
|
||||||
|
located underneath the keyboard, accidental palm touches are a non-issue.
|
||||||
|
|
||||||
|
@subsection touchpads_pressure_handling Touchpads pressure handling
|
||||||
|
|
||||||
|
Pressure is usually directly related to contact area. Human fingers flatten
|
||||||
|
out as the pressure on the pad increases, resulting in a bigger contact area
|
||||||
|
and the firmware then calculates that back into a pressure reading.
|
||||||
|
|
||||||
|
libinput uses pressure to detect accidental palm contact and thumbs, though
|
||||||
|
pressure data is often device-specific and unreliable.
|
||||||
|
|
||||||
|
@subsection touchpads_circular Circular touchpads
|
||||||
|
|
||||||
|
Only listed for completeness, circular touchpads have not been used in
|
||||||
|
laptops for a number of years. These touchpad shaped in an ellipse or
|
||||||
|
straight.
|
||||||
|
|
||||||
|
@subsection touchpads_tablets Graphics tablets
|
||||||
|
|
||||||
|
Touch-capable graphics tablets are effectively external touchpads, with two
|
||||||
|
differentiators: they are larger than normal touchpads and they have no
|
||||||
|
regular touchpad buttons. They either work like a @ref
|
||||||
|
touchpads_buttons_forcepads Forcepad, or rely on interaction methods that
|
||||||
|
don't require buttons (like @ref tapping). Since the physical device is
|
||||||
|
shared with the pen input, some touch arbitration is required to avoid touch
|
||||||
|
input interfering when the pen is in use.
|
||||||
|
|
||||||
|
@subsection touchpads_edge_zone Dedicated edge scroll area
|
||||||
|
|
||||||
|
Before @ref twofinger_scrolling became the default scroll method, some
|
||||||
|
touchpads provided a marking on the touch area that designates the
|
||||||
|
edge to be used for scrolling. A finger movement in that edge zone should
|
||||||
|
trigger vertical motions. Some touchpads had markers for a horizontal
|
||||||
|
scroll area too at the bottom of the touchpad.

|

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.

|
|

To fix the touchpad you need to:
|
|
||||||
|
|
||||||
#. measure the physical size of your touchpad in mm
|
|
||||||
#. run the ``libinput measure touchpad-size`` tool
|

#. 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.

||||||
...
|
|
||||||
|
|
||||||
Move the finger around until the detected axis range matches the data sent
|
|
||||||
by the device. ``Ctrl+C`` terminates the tool and prints a
|
|
||||||
suggested hwdb entry. ::

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
|
|
||||||
advertises and what what the touchpad sends, the hwdb entry should be added to the
|
|
||||||
``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.

|
|
||||||
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::
|
|
||||||

|
||||||
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.

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.

|
|

|
|
||||||
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.

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.

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.

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.

||||||

|

|
|

}
|
|
||||||
|
|
||||||
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.

||||||

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).

------------------------------------------------------------------------------
|
|
||||||
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.
|
|
||||||
|
|
||||||
|
|
||||||

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.

------------------------------------------------------------------------------
|
|

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).

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.

|
|

|
|

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 dilligence
|
|
||||||
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/

------------------------------------------------------------------------------
|
|

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=....

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``

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
|

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 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``
|
|
||||||
|
|
||||||
|
|
||||||

==============================================================================
|
|
||||||
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 deboucing 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.

debouncing detection. Please :ref:`file a bug <reporting_bugs>` if that

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.

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.

|
|
||||||
|
|
||||||
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.

|

|

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

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

**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.

|
|
||||||
|
|
||||||
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>`.

|
|
||||||
|
|
||||||
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.

In the illustration above the red area marks the proximity area around the

|
|
||||||
click a single-finger click rather than a two-finger click.

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
|
|
||||||
treated like traditional touchpads.
