@page udev_config Static device configuration via udev
|
|
|
|
libinput supports some static configuration through udev properties.
|
|
These propertiesare read when the device is initially added
|
|
to libinput's device list, i.e. before the @ref
|
|
LIBINPUT_EVENT_DEVICE_ADDED event is generated.
|
|
|
|
The following udev properties are supported:
|
|
<dl>
|
|
<dt>LIBINPUT_CALIBRATION_MATRIX</dt>
|
|
<dd>Sets the calibration matrix, see
|
|
libinput_device_config_calibration_get_default_matrix(). If unset,
|
|
defaults to the identity matrix.</dd>
|
|
<dt>ID_SEAT</dt>
|
|
<dd>Assigns the physical seat for this device. See
|
|
libinput_seat_get_physical_name(). Defaults to "seat0".</dd>
|
|
<dt>WL_SEAT</dt>
|
|
<dd>Assigns the logical seat for this device. See
|
|
libinput_seat_get_logical_name()
|
|
context. Defaults to "default".</dd>
|
|
<dt>MOUSE_DPI</dt>
|
|
<dd>HW resolution and sampling frequency of a relative pointer device.
|
|
See @ref motion_normalization for details.
|
|
</dd>
|
|
<dt>MOUSE_WHEEL_CLICK_ANGLE</dt>
|
|
<dd>The angle in degrees for each click on a mouse wheel. See
|
|
libinput_pointer_get_axis_source() for details.
|
|
</dd>
|
|
</dl>
|
|
|
|
Below is an example udev rule to assign "seat1" to a device from vendor
|
|
0x012a with the model ID of 0x034b.
|
|
@code
|
|
ACTION=="add|change", KERNEL=="event[0-9]*", ENV{ID_VENDOR_ID}=="012a", \
|
|
ENV{ID_MODEL_ID}=="034b", ENV{ID_SEAT}="seat1"
|
|
@endcode
|
|
|
