xinput is a utility to configure and test X input devices, such as mouses, keyboards, and touchpads. It is found in thepackage.
To list what xinput devices are available, use:
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ DELL0ABC:DE F123:4567 Mouse id=9 [slave pointer (2)] ⎜ ↳ DELL0ABC:DE F123:4567 Touchpad id=10 [slave pointer (2)] ⎜ ↳ PS/2 Generic Mouse id=16 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Video Bus id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ...
device may be identified by its name (
"DELL0ABC:DE F123:4567 Touchpad") or ID (
When being executed in a startup script, it is recommended that you use the name, as the ID may change following a reboot and lead to inconsistencies.
To list all the properties of a device that can be set, use the following command:
$ xinput list-props device
This may yield results like such:
$ xinput list-props "DELL0ABC:DE F123:4567 Touchpad"
Device 'DELL0ABC:DE F123:4567 Touchpad': Device Enabled (179): 1 Coordinate Transformation Matrix (181): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Tapping Enabled (336): 0 libinput Tapping Enabled Default (337): 0 libinput Tapping Drag Enabled (338): 1 libinput Tapping Drag Enabled Default (339): 1 ...
property can be identified using its name (
"libinput Tapping Enabled") or number (
As with devices, it is recommended to use the name in startup scripts, as the ID may change, albeit less often.
Set device properties
Properties of devices can be set one or more (up to three) values. The syntax for setting a property to a value is:
$ xinput set-prop device property values
values is replaced with the value(s) of the property.
For an instance, to enable tapping with the above output. Either of the following commands could be used:
$ xinput set-prop "DELL0ABC:DE F123:4567 Touchpad" "libinput Tapping Enabled" 1
$ xinput set-prop 10 338 1
On success, no output should be produced.
Below are some of the ways xinput can be used.
$ xinput set-button-map mouse-device 1 1 1
The above command will make middle and right mouse button to function like the left button. Putting zeros will disable them.
$ xinput set-button-map mouse-device 1 0 0
