[[!meta title="How to disable the touchpad in Xorg with xinput"]]
|
||
|
|
|
||
|
|
If you, like me, think that evdev and xinput should somehow help you
|
||
|
|
to disable the touchpad without the need of some daemon or gui tool,
|
||
|
|
you're right!
|
||
|
|
|
||
|
|
Having a look at the output of **xinput list** is already looks promising:
|
||
|
|
|
||
|
|
[18:11] kr:~% xinput list
|
||
|
|
⎡ Virtual core pointer id=2 [master pointer (3)]
|
||
|
|
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
|
||
|
|
⎜ ↳ Macintosh mouse button emulation id=7 [slave pointer (2)]
|
||
|
|
⎜ ↳ TPPS/2 IBM TrackPoint id=8 [slave pointer (2)]
|
||
|
|
⎜ ↳ SynPS/2 Synaptics TouchPad id=9 [slave pointer (2)]
|
||
|
|
⎣ Virtual core keyboard id=3 [master keyboard (2)]

Having a deeper look at device 9, the touchpad, with **xinput list-props 9**
|
||
|
|
reveals an interesting setting:
|
||
|
|
|
||
|
|

If you expect something like **xinput set-prop** even without
|
||
|
|
reading the manpage, you are right:
|
||
|
|
|
||
|
|
[18:12] kr:~% xinput set-prop 9 125 0
|
||
|
|
|
||
|
|
This disables the touchpad and can be integrated into .xinitrc very well!
