Since Linux Kernel 3.2, multitouch devices are handled by the hid-multitouch module.
Thus, normally, the touchscreen device of a pc is supported by the newest kernels. To verify that, you have to use the xinput command via bash and obtain a result like the following.
[email protected] ~ $ xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=12 [slave pointer (2)]
⎜ ↳ ELAN Touchscreen id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Integrated Camera id=8 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
↳ ThinkPad Extra Buttons id=13 [slave keyboard (3)]
where the highlighted row show that the pc has an ELAN Touchscreen.
DISABLE THE DEVICE
Now if you want to disable this device, maybe to increase the battery life, you have to digit
In this case
xinput -disable "ELAN Touchscreen"
ENABLE THE DEVICE
Now if you want to re-enable this device (in my case the kernel automatically identified and enabled this device during the installation of the OS) you have to digit
In this case
xinput -enable "ELAN Touchscreen"
Thats all! GWH!
