My touchpad seems like PS/2Generic Mouse device with the output xinput. I cannot set it correctly albeit I gave some tries. In addition its multitouch functions do not work becasue of this detection issue.
Here is the output of xinput list
Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=10 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=11 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=15 [slave pointer (2)]
⎣ ...
In addition, the problem occured after I tried to activate right click of my touch pad with following command from Synaptic touchpad right-click not working
sudo su
echo options psmouse proto=exps > /etc/modprobe.d/psmouse.modprobe
reboot
How can I check all the problems out and get my touchpad working all correctly?
