Hello,
I installed Ubuntu 16.04 LTS on Lenovo Thinkpad Carbon-6th, Kernal information could be find here [0]. Soon after the installation the touchpad is not working at all, it just randomly move here and there sometime, else nothing. Mouse works absolutely fine.
More information
1. I could find the tocupad-device present in 'cat /proc/bus/input/devices' [1]
2. xinput is given here [2]
3. 'xinput --list-props 12' output is here [3], I tried to change the values but no success unfortunately.
4. I found this wiki (https://wiki.ubuntu.com/DebuggingTouchpadDetection#In_case_your_Touchpad_doesn.27t_work_at_all_.28No_response_from_the_Touchpad.29) and ended up reporting this bug.
5. One last piece of information, somehow I managed to have my touchpad worked absolutely fine during my previous attempt of Ubuntu 16.04 installation this morning.
The only parameters I changed was
xinput set-prop 12 302 1 1 1
xinput set-prop 12 293 40 40 0
I had to discard that installation as there was issue in sudo apt-get update, it failed to get the package, which seem to be linked with the wifi issue. So I connected to proper wifi and tried fresh installation and ended up loosing my stable touchpad.
I would really appreciate any help in fixing this problem. Many thanks for your time!
Best Regards
Pooja
