Soon after the installation the touchpad is not working at all, it just randomly move here and there sometime, else nothing. 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!
