touchpad not working after update

[chiara darcangelo]

After an update, the touchpad is not working anymore. It is totally unresponsive. The mouse connected with a wifi is working fine. If I start the system with the Kernel 3.13 0-88 the touchpad is working, but with the kernel 3.13 0-105 it is not, I cannot even find the touchpad in cat /proc/bus/input/devices.

I hope you can help me !

I installed the Kernel 4.2.0 and everything is working super nice now !

Can you see if this bug also happens with the 3.13.0-106 kernel? It can be downloaded from:
