the touchpad doesn't work at all, in settings it says "no touchpad found"

[Aleksandar Babic]

I have checked the input devices via terminal with cat /proc/bus/input/devices and didn't find the touchpad. Using internet I found out that it can only be a bug in linux kernel. The touchpad doesn't react at all.
