Only, like every fifth restart is my touchpad found by Ubuntu 11.10. I suspect this might be a hardware failure, but I'm not sure so i throw this question out here. I don't run Windows on this computer so can't check like that.

Anyway, the computer is a Dell Vostro 1310 and the touchpad is an "AlpsPS/2 Alps GlidePoint". If I check the /proc/bus/input/devices file the touchpad is only listed those times it works. Otherwise it's not visible in this file. Any clue?

To me it certainly sounds like hardware related. Maybe some loose wiring? or maybe your touchpad has a physical button that disables it that you happen to switch?

If the wiring was loose, I would except it to sometimes stop working when the computer is started. But I can have the computer started for a whole day and the trackpad works all the time. And the same goes for the theory of me accidentally pressing a button... :-/ –  Niclas Nilsson Apr 12 '12 at 8:12
