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?
