My touchpad sometimes works, and sometimes not. The touchpad buttons always work though, and usb mouse always does.

I think this log in the /var/log/Xorg.0.log file is relevant:

(WW) AlpsPS/2 ALPS GlidePoint can't grab event device, errno=16

Anytime the touchpad does not work, I get this error in the log file. I have the feeling is related to the event number assignation, as shown in the logfile:

(**) Option "Device" "/dev/input/event9"

I think it could be related to conflictive event assignment, so maybe the touchpad event is sometimes blocked by another device grabbing the event. In any case, sometimes when it is not working, it is linked to event 9 and sometimes to other event numbers.

How could I check the current device VS event assignment ? I think that information may help us.
