[oooh <oooh.oooh@xxxxxxxxx>]

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.
