Comment 30 for bug 374459

ok, I'd need to you to do the following:
tail -f /var/log/Xorg.0.log (assuming this is your running X.log)
tail -f /var/log/messages

then switch the touchpad off and on again. wait until you see something in messages about the device being there again, at this point the X log should print a message too ("touchpad found"). Once this message is printed, does the touchpad work? unfortunately, the touchpad driver isn't very chatty and doesn't print much when the connection is lost.
