Touchpad movement doesn't work after suspend

[svenmeier]

Once or twice a week *after* resume from suspend I can no longer use the touchpad to movethe mouse pointer, mouse clicks are registered though.

Reloading module psmouse works as a workaround.

install evtest, and when it happens next time, switch to a VT and run evtest on the touchpad device to see if the kernel sends events

[svenmeier (sven-meiers)]

It seems all events are still correctly recognized by xorg.

[svenmeier (sven-meiers)]

After switching back into Gnome session touchpad movement works again. Thus I suspect this to be a Gnome problem.
