Bug Description
Sometimes, in my Ubuntu 12.04 system on Toshiba AC100 (ARM), the touchpad doesn't react to movements anymore: i.e., I move the finger, but the pointer doesn't move (it is even being hidden because there are no movements).
The buttons under the touchpad do work.
Also, when I switch windows etc. the pointer does appear, and then hides again. So it's not a problem of the pointer in X, it's a problem either of the touchpad physically, or of the driver for it.
I usually notice this when I'm working with a browser (Firefox), perhaps even with a map (like Google map) inside it. But this may be not related to the causes of the bug.
A workaround: attach a USB mouse. (It works.)
As I've found out somewhere under /sys/, the device is an Elantech touchpad, and the corresponding driver is psmouse.
I couldn't find anything relevant in the dmseg output.

Perhaps, you'll find something in my dmesg.
It happened about an hour before I'm submitting this bug report (right before I attached an external USB mouse, which you can see in the dmesg).
