In my case - Kubuntu 12.04- I have quite similar problems. At present I
need to reset the system at least once a day. Often the system "freezes" to
such an extend, that I can simply not move any more anything  - no cursor,
no mouse click, nothing.  in such circumstances, I simply need to turn of
and turn on the PC in order to get the system movable again.

Respectfully yours,
