Public bug reported:
I upgraded to 12.10 from 12.04 yesterday. The system has frozen 3 times
since then. The 'freeze' is gradual - at first windows become
unresponsive, or intermittently unresponsive. Then it is not possible to
switch to an alternative window. Then the pointer freezes. It is not
possible to switch to a TTY terminal at this point either.
On one occasion I had a TTY open and was able to see that Compiz was
using 100% CPU. I killed Compiz and, whilst this ruined my desktop
session, the pointer unfroze.
