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.
