How reproducible:

Second time within a day, no clear path how to get there.

Steps to Reproduce:
1. Compiz is on (with the experimental driver)
2. this time I was moving from desktop to another, not doing anything special I could remember.
3. Not really reproceable.
  
Actual results:

Screen got stuck. Yesterday the whole kernel got stuck after pressing ctrl-alt-F2 to enter vt2. This time it does not take the keyboard input.

Expected results:

not to get stuck....
