  hang

Bug description:
  I am fairly frequently (maybe once every 2 days) seeing screen
  lockups.  The system is fine, and then screen locks up. mouse is still
  movable and even changes icon based on content under it (ie mouse over
  link changes to pointing hand).  Programs are still running (often
  this occurs during a google hangout, and the hangout, audio and mic
  seem to work fine).

  Today when this happened I had more patience and hit ctrl-alt-f1, and then subsequently saw that dmesg had:

  Normally, I'm generally able to switch consoles in and out of X
  without problem. I do not know if the above trace is related to X
  being locked or not.

  I'll also attach the /var/log/Xorg.0.log.old that had some information
  in it also andapparent segfault.  That said, I think all log
  information is tens of seconds after the lock up and might be a result
  of me ctrl-alt-1 <-> ctrl-alt-f7 while system was in a borked state.
