  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.
