Title:
  Periodically video will freeze for no reason at all and no specific
  time between freezes.

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This has been going on for over a year. It doesn't matter if I have
  any applications open such as Evolution or Firefox. It could happen
  any time during the day when I'm working on the computer or during the
  night when its' the most idle. Once the video freezes the cursor can
  still be moved around the desktop however clicking on anything does
  not work. During this time all background process and cronjobs
  continue to run.

  Running the command listed below:

  chris@localhost:~$ cat /proc/version_signature > version.log
  cat: /proc/version_signature: No such file or directory

  Of course what I expect to happen is the video to not freeze every so often.
  What happened is that the video froze.
