Title:
  HDMI output no longer works after running updates

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  This seems similar to 1496697 but i can't seem to work around the
  issue by booting without the cable plugged in.  Ubuntu stopped
  recognizing my HDMI connected monitor after a regular system update
  reboot.
