["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Tony Primerano, in Windows, does it show an error in device manager
before you plug anything in (i.e. onboard hardware is broken) or is this
something external to your PC (ex. HDMI cord, and/or monitor)?

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.
