  As of Ubuntu 16.04 display stays black after resume

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Computer: Macbook Pro Retina 2013 (core i5 with Intel HD Graphics)

  Unexpected behavior: After resume, the display stays black. This
  behavior was not observed with Ubuntu versions up to 15.10, including
