  Intermittent black screen on HP EliteBook 840 G1

Status in xorg package in Ubuntu:

Bug description:
  Occasionally, the internal laptop display goes black for a few
  seconds, then comes back to life. The external display stays on. It
  looks as if power management were kicking in by error but affecting
  only the internal display.

  When I’m working with the external display, I need to move the mouse
  into the area managed by the internal display to wake it up again;
  else it seems to remain black (though I haven’t tested that behavior

  Most tests with the external display were made with the port
  replicator and an external display plugged into one of the DP ports
  via a DP–DVI adapter. I cannot tell for sure what the behavior is with
  the external display plugged directly into the laptop.

  The hard disk was originally installed with Ubuntu MATE 14.10 in a HP
  EliteBook 6930p, upgraded to 15.04, 15.10 and eventually 16.04 and
  finally moved to the EliteBook 840 G1.
