Bug description:
  Display backlight turns back on almost immediately after being turned
  off.

  In theory DPMS support has landed in XMir, but it's not really
  working.

  TEST CASE:
  xset dpms force off
  Expected: Screen turns off and stays off
  Observed: Screen turns off and then immediately either:
    (a) turns back on fully; or
    (b) the backlight turns back on but the screen remains black.
