Title:
  A long power key press results in lit black screen [arale]

Status in unity8 package in Ubuntu:
  Incomplete

Bug description:
  vivid-proposed #175 arale
  [ editor's note: the power notification dialog not appearing is being tracked in bug 1446298, this bug is now just about the screen not coming on correctly, krillin and mako do result in screen coming on ]

  
  Steps:
  - short press the power key to blank the display and lock the device
  - then long press the power key continuously

  expected: display on showing the power off notification

  On Arale
  actual: display on, black

  
  On Arale
  Other interesting bit, if i run phablet-screenshot (mirscreencast) it shows the greeter w/ no power dialog (see long_press1.png attached)
  If i wait for the backlight to time out once again, and repeat the long keypress, run phablet-screenshot (mirscreencast) is shows the greeter - but with the power dialog this time (see long_press2.png attached)

  also, if i hit vol+/- simultaneously to get a shell screen shot, i see
  the corresponding images captured greeter no power notif on long
  press1, but then greeter with power notif on long press 2
