Title:
  [HP ProBook 455 G1] Display blank after resume (consistent)

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  With the hardware as shown in automatically attached files (HP ProBook
  455), display never recovers from resume, although the computer works
  fine otherwise (it can be connected to over ssh, in particular). I
  disabled the discrete GPU BIOS (that is the current stand) but the
  problem remains. Contrary to #1010683, where some people were helped
  by using "pm-suspend --quirk-test --quirk-s3-mode", this problem is
  exhibited without discrete graphics (thus ruling out problems with
  vgaswitcheroo).

  WORKAROUND: Install fglrx or fglrx-updates.
