Title:
  backlight does not turn back on after resume

Status in The Linux Kernel:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  to reproduce:

  suspend my samsung series 9 with i915 graphics, core i5...

  then resume.

  expected result: backlight turns on

  current result: laptop resumes, and does stuff, but you can't see
  anything (except very faintly in the right light). you can type in
  your password blind to get past the the screen lock, and then the
  laptop will respond to brightness up/down keys, which wakes the
  backlight out of its stupor.
