Title:
  Backlight level is inconsistent with actual backlight after S3 suspend
  resume

Status in acpi package in Ubuntu:
  New
Status in gnome-power-manager package in Ubuntu:
  Invalid
Status in hal package in Ubuntu:

Status in linux package in Ubuntu:

Bug description:
  Whenever I resume from suspend, my backlight level is at 100%. If I
  make an adjustment to the level using gnome-power-manager it jumps to
  what g-p-m thinks it should be.

  Steps to reproduce:

  1. Decrease backlight level to e.g. 10%
  2. Suspend
  3. Resume

  Expected result: backlight is at 10%

  Actual result: backlight is at 100%, but g-p-m thinks still 10%.
  "Increasing" the brightness with the keyboard sets it to 20%.

  It's possible that this only affects mbp_nvidia_bl

  Linux should resume with the same backlight level it had when it
  suspended, or in any case, g-p-m should not let its internal level go
  out of sync.
