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

Status in gnome-power-manager 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.
