Generally these types of issues should be analyzed as gnome-power-
manager issues first, then driver issues if g-p-m can be ruled out.

It's possible g-p-m is simply not tracking your backlight settings
correctly, or not  updating them properly on reboot.

** Package changed: xserver-xorg-video-intel (Ubuntu) => gnome-power-
manager (Ubuntu)

Title:
  LCD backlight level is reset to maximum after a reboot.

Status in “gnome-power-manager” package in Ubuntu:
  New

Bug description:
  Happened on the latest Ubuntu Precise on MacbookAir 4,1.

  I have to adjust the LCD backlight each time Ubuntu is rebooted manually - or the LCD hurts my eyes.
