Title:
  [MacBook Air 6,2] screen backlight brightness and keyboard light turn
  into fully-on after Grub boot with i915 driver

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Problem: Both the screen backlight brightness and keyboard light are
  turned on during the booting as tested on ubuntu 12.04.3, 12.04.4, and
  13.10. Due to installation problem on 12.04, it's only tested with the
  live system.

  What's expected: the brightness state before booting is preserved.

  Some trials: the problem should be on i915 driver even in single user
  mode. Tried "nomodeset" kerenel arguement can avoid the problem, but X
  will fail to start.
