** Description changed: 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. + Some trials: the problem should be on i915 driver even in single user mode.
