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. --- ApportVersion: 2.12.5-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: john 1776 F.... pulseaudio /dev/snd/controlC1: john 1776 F.... pulseaudio DistroRelease: Ubuntu 13.10 InstallationDate: Installed on 2014-02-10 (1 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: Apple Inc.
