[ubuntu] Laptop brightness always reset to 100% at boot

view story

http://ubuntuforums.org – This is just an annoying little bug that I'm having. Every time I reboot my system, brightness is restored to 100% and stays that way until I manually lower it down using my brightness keys. 100% brightness is blinding, and while it's not a major issue, it's still annoying to have to do this manually. Laptop: Dell Studio 1555 Graphics: ATI Mobility Radeon HD 4570 (w/ fglrx proprietary drivers) I have "noapic" added on the kernel boot options, but I don't think that's what causes the issue, as I can't change brightness at all without it (which is even worse).
