I had the opposite problem, and this thread helped me find the fix. On an X300, the internal display was always at maximum brightness every time the internal screen came on (not just on boot, even if just coming out of "turn off the display"). I found the cause (I think) under Hardware and Sound | Power Options | Edit Plan Settings. There under "Power Saver" (the selected plan) brightness is on maximum when plugged in. I turned it down a bit and the screen changed immediately. Not sure if it will stick after shutting down.
I'm wondering why I'd have Power Saver set (probably the default) since I surely don't care about battery life when plugged in? High Performance will drain the battery in a hurry. Is it worth creating a new plan that has the Power Saver settings for battery and the High Performance settings (except maximum brightness ;) for plugged-in?
