I have also been affected by this bug several times in both Intrepid (32-bit) and Jaunty (64-bit) on a Macbook 4,1. There seems to be more then one way to reproduce this bug, though I've had trouble reproducing it. It happens sometimes when the screen reduces brightness to save power, when you move the mouse it should increase brightness again but sometimes it will remain stuck at zero.
Something else that might be worth noting. I ran into the bug after using ctrl+alt+backspace once and when I was trying to hit restart I accidentally went to hibernate. When it woke back up the brightness was still stuck at 0%, but when I logged in an Gnome started the brightness increased. That was the first time I've seen the brightness unstick itself as usually it takes a full reboot just restarting X does not help. When I logged back out of X though the brightness was stuck at 0% on the login screen. I thought this behavior was especially odd. Is there anything else I can do to help debug this? This bug is very frustrating and is considered top priority as it has happened enough times to cause a serious nuisance.
