If your graphics cards have a high number of brightness levels, chances are the problem is related to https://bugs.launchpad.net/ubuntu/+source /gnome-power-manager/+bug/289520. Although that particular bug has been fixed, the problem is still in effect when adjusting the brightness with the keyboard. A patch to the karmic g-p-m is attached, which might fix the problem for you. It can be installed from the mactel repository also (2.27.5-0ubuntu2~mactel1). Visit https://launchpad.net/~mactel- support/+archive/ppa for details.
