Great. If you're using use_gmux=1, you most probably unloaded and
reloaded the driver with the new option. Then, gnome-power-manager still
uses its previous settings. In order to get more appropriate settings,
you also have to kill and restart gnome-power-manager. What happens
then? Does the backlight change? Does gnome-power-manager employ a
reasonable step size?

Bug description:
After updating mbp-nvidia-bl-dkms 0.24.3~lucid to 0.25~lucid, backlight control is broken on MacBook Pro 6,2.
- Control keys to adjust brightness do not work anymore
- When unplugging the MacBook Pro from its power supply, the backlight is completely dimmed. Re-plugging the power supply restores the brightness to the value as it was before the laptop was unplugged.
- When the laptop is disconnected from its power supply and is booted, screen brightness is normal but not adjustable.

Running Ubuntu Lucid 64bit with generic kernel 2.6.32-25-generic.44
Using NVIDIA current drivers (195.36.24-0ubuntu1~lucid)
nvidia-bl-dkms is not installed as the backlight is steered by the Intel graphical adapter on the MacBook Pro 6,2
