Indium,

Two days ago, a new version was released (0.25.1~maverick). This fixes
the blank screen and reenables controlling the backlight with F1 and F2.
However, you have now only 8 instead of 15 steps to control the
brightness.

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
