Define monitor. Do you mean a laptop LCD screen or a external CRT or LCD
display?

Ahh, if you mean the internal panel, there has just been support added
into HAL for the Macbook.... Checks.... Yes, I committed Ryan Lortie's
patch about a week ago. When HAL 0.5.9 is released, then things should
work for you.

No, you want to change the physical backlight brightness, rather than
the GAMMA by the sounds of things.

If you are feeling brave, you could try to build a new HAL from source.
When you've got the new HAL running, gnome-power-manager will just work
- where you can set brightness in the preferences or using the
brightness applet in GNOME 2.18.1.

I hope that helps,

Richard.
