Hi all. I have done some extensive searching and haven't been able to come up with anything to solve this quest yet.

I would like to be able to use my webcam as an ambient light sensor to automatically adjust my backlight brightness on my laptop. I have a Dell XPS M12010, with the Logitech webcam built in. I am running Ubuntu 8.04. My webcam is working and shows up at /dev/video0. I know gnome-power-manager can do this, and I have seen the gconf-editor settings for the ambient light sensor, but when I change these settings nothing happens.

If anybody has some helpful advice, or can point me somewhere else it would be most appreciated!

Thanks!
