Radeontool

radeontool is a hack to turn on and off the panels background light and external video.

Features

• turn background light on/off
• turn external video on/off

There's also a script called lightwatch.pl available at the project homepage that turns off the background light whenever xscreensaver blanks the screen and back on when unblanked. A more sophisticated version can be found here.

You may need to set up sudo (preferred method) or make the executable setuid root by issuing

# chmod u+s /path/to/radeontool

in order to allow unprivileged users to use it.
