 ==Script to switch between Internal, VGA and S-video==
 This highly overdone script allows to switch between all combinations of Internal, VGA and S-video out. VGA and and S-video at the same time are not allowed on my hardware (I have a T41 with Radeon 7500), so I masked these combinations out. Instead of disabling the internal display with xrandr, I turn off the backlight. One of the allowed combinations is all displays off, and xorg crashes if turning off all displays with xrandr. The script depends on the debian package acpi-support, which is also found in ubuntu and crunchbang (which is what I am using). The dependency can easily be broken out though. Can easily be modified to fulfill other needs, i.e. if you turn off your backlight with something else than radeontool. There is also an OSD displayed in the upper left corner of all active displays.

 If neither VGA nor S-video are connected, the script will only flip on and off the backlight. If one output is connected, be it VGA or S-video, the sequence will be 1) Internal, 2) VGA/S-video (backlight off), 3) Internal+VGA/S-video, 0) all off. If both a monitor and a TV are connected, the sequence will be 1) Internal, 2) VGA (backlight off), 3) Internal+VGA, 4) S-video (backlight off), 5) Internal+S-video, 0) all off.
