I'm trying to get a signal on the S-Video output of the Beagle. I use
the script below to make /dev/fb0 appear on overlay1 and have overlay1
go to the tv manager. The project being driven by this sees there is
an S-Video signal, but it only displays black.
I'm running the 2.6.32 kernel from http://www.angstrom-distribution.org/demo/beagleboard/
Any idea how to fix this?
