s-video/composite on ubuntu 11.10


New Beagle Board owner here, trying to set up the s-video/composite
commands, using Ubuntu 11.10 that I downloaded using the netinstall

By modifying the bootargs as found online, I am able to get svideo/
composite signal initally (colors displayed), then during the initial
boot-up it shows text, but then as it is loading the UI, the screen
goes black. The device is still functioning as I can connect via the
serial port.

Am I perhaps using too new of a linux kernel that has yet to support


So I still can't really do this with the bootargs, however this is
working for some reason:

First, in my boot script, I set the DVI resolution to 640x480:
  setenv dvimode 640x480MR-16@60

Then, once the x-server started, as root I ran from the terminal:

echo "0" > /sys/devices/platform/omapdss/overlay0/enabled
echo "tv" > /sys/devices/platform/omapdss/overlay0/manager
echo "50,35" > /sys/devices/platform/omapdss/overlay0/position
echo "1" > /sys/devices/platform/omapdss/overlay0/enabled
echo "0" > /sys/devices/platform/omapdss/display0/enabled
echo "1" > /sys/devices/platform/omapdss/display1/enabled

This website was helpful: http://omappedia.org/wiki/Bootargs_for_enabling_display

Fortunately, this method appeared to have no overscanning issues.
Unfortunately, trying to have two overlays for fb0 and sending them to
overlay0 (for "lcd") and overlay1 (for "tv") caused the system to
crash. Perhaps there is a way to show images on both ports?
