Hi, 

I'm having the exact same issue on Ubuntu gutsy and hardy with the same
AOpen Mini PC. Hardy uses the 2.2.0 tag. Which should include those fixes.
Video comes on during boot on TV if nothing else is connected, but as soon
as the x drivers init, screen turns of. 

According to log, everything seem to have gone allright, and X has been
started, but as said, there is no output on the SVIDEO/COMPOSITE or
COMPONENT outputs.

Some friends of mines have been able to get the exact same type of Mini PC
to display with ubuntu gutsy. I've tried with exact same drivers/xorg.conf
with not luck. One potential issue could be that this system have been
booted with windows on it, so maybe it has changes something in the display
driver.

I've supplied xorg.conf, log and xrandr outuput. Hopefully this could give
somebody an idea

The fix for ignoring the LVDS output on these mainboards doesn't seem to be
working either. It's still listed by xrandr if you don't ignore it in
xorg.conf
