Thats the thing. In the Xorg logs it doesn't show up at all. If is
connected Xorg shows no monitors connected at all. I can't find
anything in the Xorg log that references it and no amount of telling it
to ignore EDID will make a signal come out to the TV. Is there a way to
force Xorg to output to the DVI port a specific mode and to not try any
Automagic?
I'll try and get the logs for you, but since I am going to be hooking it
back up, I thought I might have to tricks to try when I do.
