Beagleboard XM rev c and Linux

[mdrouillard]

Folks, we have just picked up a Beagleboard XM rev 3 and we are trying to get a version on Linux (Ubuntu) to work on it. Has anyone out there a good recipe to get this to work? At this point the demo distribution works, and we are able to connect the machine to a keyboard/mouse, the net, and a HD television, but when we try to boot a Ubuntu distribution that reportedly is designed for the board (on a different SD card ofcourse) we don't get any video output to complete the installation. It may be working, but without a screen to watch the progress we are literally runnng blind. Any help the community could offer would be greatly appreciated. I am sure we are missing something "easy" but for all the googling I have done, I can't seem to find the answer.

What distribution are you running? (download link?)
How to get the hdmi or svideo output to wake up like it does in the demo distribution?

Many thanks everyone.
