I have for a while been trying to get TV out to work on a PC running Mythbuntu. I spoke to Dave at the Linux Expo a couple of weeks ago, who mentioned xrandr to me.
It turns out that it was already installed in Mythbuntu. I managed to play with the settings in Mythbuntu and got the TV out to work, sort of, as a separate X display. But the display on the TV is black and white, not colour, and it only shows the XFCE logo in the middle and some default desktop icons on the left. I can move the mouse from the monitor to the TV okay and open the icons on the TV desktop. I also tried a different s-video cable, but it made no difference. I then managed to get the TV out to be a clone image of the monitor, but still only in black and white. I have upgraded Mythbuntu to 8.10, which seemed to offer better choices/design of the nvidia settings, with the latest drivers. Any ideas how to get the TV out image to be in colour?
