I am an experienced system builder but Linux and LinuxMCE is a new experience so forgive my ignorance.
After MCE starts and you are presented with the green setup options, the process works fine until you select the type of audio connection. When you have done this, setup restarts with the picture 4x the size it should be leaving only the top left of the screen visible. If you just hit enter a few times it obviously moves through the setup process and arrives at the MCE setup desktop which is sized almost correctly, but the image quality is really bad (very grainy, text is very crude). I am assuming that there is some issue with the graphics driver. Our test machine has an 8600GT card in it. Nvidia do drivers for Linux. Should I attempt to use these?
