toedder: A friend had Ubuntu installed and I couldn't get it to work for him. Now when I install the disk (actually I chose the "try" option, the first thing I get is an error message "Analog Input Cannot display this video mode"

I can see the different pull down menus but if I chose something, nothing happens and the background flickers. It's not an old computer (within 5 years) and runs XP fine. I suppose I have to play with the bios settings or something else over my head?
