http://askubuntu.com – I recently bought a used computer and was told it had windows vista. It was bought on a trust factor and I got shafted. The computer turns on and displays fine through my hdmi connection. I was told by a friend that the os displayed on my screen is ubuntu, however my mouse stays locked in the center of the screen and no keyboard commands seem to function. The computer seems solid enough. I can even see the clock on my screen keeping time. The computer during start up won't even recognize your f commands as in entering bios or set up type functions. I believe my usb drivers are working b (HowTos)
