I installed ubuntu server on a computer and it seems to work fine, I can ssh into it and everything but I can't understand anything that appears on the screen. It has a white background and instead of normal characters it just shows garbage text.
This is a picture of the screen
This is a video of the computer starting if that helps http://www.youtube.com/watch?v=kw3VKIpqCXw
Does anybody know why this is happening?
