When booting up on my old laptop (Dell Latitude D610) it gets all the way through to the graphics phase, but I don't see anything on the screen. There is something there because when I switch to the first VC I see on the screen (very briefly) what I think is the KDE desktop. I don't see it long enough to know for sure. I have tried restarting the graphics phase, but it doesn't seem to help.

Any suggestions?
