Hello, Now I have almost the same problem on another computer. Except that I did not use preupgrate but upgrade via netinstal. The only thing I know the computers have in common is that they are both Dell and have flat screns. One is a desktop, the other a laptop. After it says "Welcome to Fedora", it prints a number of messages most of which just say it's starting something. Then it stops and the screen flickers for a few seconds. The last message is entirely different on both computers, so I am assuming it is not relevant. I don't have access to the desktop computer, but the laptop actually did boot, and I found out I can press Alt-F2 and then log in in text mode. After I logged in, it says: Can not open display "default display" I am assuming its the same with the desktop computer, but can not verify. I found earlier threads describing a similar problem with F12 alpha and beta, but found no solution. Any advice?
