This problem has happen to me 3 times. I have 2 installs of Ultimate Edition one I installed kde the other I didn't. On the Gnome only one I have no graphical sun rise, and I get this ugly 10.10 ubuntu boot up screen. Then what looks like a terminal full screen or Dos. If that didn't make sense I'll make a video. The same thing happens in the kde but it at least look "good" during boot up. I don't know what the username and password is what is it? It's not what I made it during the install.
So what is the username and password because mine's not working?
