For some reason, I can boot into the Live environment just fine, but when I install Ubuntu and actually try to boot into it, I start getting problems. Apparently it has issues going into the login screen, because the entire screen is either black or gray, except for a very slim row at the top where I can see my mouse if I move it up there. However, everything else is pretty much broken. I am wondering why this is happening when I can run the Live environment just fine, and what I can do about this...?

Side note: Fedora 16 works perfectly well. I was looking into switching back to Ubuntu because of a few things in Fedora that recently bug me, but I can't do that if Ubuntu won't even work on my system.
