I have been having the same problem as the rest of you both on the live cd and after installing. To get to a console, press CTRL + ALT + f9 (unusual i know). the user is root with no password. Having looked at the xorg.conf in /etc/X11, i couldn't make head nor tail of it, especially since there isn't a decent text editor installed, only the godawful vi and vim. Just before I gave up however, I thought "why don't I try deleting it and see whether starting X will create a new one?". Bingo, it worked.
