I can't log in to tty1-6!

[Matheson]

Hey,   I turned on my computer today, and I can only log in to X, not the normal tty's.  I hanve no idea what could have happened.  When I try to log on it says       Last login: Wed Oct 11 00:23:41 2000 on tty1       Debian/GNU Linux 2.2 tux tty1     tux login:   Any clues?   Thanks, Cameron Matheson
