Have you tried using Ctrl+Alt+F2 to get to a text console and logging in 
there?  If that works, try this to see if your display manager is working:

ps aux | grep gdm | grep -v grep

If you're not using Gnome, substitute whatever dm you're using.  I'll 
leave the reason for the second grep as an exercise for the reader.
