I would suggest you "apt-get install xserver-xfree86" and make that your default X and see if that fixes things. If it does we know it is x.org.
This is very bad advice. xfree86 is abandoned and lacks a number of patches which have subsequently been applied to x.org.
If not then it is something else. Something you might also try is to open an xterminal and try to kill your display manager and X, to see if you get your terminals back. Or try it from the remote connection. If none of that works try posting your ps list and X log.
By display manager he means either 'gdm' or 'kdm'. In a stock Debian install that will be 'gdm'.
