I just learned the hard way and figured I'd tell people...
X will not start and you will not get the cursor.
...time to go fix it.
Fixed; if you already did this:
1) ctrl+alt+f2
2) login as root
3) cd /usr/share/fonts/X11/misc/
4) rename cursor.pcf.gz-artwiz to cursor.pcf.gz
5) apt-get remove --purge xfonts-base
6) apt-get remove --purge artwiz-cursor
7) apt-get instlal xorg
8) /etc/init.d/gdm stop
9) gdm
should be working again.
