Open a Gnome terminal or an xterm, become root and run
chvt 2
to go to virtual terminal 2, for example. Log in as your normal user, su
to root level and run
/etc/init.d/gdm stop
This will shut down Gnome and X. The command to start it again is
/etc/init.d/gdm start
As far as the ctrl-alt-fx problem is concerned, have a look at this
thread:
http://lists.debian.org/debian-user/2006/04/msg02492.html
If that does not help you, start a new thread and post the keyboard
section of your /etc/X11/xorg.conf.
