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


If that does not help you, start a new thread and post the keyboard
section of your /etc/X11/xorg.conf.
