That should be Ctrl-Alt-Backspace

It sounds like you are having some keyboard configuration problem. Is it a
standard keyboard, are you using any language extensions, did you chose
us-enlish keyboard on debian setup or somethings else?

If you run xev under X what does it show for control and for alt? (it doesn't
catch Ctrl-Alt-Fn for me).

Also when running showkey in the console what does it show when you press
Ctrl-Alt-f1 and Alt-f1 ? (to exit showkey just wait ten seconds without pressing
anything).
