Forgot about that, but yes, it only works as root also for me.
Switching ttys in the console should work with only Alt-Fn, no control.
Look in your /etc/X11/XF86Config-4 and see if you have a SERVERFLAGS section
with an entry
Option "DontVTSwitch" "true"
If you have then remove it, and if you don't try adding
Option "DontVTSwitch" "false"
and see if it works (you may need to add the serverflags section for this).
