[Forgot to do reply all]

I think thats to run it in a TTY? I'm running it in X11 mode in virtualbox, 
and my live cd user is using it in X11 mode. The Wayland compisitor, and the 
QT Wayland app started in virtual box, But the default clients aren't I think 
because of Mesa and EGL. (although the Nouveau user is also getting a garbled 
screen with no clients running)
