Steps to reproduce: 1. Start XFCE 2. Click "Exit", select "Turn off computer", click "OK" What happens: XFCE puts you in virtual terminal 1, while outputting into VT 7 (or whichever VT XFCE was running in) What should happen: XFCE should switch and output text in VT 1.
Xfce doesn't do anything. It's an X configuration issue. Try asking on your distributions mailing list.
