I cannot exit X. I installed xorg. I can get in okay but I can't exit. I tried Ctl-Alt-Backspace, Ctl-Alt-F1, exiting the window manager.
When I use Ctl-Alt-Backspace the screen blanks and goes into power save mode. Nothing I can do gets the screen back. I tried Ctl-Alt-F1-8
Ctl-Alt-Del reboots the machine.
I have tried this with twm, Gnome and xfce.
