I've been keeping an eye on this too. Every now and then X11Free
cores/crashes on me, leaving the console completely black. If I try to
start X again it hangs in some already probing, and nothing seems to
restore the console to text or X. Reboot is in order, and I don't like
rebooting :)

Perhaps too much of a special case... :)
