If /usr/bin/Xorg dies, then all subsequent attempts to login fail,
I get the blue-streak-and-stars background image, then "Oh no!
Something has gone wrong. ..." Clicking the LogOut button
just repeats the failure. This behavior persists even after reboot.
How do I clean up so that graphical login can succeed?
