Well, you're right, he did say a "special" user (not the root) ... I see it
now - with nobody logged in at the console:

I didn't want to believe it, but now I see it with my own eyes.  Thank you
all for the info.

Oh.  I still haven't learned where it stores the configuration when it's not
powered up.  I don't even know where to look:

$ man gnome
No manual entry for gnome
$ man gdm
No manual entry for gdm
