Thank you, Gilbert. I found two files
in /root, .Xclients and .Xclients-default
I moved and renamed them. /etc/sysconfig/
desktop already had DESKTOP="KDE". Once
those two root files were removed, startx
got KDE going. As a bonus, in desperation
I had run Xconfigurator before finding the
real problem, and as a result I've got
a virtual screen going! I love virtual screens!
Just the same, I'd rather that none of this
had happened at all.
Again, thanks a lot Gilbert!
