[RndTbl] Lost KDE

[author]

I made a big mistake in Red Hat 7.1 KDE.
Just to see what it looked like, I chose
Twm as the window manager. Primative or
what! Nothing there! And I can't get KDE
back! I've messed with /root/.Xclients.default
and /etc/sysconfig/desktop but nothing good
happens. In Slackware all I'd have to do would
be run xwmconfig on the command line, but
Red Hat has its own unique ways that I do not
understand. Can anyone tell me how to get
KDE back?
