2004-02-06 Fedora Tips 37:
This is a followup to Fedora Tips 1.
If you use kde in fedora, you lose the ability to shutdown/reboot the computer without fist logging out and then shutting down from the gdm displaymanager. To change displaymanagers add the following to /etc/sysconfig/desktop
or simply type
bash# echo 'DESKTOP="KDE"'> /etc/sysconfig/desktop && echo
'DISPLAYMANAGER="KDE"' >> /etc/sysconfig/desktop
