KDE desktop configuration?

1. #yum groupinstall "KDE Desktop" #yum install "switchdesk-gui"

2. in /etc/sysconfig/desktop
 DESKTOP="KDE"
 DISPLAYMANAGER="KDE"

DESKTOP="KDE"
DISPLAYMANAGER="KDM"

 3. $ cat ~/.dmrc
 [Desktop]
Session=kde
 Language=en_US.utf8
 Layout=us

If there is no .dmrc file in the user's home directory, the setting from /etc/sysconfig/desktop is used as a default.
