Everthing works nice after fresh installation. Only one thing bother me .I have to start kdm manually.
DISPLAYMANAGER="kdm" is set in /etc/conf.d/xdm. xdm added in default level.
After reboot kde doesn't start automatically. I have to run
and kdm starts.kdm
Seems, that kdm starts before xdm ( opinions from others forrums ). Howto fix it with SL?
