I started run-level 5, logged in as root everything was fine, I got up kde. Tried to log in as myself, then X crashed. Tried with another user that also crashed X. I changed to xdm by putting AnotherLevel into /etc/sysconfig/desktop Then I was able to log in as myself and I got the kde window system. I am using AfterStep, so I wanted to continue with that. Even if I have a .wm_style file with AfterStep it did not start AfterStep. I was able to start AfterStep by removing almost everything in Xsession and adding 'exec Afterstep'
fixed in the latest kdebase packages...it was a pam problem with kdm.
