My /etc/conf.d/xdm has DISPLAYMANAGER="kdm-3.5" kdm starts correctly always. The problem comes when I log out, kdm crashes and I have to log in the text console and restart the xdm service. This is the message I get in /var/log/xdm.log: xdm error (pid 2791): Display :0 is being disabled (EE) SIS(0): Unable to map IO aperture.

That seems to be an issue with your graphics driver or X server. I don't see how we can fix that ...
