Kdm fails with systemd

Question

Hello, i recently started using systemd and followed the instructions given in the wiki.  The problem is that systemd drops me on a terminal instead of starting kde.  I was wondering if anyone knew how to fix this problem?
Right now I have to stop the systemd service from running ad start kdm as root to get into kde.
I have of course used the command
systemctl enable kdm.service
journalctl shows me this error
kdm[297]: X server died during startup
kdm[297]: X server for display :0 cannot be started, session disabled
Any help on this problem would be greatly appreciated.  Thank you.

Thank you for your reply.  I found nothing interesting in xsession-errors, except for errors about inotify.  I however found this in my Xorg.0.log

[ 137.665] [mi] These backtraces from mieqEnqueue may point to a culprit higher up the stack.
[ 137.665] [mi] mieq is *NOT* the cause. It is a victim.
[ 137.737] [mi] Increasing EQ size to 512 to prevent dropped events.
[ 137.737] [mi] EQ processing has resumed after 15 dropped events.
[ 137.737] [mi] This may be caused my a misbehaving driver monopolizing the server's resources.
I have no idea what is happening here.  I have the latest nvidia driver from core.
