Ok, I actually understand now what your problem is. What you are seeing
there is a mere *warning* by the systemd generator for the display
manager unit that there is no service file for kdm present and that
systemd used different means like a sysvinit LSB script or similar
to start kdm.
root@vs76:~# journalctl --no-pager |grep display-manager
Jan 09 22:39:09 vs76 systemd[1]: Cannot add dependency job for unit
display-manager.service, ignoring: Unit display-manager.service failed
to load: No such file or directory.
root@vs76:~#
And, in fact, when you look at the output of "systemctl status
kdm.service", you see that systemd used the kdm sysvinit script
to start kdm which is indicated by the prefix "LSB:":
root@vs76:~# systemctl status kdm.service

This isn't an error or a serious bug, it's just an information, nothing
else. And to fix it, you can simply drop the attached service file
"kdm.service" into /lib/systemd/system. This is a service file I derived
from the kdm.service provided for kdm in Fedora. I tested it and it
works without any problems and the warning message in the journal
vanishes and "systemctl status kdm.service" lists a native systemd
service:
root@vs76:~# journalctl --no-pager |grep display-manager
root@vs76:~# systemctl status kdm.service

So my initial approach to fix the issue was right, the service
file was just not correct. As a reference, I am attaching the service
files for lightdm and kdm which are shipped with Fedora. Note that the
kdm.service file from Fedora does *not* specify a BusName unlike the
one for lightdm. Adding a BusName would result in systemd
misinterpreting the exec status and leaving the activation state as
"Activating".
I will ask the release team for a possible pre-approval of a patched
kdm package.
Cheers,
Adrian
