From the messages on the various bug reports, and from the discussion I had with Aaron and BluesKaj in #kubuntu-devel, the common pattern seems to be:

Loaded: loaded (/lib/systemd/system/sddm.service; disabled; vendor preset: enabled)

from systemctl status sddm. A simple "systemctl enable sddm" should fix that. I'm clueless what disables sddm in the first place though...
