As per https://bugzilla.redhat.com/show_bug.cgi?id=850775 , all DMs need to ship systemd presets in F18+ to ensure they get enabled post-install. Filing this bug so it can be nominated as NTH to get the fixed lxdm into the Alpha.
Discussed at 2012-09-10 QA meeting, acting as an NTH review meeting. Accepted as NTH as it's a blocker for a non-blocking desktop.

LXDE live is working but not "yum install lxdm", so moving back to assigned. * Fri Sep 07 2012 Adam Williamson <awilliam> - 0.4.1-4 - ship a systemd preset for lxdm (#855470) - add After: livesys-late.service to the service file, testing of other DMs indicated this is needed for lives According to Lennart in bug 850775, preset should not be relative to livesys-late.
OK. That should be filed separately though. It's not this bug. Nor is the 'yum' case. I'm not sure that's actually intended to work as you think it is. You'd best check with Lennart whether you should file it as a bug or whether it's intended. But it's not this bug.
lxdm-0.4.1-4.fc18 has been pushed to the Fedora 18 stable repository. If problems still persist, please make note of it in this bug report.
