please update the lightdm package to follow the new logic explained in the DisplayManagerRework page:
This requires shipping a systemd unit file in the lightdm package as well as changes to the .spec file.
Please ping us if you need help, or have questions.
Note that this is an accepted F18 feature, we'd be thankful if you could complete this update in time for the F18 release.
I have already started working on this and will finish it tonight.
Ah, oops. Rex just gave me the OK to commit a patch I prepped. It's already commited now, and being built. Sorry for doing this as well!
But would be cool if you could review my changes!
Fixed in git. Thanks for looking into this!
