Well, random guess of the day: lightdm was not installed during the upgrade because kubuntu-desktop was not present (thus no dependency tie to lightm) and kdm was removed in the post-upgrade cleanup either because there were no dependency chains to in anymore or there is special magic that marked kdm for removal (probably latter I am guessing).
