I did exactly that, as I have been bitten by that bug, too. The problematic line in my setup is > greeter-session=lightdm-kde-greeter If it is active, lightdm fails to start, if it is commented, lightdm works. In the package's current config file, this line does not exist. As Fabio Rosciano has the line > greeter-session=lightdm-greeter in his config, too, this is very likely the culprit. The next line > greeter-hide-users=false is at the same place and active both in our conf files. Thus I think these lines have been created automatically, shipped by an older version or came from some tutorial. Therefore it's important, that lightdm can cope with this line without crashing, as this will hit more users and some users won't have the skill needed to remove a line in a config file when upgrading to Jessie.
