Bug Description
[ Impact ]
* Switch to lightdm and plasma will not load.
[ Test Plan ]
* With Plasma installed and working, via the terminal install lightdm.
* Select lightdm as the default DM when prompted.
* Reboot to lightdm and try to log in.
* Without fix lightdm will display "failed to start session" and remian at the login screen
* With the fix login works and plasma session loads as expected.
[ Where problems could occur ]
* Plasma workspace which supplies plasmashell has been rebuilt, so testers should do some due diligence to make sure that plasma starts and runs as expected.
When switching the displaymanager from sddm to lightdm, login fails due to misconfigured lightdm configuration file.

Hello, thanks for reporting this, but in order to properly triage this, I need more information.
How exactly did you install LightDM? Did you remove SDDM after installing LightDM?
And most importantly, is this still an issue for you?
This looks awfully similar to a bug I've seen before, so for now I'm marking as Incomplete, but if this still affects you, please change it back to New.
Thanks for making Kubuntu better! :)
