Bug Description
After installing kubuntu-desktop meta package I saw a prompt telling me that both sddm and lightdm are available and I am forced to choose one between them.so I chose lightdm.on the next reboot I was unable to use GUI.
After 2-3 weeks,I retried using sudo dpkg-reconfigure lightdm and selected lightdm.still fails to run GUI.
sddm works fine and is able to handle both Plasma and Unity.

Your lightdm,.log shows that you are failing to authenticate:
[+83.70s] DEBUG: Session pid=1546: Authentication complete with return value 7: Authentication failure
So it appears that something in PAM is failing (or you are typing the wrong password!)
