I have both ubuntu-desktop and kubuntu-destop installed on my laptop. While sddm works perfectly fine during login, if I choose lightdm as the default login screen, after a reboot, I get a black screen.
The black screen goes away if I remove Kubuntu completely and only gnome files are present.
How do I fix this black screen issue?
OS: Ubuntu 15.04 x64 with Unity 7 and Plasma 5
