ROSA Forum

I was use Rosa Fresh R6 64 bit, and I want to try Plasma Desktop 5, after I install LXDE desktop and login there and install KDE 5 with task-plasma5 but when the installation continue suddenly black screen comes and lxde session logging off, I thing KDM was deleted now there is no login screen which is KDM Screen.

Now I want to repair my system and install Plasma 5 login screen and Desktop Environment, how can I do it in black screen which is comes when pressing ctrl-alt-f2 after boot screen?

Also in the black screen these words write

[drm:radeon_init] *ERROR* no UMS support in radeon module!

I search on internet but I culdn't find working solution

Have you tried installing sddm? I think sddm replaces kdm in plasma 5

task-plasma5 removes kdm and installs sddm. But sddm service is not enabled by default. So you should login as root and enable it:

In order to prevent broken systems, is it recommended from my side to test ROSAs implementation of plasma 5 with a live ISO:

PLEASE CHECK the "Status" column and use of course just successful builds. And check the MD5/SHA number.
