This is maybe a small problem, but I’ve been trying to install KDE Plasma as my DE. It’s just a matter of personal taste, nothing related to any project needs. I’m installing like I would in any Ubuntu install that came with another DE:
sudo apt install kubuntu-desktop
Set sddm
instead of gdm3
. Then I had issues with black screen on sddm
. I tried to set gdm3 back and login into Plasma. The result was always an OpenGL2 error. I then added sddm
user to video
group. Now sddm works fine.
My problem now is Plasma itself, which stays black with the mouse moving. Supposedly were the shortcuts to Chromium and the forums are, I am able to right click and open them. But that’s about it. I tried ssh -X
to open systemsettings5
from my other Linux machine and got this:
Application: System Settings (systemsettings5), signal: Aborted
