Trying to install plasma : black screen, startx not working

Hello, I am trying to install plasma. I found tutorials, they seem to be all the same every package is installed without problems and I enable sddm but it is not booting and when I boot with command line startx won’t work.

Searching other threads about the same problems I found the suggestion to enable haveged but it didn’t work

Any idea? Thanks

Hello,

Are you installing KDE Plasma into an existing install or you are using the latest ISO we provide?
I see Nvidia on your profile description. Are you booting with proprietary drivers? What Nvidia GPU is in question there?
