Unfortunately the newest KDE neon trips over it's own feet and cannot set up printing:

(This has nothing to do with the question, but is the reason why I need to run KDE as root; it seems as if Manjaro-users have the same problems as KDE-neon users)

I have set up root with a password and can log in on the command line just fine, but when I try to log into KDE it just fails with "login failed".

Since this can be useful for other situations as well, I would like to know:

How can I log into KDE as root?

    Just use the cups web interface. localhost:631 in your browser. – jordanm Sep 1 '19 at 19:37
  • Using cups is probably a cleaner way to setup a printer. Having said that, you could open a tty with Ctrl+Alt+F2, login as root there, and issue startkde. Or just run the KDE printer program as root. – Lorenz Leitner Sep 1 '19 at 19:39
