Where are the screen resolution settings? I started the KDE system settings and see this:

screen1 screen2

Are there somewhere else? Where?

Or is something broken? Maybe some missing permissions?

Yes, something is wrong. This window is supposed to host at least two tabs, and resolution settings are on another tab.
This will show you what KCM modules are present.

kcmshell4 hardware --list

The one called kcm_kscreen must be present. May be you should reinstall kscreen package

sudo apt-get install --reinstall kscreen

  • Maybe a restart of the display manager or a reboot works already. – moooeeeep Aug 24 '17 at 11:43
  • May be. It was written 3 years ago, and, I think I had KDE4 in mind. Control Panel had been reworked since then. Anyway, I ditched KDE in favor of Cinnamon. – Barafu Albino Aug 24 '17 at 11:47
