I’m having hard time finding setting for my display.
When I press Meta+P nothing happens.
Can you get to them via the right-click context menu on the desktop, or from the systray icon for it (probably hidden)?
I don’t know why the shortcut isn’t working for you.
Here’s the right-click options on my desktop
That is odd, as kscreen is a defualt part of Plasma, and neon includes it.
Still, I am glad you found what was missing.!
