Is there any information on how to get proper screen resolutions to show up?
In X11 everything works just fine, however in wayland I get this:

I note there are little information icons next to the resolution (i inside a small circle).  Does clicking on those relate anything useful?

You shouldn't see an X11 screen here... Do you have QT_QPA_PLATFORM=xcb exported globally somewhere? qt5-wayland installed?

@ewaller - no nothing useful

@V1del:
Yes qt5-wayland installed.
I start with this script, using xcb fails to start plasma, it's just loading...

using startx
```bash
~/.xinitrc
#!/usr/bin/env bash

export DESKTOP_SESSION=plasma
export XDG_SESSION_TYPE=wayland

if [[ "${XDG_SESSION_TYPE}" = "wayland" ]]; then
  export QT_QPA_PLATFORM="wayland;xcb"
  export CLUTTER_BACKEND="wayland"
  export SDL_VIDEODRIVER="wayland"
  export GDK_BACKEND=x11="wayland"
  export MOZ_ENABLE_WAYLAND=1
  startplasma-wayland
else
  startplasma-x11
fi

```

@V1del: I tried to do only:
startplasma-wayland

not using startx, this worked perfectly thanks both of you.

Some more information on why that works: You should never use startx to start a wayland session. startx will start up an x server and then the desktop environment inside that. For wayland, you start the desktop environment directly, it will not use an external display server, but provide its own server/compositor.
