SUMMARY

After resume, I have to always set switch to external screen since I always disable my laptop screen. In X11, I don't have to do this.

STEPS TO REPRODUCE
1. Ctrl+P, switch to external screen
2. Sleep-Resume / Restart
3. KDE resets to show stuff on both screens

Did you set the Ctrl-p shortcut yourself? It's not set by default in KDE. I haven't got this issue on my laptop

You can try removing the configuration at .local/share/kscreen/* to reset it. See if you can reproduce it again after that.

Yeah, after I removed those it works. Also, most likely I am going to ditch wayland since it keep crashing the wayland session randomly for a few times.

Thanks.
