Wayland window in X11 ( lemmy.ml )

Hello folks! I’ve been having this issue seen in the screenshot. I get this Wayland window and krunner and other things run in there. After a time I even get the login screen inside the wayland window. If I close it I lose krunner, alt-tab, and other keyboard shortcuts.

Not sure how this is happening or how to make it go away. I did try Wayland at one point but it wasn’t quite working out for me and since I reverted back to X11 I get this issue.

If anyone’s wondering, my main issue with Wayland was that it wasn’t setting the DISPLAY and WAYLAND_DISPLAY environment variables for some reason, and this would cause all kinds of software like Steam and Firefox to not even launch. I tried setting them manually but that didn’t go do well either.

Edit: Thank you all! With your help I managed to find and fix it - it was my fault due to a systemd override launching a service after kwin_wayland.

[Unit]
Requires=plasma-kwin_wayland.service
After=plasma-kwin_wayland.service
[Install]
WantedBy=graphical-session.target

That was the issue. Remved the override and everything works!
I even tried Wayland again and now the display variables are defined correctly from the get go and everything works - although this has been on again off again so it might stop working at one point.

I can’t tell you why this is happening, but what is clearly happening is that your apps are being run under a nested kwin_wayland instance. It’s as though you were running kwin_wayland krunner.

My guess is that whatever fix you attempted here caused this, so you’d need to be more specific about what you tried.

Thanks!
I grepped for kwin_wayland in ~/ and found a systemd override that was there to make the emacs daemon launch after plasma-kwin_wayland.service. I guess I had issues with the daemon not starting properly while I was trying to use Wayland. I removed the override and it fixed everything!

Tl:dr: self-caused misconfiguration, but I didn’t find it without your help! Thanks!

Did you happen to try wayland within the past year? It’s gotten remarkably better. I sadly don’t know how to fix your problem, but be aware that Plasma X11 is basically EOL.

highduc OP ,

Yeah I tried Wayland like a few weeks ago and got the undefined variables I mentioned. Without those the vast majority of apps like Firefox, Steam, etc don’t work…
But since you mentioned it I did give it another go just now and it’s up and running fine, the variables are there:

echo $DISPLAY; echo $WAYLAND_DISPLAY
:1
wayland-0
But this has been on again off again so it might stop working at some point. Only time will tell :)

Unrelated to the issue, but related to the last paragraph: have you tried installing XWayland?

highduc OP ,

Yeah it’s installed (and was at the time I was having the issues too). I didn’t know how to troubleshoot to see if it’s actually working as intended.

$ paru -Ss xwayland
