Plasma 6 won't shutdown / logout / etc. with Awesome WM

I am using Plasma with Awesome WM instead of KWin using the configuration suggested here. Ever since the update to Plasma 6 I can't shutdown / logout / reboot / etc. from the Plasma interface. (Running shutdown from terminal works of course, but that is suboptimal.)

Looking at journalctl I noticed:

systemd[898]: dbus-:1.2-org.kde.LogoutPrompt@4.service: Main process exited, code=exited, stat>
systemd[898]: dbus-:1.2-org.kde.LogoutPrompt@4.service: Failed with result 'exit-code'.

Then running dbus-monitor and looking at the logs suggests that the shutdown process is trying to talk to KWin (which obviously fails) and then falls back to resetLogout in ksmserver, which cancels the logout process:

Is this a KDE bug? Or do we have to use KWin in Plasma 6 now?

Related topic on Manjaro forum, same problem but with i3: https://forum.manjaro.org/t/plasma-6-re … /161617/13

Re: Plasma 6 won't shutdown / logout / etc. with Awesome WM

According to this Awesome WM runs on X server but Plasma 6 defaults to Wayland. Perhaps you need to configure your KDE to run on X11.

Re: Plasma 6 won't shutdown / logout / etc. with Awesome WM

Yes, I already have that:

% cat /etc/sddm.conf.d/x11.conf
[General]
DisplayManager=x11

Otherwise WM doesn't even start. In fact that's essentially the only fix I needed to make it run on Plasma 6. The only problem I'm having is this one I described.

Re: Plasma 6 won't shutdown / logout / etc. with Awesome WM

That only configures SDDM, technically there's a distinct "Plasma on X11" session you need to launch. but assuming you're doing that, chances are this is a bug/regression/potentially intentional in KSMServer. Try a KDE bug report.

Re: Plasma 6 won't shutdown / logout / etc. with Awesome WM

Turns out one was already filed here: https://bugs.kde.org/show_bug.cgi?id=487616

(I wonder why Google results are so bad these days.)

Thanks for the help.
