Plasma 6.1.4 shutdown hangs at plasma-fallback-session

[ese002]

I have long had my system set to restore a manually saved session at startup.

With the upgrade to Plasma 6.1.4, this doesn't work. Shutdown and logout exit PlasmaShell and then it just hangs. All application windows remain. I have tried closing all the windows but this has no effect. What does work is to kill plasma-fallback-session-save. Shutdown/logout proceeds normally from there, though presumably skipping whatever plasma-fallback-session-save was doing.

I tried switching to "restore apps on last logout". That seemed to work once. But then I switched back to "When session was manually saved". It hung on plasma-fallback-session-save. On the next boot, I tried switching to "restore apps on last logout" and logging out. This time logout and shutdown did nothing. No plasma-fallback-session-save either. Switching again to "When session was manually saved" gave me the usual hung plasma-fallback-session-save.

Throughout all this, "switch user" works fine.

Any idea how to restore logout/shutdown function?

That's with X11 session handling, right? Just to be sure.

Please also try with a clean testuser profile. This has helped in the Gentoo bug.

You should put the patch in /etc/portage/patches for testing.

I have further found that if I switch first to "empty session" with a logout in between, I can switch from "last saved" to a working "on last logout". Switching from "last saved" to "last logout" causes the usual hang and the resulting "last logout" session also hangs at logout.

[ese002]

Correction. A clean test user does not work. It only works for "last logout" and "empty session". "last saved" still hangs.

Thanks. It would be best to convey these findings to upstream, it really does not make sense for me to relay all user reports.

The next best thing would be to do as https://bugs.gentoo.org/938925#c1 which is not a fix, but a workaround (and yet another confirmation this was a problematic fix).

Please test with kde-plasma/plasma-workspace-6.1.5-r2. It contains the fix for upstream bug https://bugs.kde.org/show_bug.cgi?id=488853

No, that's a different issue and a separate thread would be much better for you to possibly get some help (for any chance to get started though you'd have to provide much more information).

With 6.1.5-r2 this specific problem seems to be solved. However, it exposes another problem. After I save a session, the logout and power off buttons no longer do anything. Switching to "clean session", a workaround for an earlier version of this sort of problem, doesn't help. If I force a shutdown with "systemctl poweroff", the system seems to behave properly on the next boot. I haven't done enough testing yet to be sure that the save actually worked or if I am getting an old session.

[ese002]

Ok. Confirmed. Saving the current session does work. Actually logging out or shutdown after doing that requires killing start-plasma but the new saved session will be used at next login and logout and shutdown will work from that session.
