Qt: Session management error: None of the authentication protocols specified are

[orinoco]

Hello,

Since the last D-U (yesterday) I see the following error with journalctl.

Qt: Session management error: None of the authentication protocols specified are supported

Various services report the error e.g.

plasmashell[27624]: Qt: Session management error: None of the...
kmix
latte-dock
yakuake
and more

Apparently all services that have to do with KDE/Plasma.

I can't see any other malfunctions at the moment either.

Are there any reasons for this? Has something changed in QT/KDE?

I see the same since yesterday, noticed today it appears in X11 sesssion and gone/hidden in wayland session.

Same here KDE/Plasma with x11. Another system with KDE/Plasma and Wayland seems to be okay.

First I saw this here

$ kioclient move myfile.txt trash:/

If you want to test for your own. It's a simple command to move a file/folder to the trashcan from console.

This log entry also appears on my system and I did not notice it at first.
But my X11 session management behaviour has changed.
The "On last logout" option, described in
https://docs.kde.org/stable5/en/plasma-desktop/kcontrol/kcmsmserver/index.html
no longer worked.
Plasma™ no longer restored my session at the next login,
Is there another user who has experienced the same?

Das Verhalten ist etwas unberechenbar geworden. Unter KDE/Plasma X11 wurde Firefox mit mehreren Fenstern korrekt wieder hergestellt. Konsole, LibreOffice und Okular dagegen nicht. Und KiCad wurde zwar wieder gestartet, aber auf der falschen Arbeitsfläche.

The behavior has become somewhat unpredictable. Under KDE/Plasma X11, Firefox was restored correctly with multiple windows. Konsole, LibreOffice and Okular, however, did not. And KiCad was started again, but on the wrong desktop.

Firefox was restored correctly with multiple windows. Konsole, LibreOffice and Okular, however, did not.

I have not been able to verify a single programme that has been correctly restored.

Ich habe noch noch kein einziges Programm gefuden,das, das korrekt wiederhergestellt wurde.

I have not been able to verify a single programme that has been correctly restored.

Only one that is remebered is the gkrellm window, but that is set in the setup of gkrellm.
