Description Victor Ryzhykh 2026-01-09 14:59:03 UTC
The session is restarted after launching any application.

This problem only occurs with free drivers.
If the disk image contains NVIDIA drivers, the error will not be reproduced.
When running a livecd image of plasma-6.5.80, with the latest updates for today, after logging into a wayland session and trying to launch any application, the session restarts.
I'll attach the output of "journalctl -b 0" taken immediately after the session was restarted.
After starting the session, I launched Konsole and Dolphin to check.
After each attempt to launch the application, the session was restarted.
The x11 session does not have this problem.
I tried to run a live CD image with Neon Unstable on the same computer, and the same error occurs.
I have been observing this behavior on free drivers for a month now.
Until now, I assumed that the error was related to a bug https://bugs.kde.org/show_bug.cgi?id=513003
But the bug https://bugs.kde.org/show_bug.cgi?id=513003 was fixed, but the error with restarting the session remained. :(

I'll attach the output of "journalctl -b 0" taken immediately after the session was restarted.

Thanks for the crash report. As the message at the top of the summary says, if something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl ?

Thanks

Okay, I'll try.
In the meantime, I've created a new journalctl in English.

From the output of "sudo coredumpctl --reverse", I can't figure out what needs to be done next.
I have absolutely no experience with coredumpctl.
There is nothing in the output that indicates a failure.
Comment 5 Victor Ryzhykh 2026-01-09 23:31:08 UTC
I'm trying to boot from this Neon Unstable image. https://mirror.5i.fi/kde-application/neon/images/developer/20250901-0038/neon-unstable-developer-20250901-0038.iso
The system on this livecd image just freezes after booting.
Neither the keyboard nor the mouse respond.
But if I boot on a laptop with hybrid graphics, then everything works fine on the laptop.

After starting the session, I launched Konsole and Dolphin to check.
The output of this log contains information about these applications.

Changed product to kwin because session crashes with "kwin_wayland_wrapper[2381]: KCrash: Application 'kwin_wayland' crashing... crashRecursionCounter = 2"

Release 6.5.90 has been released.
I builded   packages plasma-6.5.90.
Made a livecd image.
There is no longer an error with restarting the session after launching some applications.
I apologize for the false alarm.
