Description Orlando Rodriguez 2022-02-23 13:32:54 UTC
Application: plasmashell (5.24.2)

Qt Version: 5.15.2
Frameworks Version: 5.91.0
Operating System: Linux 5.13.0-22-generic x86_64
Windowing System: Wayland
Distribution: Ubuntu 21.10
DrKonqi: 5.24.2 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Just login to the pc.

- Unusual behavior I noticed:
The splash appears, after that I can see the wallpaper but no panels are loaded. After some seconds the crash modal appears and the wallpaper dissapears. Just a black screen.

- Custom settings of the application:
I am using some widgets like inline battery, configurable button widget and Toggle Panel button widget.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted

Are you using fish shell?
Comment 2 Orlando Rodriguez 2022-02-24 03:03:46 UTC
No, I am not using Fish Shell.
Comment 3 Nate Graham 2022-02-28 21:49:00 UTC
Thanks. Can't tell from the backtrace what might be happening. Hopefully someone more senior can take over.
Comment 4 Orlando Rodriguez 2022-02-28 22:06:03 UTC
Thank you so much for your answer Nate, I'll keep updating every version and testing this. Maybe I'll try a clean install too.

Comment 6 Orlando Rodriguez 2022-04-26 03:13:52 UTC
After upgrading my distro(kubuntu) to 22.04, the issue is gone for my laptop with AMD iGpu. My desktop with Nvidia is not working yet, however, that's in some way expected.
Comment 7 HFarmer 2022-05-01 13:39:42 UTC
The crash reporting assistant treats a bug I have which is complimentary to this one as a duplicate.   This was a person for whom Kubuntu Wayland was not working in 21.10 but the upgrade to 22.04 fixed it.  

I had Wayland working fine in 21.10 but the upgrade in place to 22.04 broke it.   There was an anomaly during my upgrade process which I had to restart, but after that everything else on the system worked fine.  Everything works under X11.  I am even running this program under Wayland because I know how to get to a shell and to launch programs from it.  Just like using X11 without a window manager in the 1990's.  However, this is unacceptable for a modern desktop in the 2020's!   We must not be cavalier about these problems.  

The original problem should not have existed for Orlando Rodriguez under 21.10 and my working Wayland should not have been broken by an update in place.  NO, a total clean wipe of my system drive at this point is not desirable as in every other way this system works like a well tuned beast.  Finally.

Hmm, I wonder if Plasma crashed because KWin crashed. do you see any "kwin_wayland" crashes in the output of `coredumpctl --reverse`?

New crash information added by DrKonqi

plasmashell (5.24.4) using Qt 5.15.3

- What I was doing when the application crashed:
This bug was created after upgrade my OS from Ubuntu Studio 21.10 to Ubuntu Studio 22.04. Plasma works on X11, but crash when login with Wayland, so I could not do anything but seeing error message.

I have not noticed that.  I can try.  That said if Kwin crashed then, under X11 that used to mean no ability to manage windows.  No resize, close, move etc.  I can do all of that but I know Wayland works differently.

Kwin is not crashing Plasmashell is. In fact other key parts are also crashing.  If I ctrl-alt-del to log out of this "session" the logout greeter also fails.  All of these same programs (?) work in X11.  They previously worked under 21.10 for Wayland.
Comment 13 Nate Graham 2022-05-05 21:21:18 UTC
OK, thanks.
Comment 14 HFarmer 2022-05-26 04:47:27 UTC
I'd like to point out that exactly once I was able to login to plasma wayland BUT for some reason my sound didn't work.  Like devices were not detected.  No idea if this was a coincidence.

Comment 16 galder 2022-06-18 10:59:45 UTC
Same problem here.
I just update today my old laptop. Just to test new Kubuntu 22.04. 5.24.4
After a fresh instal,l Plasma x11 is fine but Wayland crashes.

I updated also to latest Kubuntu backports plasma 5.24.5
Same problem. 
I only see my mouse cursor and a black background.
If try to run plasma-shell --replace, it crashes.
The GPU is Nvidia.

For now, no way to use Wayland in Kubuntu 22.04

Comment 19 galder 2022-07-24 12:37:49 UTC
Just to add some findings. for me Wayland crashes in 5.24.6, however it does work in 5.25.3. 
My system is based in Ubuntu 21.10 with Nvidia drivers.
Regards.
Comment 20 David Edmundson 2023-01-03 11:41:13 UTC
These logs show that kwin quit. We have no backtraces of kwin to proceed.

If we get traces on that, lets open them as new kwin bug reports.
