Description nicode25 2022-05-06 20:49:47 UTC

SUMMARY
When unlocking a Wayland session after the monitor goes in deep sleep, plasmashell crashes. I'm using an external monitor with internal laptop screen disabled. I have issues before that look like https://bugs.kde.org/show_bug.cgi?id=447705, so I waited for plasma 5.24.5. It was not crashing before the update.

STEPS TO REPRODUCE
1. Wait for plasma to lock and sleep
2. Wait for monitor to go in deep sleep mode (10-15 minutes for me)
3. Unlock session

OBSERVED RESULT
Plasmashell crashes.

Comment 1 nicode25 2022-05-07 03:44:00 UTC

Sometimes I can't even restart plasmashell. I get this message with exit code 1 but no crash:
The Wayland connection broke. Did the Wayland compositor die?

Comment 2 David Edmundson 2022-05-08 15:51:38 UTC

>Thread 1 "plasmashell" received signal SIGINT, Interrupt.

SIGINT?

It's not a crash, some third party process  is terminating plasmashell.

Comment 3 nicode25 2022-05-08 16:41:27 UTC

(In reply to David Edmundson from comment #2)

Hi, I probably reported the bug at the wrong plasma product/component but this is new with plasma 5.24.5.
I can also reproduce the bug when connecting/disconnecting 2-3 times the external display.

plasmashell and kded5 are not crashing but both get terminated. kwin_wayland still working.
I cannot restart plasmashell nor kded5 and I get this message:
"The Wayland connection broke. Did the Wayland compositor die?"

I don't know what program is causing this issue. I would need some help to find the source of this bug.
I'm using and Intel GPU.

Comment 4 mr.bonhomme 2022-05-08 19:32:56 UTC

Hi, I have the same problem.

Plasmashell 5.24.5 on gentoo. I Think, but not sure, that It happens since 5.24. 
If I try to re-launch with plasmashell --replace, I got the "The Wayland connection broke. Did the Wayland compositor die?" message.
Kwin_wayland is still running fine when this happens, and others applications are still running. I can launch some new applications  if I have a opened konsole too.
