Description Norbert Zentai 2023-06-12 16:58:30 UTC
Application: plasmashell (5.27.5)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-9-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)

-- Information about the crash:
I just logged into Plasma and sent my machine to sleep. After waking it and successfully logging in, plasma has crashed. I am using X11 because under wayland I get all kinds of display corruption after waking the machine and I have to restart plasma.

I am using a nvidia 3080 laptop GPU in a Schenker XMG NEO E21

The reporter is unsure if this crash is reproducible.

I am also using X11 because I get a black screen using Wayland on Debian 12

Comment 3 Mathieu 2023-07-25 13:09:46 UTC
The same with me : when i wake my computer and then unlock my session, plasma crashed.

Sometimes, if i interrupt the timer for the computer to sleep just a second before it get into sleep mode, i get black screen with only a pointer and there is nothing to do unless reboot the computer.

New crash information added by DrKonqi

plasmashell (5.27.7) using Qt 5.15.10

I waked up the PC from sleep mode, the two times I did it, Plasma Shell crashed and closed every Chromium process.

I'm using a Nvidia GPU GTX 1650, I'm unsure if this is reproducible in some way, but I've noticed that it happen too when:

- Randomly a notification loads.
- Randomly when clicking on a panel to open something.
- Randomly when taking a screenshot.
- Randomly when switching between virtual desktops.
