Plasmashell restarting with multiple applications open

Hello everybody,

yesterday and today i had two crashes with the same setup. As such i think it’s a bug and not an anomaly.

The setup consisted of Firefox and Thunderbird open on Virtual Desktop 1, Anki on Desktop 2, Anbox Snap running the App Reaction Flash on Desktop 3, and GIMP on Desktop 4. In the background i had KeepassXC and Nextcloud running. I don’t think i have been running out of Memory, although i can’t say for sure.

The crash looked like this: The Screen freezes and then turns to black. Shortly after that i get thrown back into my normal Desktop 1 but with no programs open, only the ones in Autostart (KeepassXC). No log out and no complete restart of the device.

I would provide my inxi output. Is there anything else like a crash report, and where would i supply it best?

inxi --admin --verbosity=7 --filter --no-host --width

Thank you everybody in advance.

If all bug report is only this description it’s rather worthless – you should also provide logs from this time, for this see man journalctl. You can paste logs here, we decide if this is bug or something else :wink:

Well, maybe you can’t, but I can. :grinning:

:arrow_down:

… And you’re running all that in Plasma, which is not exactly the lightest of all desktop environments.

Thank you very much for your answers. :smiley:

The reason i thought i haven’t been running out was because i casually checked ram capacity with htop after the first crash, and i stayed within 2-3 GB in RAM and 2-3 GB in Swap according to htop. Also i would suspect some laggines when running out of memory, whcoh doesn’t happen, it’s butter smooth and freezes instantly.

Supplied are the last 3 hours of journalctl. I had 1 or 2 crashes since then.

Edit:
Okay, i tried to specify it a bit more. I think one crash happend at Dec 26 15:11 as the log says i started Firefox and Anbox at Dec 26 15:12 which fits to my behaviour.
Maybe this information makes it easier.

I’ve edited your topic title as it was…

…asking about your attempted solution rather than your actual problem.
