Hello everyone,

I have an issue with my desktop, which I really don’t understand.

It is a desktop PC, with a Nvidia GPU, which I use for development (of AI, but like the image analysis part, not the slop part). I usually let it always run, and my previous machine was working fine like this.

However, on this machine, I get crashes after either a few days or a few weeks.

These “crashes” are weird : the machine is still up (and I can ping it), however I can’t ssh into it, I can’t connect to cockpit either, and can’t login physically on it (the display is frozen).

The only way to get it back up is to forcefully shut it down, wait a little and then powr it back up; but this isn’t ideal, since it interrupts computations etc

The only crashes shown in journalctl are related to irrelevant (I believe) programs : KDEConnect, DrKronqi, etc; nothing right before the crash.

Do you have any idea what could cause this ?

I tried logging temperatures, but nothing abnormal showed up. I ran memtest86+, nothing showed up either. Smart tells me everything is alright for my drives as well.

Right now I’m thinking about changing the alimentation or the motherboard, but frankly I don’t know what’s going on and it’s really puzzling me.

    Sounds like a long tedious elimination process is ahead.
    But since the only errors you get regard KDE, I’d try installing another desktop environment. Afterwards you can generally choose which desktop to log into at the login screen. And when it’s resolved whether or not KDE is the problem, you can easily switch back if you want. So it’s very easy to try.
    But each elimination will take 5 days!! If the computer behaves the same each time it crashes, it is definitely NOT random. If it was random it would be different things each time, and then it could be RAM or even CPU problems. But this sounds like a software problem.

    I’ve had similar issues when I ran out of system memory. It also didn’t leave any traces in the journaling program, but I think it did say something about it in dmesg. Not sure though. But since you’re probably using the VRAM and not the RAM, maybe this isn’t it at all? Just spitballing.

    I had a similar issue on bazzite and I think it had to do with the Out Of Memory service. This link might help if that’s it.

    Disclaimer* if you look at my account I have mentioned that I only joined linux this year and have only distro hopped once so beyond this post I can’t really offer much assistance.
