On and off for a couple of months I’ve had a strange issue with GNOME; it will (apparently randomly) log me out perhaps once per day.
Here’s a Reddit thread where someone else experienced it: Reddit - Dive into anything
I’ve not been able to find any other examples of exactly the same behaviour.
The system is Fedora 40 (Silverblue) with AMD CPU and GPU. Another laptop I have with an Intel CPU and Nvidia GPU isn’t affected (I don’t know if CPU/GPU is relevant, though).
I’m not sure how to investigate this - is there anything in particular I should look for?
Do you have any crashes in coredumpctl?
I found this:

That last one is approximately the same time as one of these logouts.
Well a Signal crash is probably not relevant. I was hoping GNOME itself would be crashing, but it’s not. Exiting without any crash is going to be much harder to debug unfortunately.
Thanks - I feared that might be the case.
Unfortunately, I have so far been unable to spot anything which appears to be related to these crashes.
