New changes. Please read my last post
I'm having a really weird problem. I just updated my Debian Stretch to Buster (testing) few days ago. Everything went fine in the upgrade, and everything seems to work in the new system. However, I'm getting random logouts occasionally. The system automatically logs me out. when I log back in, my work is gone (so it is really logout rather than lock). But still it looks like the session stays open, because when I reboot, I get a message like "a stop job is running for user auvo Session 1/2/3..6" depending on how many logouts have happened before that.
Seems like it is somehow related to Google Chrome/Chromium. Because those logouts happen (or at least have happened so far) only when I'm browsing Internet via Chrome/Chromium. And I can for example watch Netflix for hours via Chrome without a logout. And use any other desktop app, like Spotify for example, for hours without a logout. But if I just surf around, I may have a logout in a minute. Sometimes longer, but in five minutes every time, I'd say. Today I installed Firefox, but haven't enough time to test it. But I didn't get any logouts on that 15 minute testing.
I haven't tried to reinstall Chrome and Chromiun yet, but that's probably what I should do next. It just feels very odd that it logs out, instead of crashing the application or so. And because it happens both to Chrome and Chromium (which do are basically the same), it is hard to believe at really depends on those apps. I have checked dmesg and Xorg.0.log, and haven't found anything too critical from there. Also tried googling, but haven't found anything very fresh, and nothing really Debian-related. Do you have any clues, from where to start seeking for the problem? I'll post the logs here when I get back home.
