It started freezing maybe a month or two ago. It happens anytime between a few seconds after the OS loads, to hours or days later. I do not recall downloading anything around when this issue began that could be suspect.
I’ve put off fixing this because I have no idea how to even begin troubleshooting it. Internet searches for “Linux freezes” returns practically countless potential problems.
What are some recommendations? I have my root directory on a 30 GB partition separate from my home directory, which I think makes reinstalling my base image (Debian) easy without losing personal data, so that’s an option. Maybe there’s a system log file that would provide some insight?
I’m Linux dumb so please teach me how to fish!
I’ll add that my Windows install (on a separate drive) doesn’t freeze, and my Linux install is on a new Samsung drive that didn’t report issues, so the problems unlikely hardware related.
02:05 18OCT: Thanks for all the quick responses, a lot of helpful suggestions so far. I should clarify that “my computer freezes” means it is 100% unresponsive until it is rebooted. Ctrl+alt+del spam or changing terminal sessions when its frozen does not get a response. The last few entries in my most recent journalctl boot outputs are different from one another, and the I did not see any errors. For now, I’ll boot a live USB and let it sit for while, see if it crashes again.
If it’s freezing regularly, you could try booting a live usb of any Linux distro and see if it does the same thing. That will tell you relatively quickly if it’s a hardware problem or a software problem.
I mean, potentially not that quickly if they have to wait days for it to happen. Good low-investment-of-personal-time-and-effort suggestion though.
Yeah, I would give it a few hours to most of the day to test and then move on with something else. I really recommend journalctl though. Of course it depends on how long it stays on and how fast you can read the logs.
