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.

    this is important, and will help you find solutions much more specific than just “system freeze”

    • Right after a crash, once you reboot, run journalctl -b -1 and scroll to the bottom. Look for any big red text, all of that will be very helpful to diagnose this issue

    Otherwise,

    • Does it freeze permanently, requiring a reboot, or for a few seconds?
      • If it’s just for a few seconds, and you’re on an AMD system, it would sound like an fTPM stutter. A BIOS update would likely fix that, it was a widespread issue.
    • Are you using an AMD or NVIDIA GPU?
    • Do you play any games or use any software that uses OpenGL? (Blender and minecraft are some I’ve had problems in before)

      No red text from journalctl unfortunately. My last few sessions each end with different messages too. One is a KDE Connect warning, a few others echoing some commands I sent in the terminal, etc. No red errors.

      The system freezes permanently, requiring a reboot.

      I have an AMD GPU, and likely have OpenGL installed.
