Hi all, sorry if I post this the wrong place.

I have a laptop running mint with qtile which sometimes freezes. To the point where nothing responds and I need to kill it. I've tried: sudo journalctl But I don't get any information which helps me.

Can anyone help to debug it?

I would look at these things first.

  1. Try another DE, something like XFCE. See if the problem persists. Sometimes swapping compositors or display managers can help too.
  2. Run memtest. Failing memory can definitely cause lock-ups.
  3. Lastly I'd look at graphics drivers. If you're running Nvidia, switch from nouveau to the proprietary driver or vice-versa and see if that helps.

    Great idea. I will try some time with XFCE. One of the challenges is that I don't know how to trigger the crash, and sometimes it can be days, other times multiple times within an hour.
