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?

Can you ctl+alt+4 to another terminal? Could you ssh from another machine?

    No, I can't access another tty during a freeze, unfortunately.

    That's may be a hint!

    The only times I've had the desktop freeze on Linux and the alternate terminals fail to respond, I had a hardware issue.

    In one case, I was on a Raspberry Pi, and my power supply was not delivering clean enough power for the board.

    In another case, my fan wasn't connected properly and the motherboard was overheating.

    Edit: Oh! I think I had this behavior once with a RAM stick that was terribly subtly not quite all the way in the slot.
