From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Laptop randomly freezes. How to debug it? (feddit.dk)

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.

Try another DE, something like XFCE. See if the problem persists. Sometimes swapping compositors or display managers can help too.
Run memtest. Failing memory can definitely cause lock-ups.
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.

Boot memtest

Leave it to do it's thing overnight. That will at least check for badly failing RAM.

I've run this on machines that I thought were ok, only to find... they weren't.
