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?

There are an absurd amount of this:

That seems to be there all the time, and also before crashing/freezing

If your machine is a Tuxedo laptop, this thread might interest you. Seems as though this user was hitting thermal limits and their laptop would freeze/poweroff to keep from dying.

+1 to this line on inquiry.

When I've managed to get a modern Linux desktop to freeze, I've had a bad power supply, or heat issues, each time.

Interesting that the power supply might be the problem. Never thought about that. Sounds like a nightmare to come to that conclusion.
