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.

Side note: does anyone enable or use the magic sysreq key anymore?

If you have a system with long-running leaky browser instances, Alt-SysRq-F is a lifesaver. It calls oom_kill, sacrificing one process to save the rest.

Honestly no. Haven't found the need.

I do, and used it today as well. My AMD gpu sometimes when booting fails to set the correct resolution on the 3rd display, and that causes the graphical session to freeze for some reason and I have to force a restart with sysreq and start the graphical session with a weird script that sets a custom res lol.

I use it for fun

And sometimes for testing system survivability

Gotta keep that kernel on its toes.

It may actually be a security hazard since there is a small chance of e.g. OOM killing your lock screen or other such process.

Not on Wayland

Please tell me that needs physical access to work. Now that I think about it - how does sysrq even work with laptop keyboards?
