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.

@JRepin Am I the only idiot who uses
systemctl hibernatewith a proper swap partition? Works perfect every time I've set it up.You are not the only person. However, even hibernation mode isn't a sure thing anymore.
@drwho Whatcha mean by "not a sure thing"? Is there some issue with specific hardware, or configuration?

@Lem453 Everything on that page refers to configuration problems. Most of them inferring a misunderstanding (or complete disregard) of the requirements that need to be implemented prior to configuring suspend-to-disk in order for it to work properly. Both the gentoo, and arch wikis have very thorough instructions on how to successfully incorporate this feature.
I mean, even then it might not work. I'm wrestling with it right now (Lemur Pro 13 from System76) and from plain old suspend mode the machine still wakes up randomly (it pops up on my monitoring network as active, and can even be SSH'd into when it's supposed to be in lower power mode). Also, suspend-to-disk hibernation only resumes correctly about 13% of the time (I've been keeping stats while debugging it).
