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.

Help getting Ubuntu with KDE to sleep (lemm.ee)

submitted 8 months ago by [email protected] to c/[email protected]

My PC is running Ubuntu 22.04, with KDE Plasma 5.24. When I select Sleep from the Application Launcher, it always starts t go to sleep, but then it seems like a 50-50 chance that it will stay asleep. Many times, it wakes right back up again within 10 seconds. If I try to make it sleep two or more times, sometimes it will eventually sleep but not always.

I've done some searching and cannot find a resolution to this.

It seems I'm not the only one too - https://superuser.com/questions/1795451/kde-plasma-does-not-sleep

Is there a sure-fire way to tell Ubuntu KDE to sleep?
If not, what are some things which might wake it up again?

Thanks!

Make sure power management is properly configured on the Nvidia card.

I had this exact issue on an MSI motherboard. What ended up being the fix for me was changing the “Wake Up Event By” toggle in my UEFI. It was set to “BIOS”. Changing it to “OS” immediately fixed all the issues I was having with suspend

Of course. I troubleshot a similar issue for a while. Finally found the toggle in BIOS and felt a bit dumb
