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.

Troubleshooting a desktop that does not go into sleep mode/suspend (sh.itjust.works)

Hello all, for a few weeks/months now, my computer has stopped going into suspend mode. Here is what happens when putting it to sleep (using GNOME's power menu) or using systemctl suspend:

Display turns off, peripherals turn off (keyboard lights off etc), fans spin up before sleep as usual
Fans go back to idle speed, computer stays on
Have to press the keyboard, wake the display up and go in the power menu again to suspend it (from the lock screen), and it works every time like this.

I have no idea what could be preventing suspend and what I could find online did not really help a lot. I don't think it is a USB device because I tried unplugging most of them except my mouse or my keyboard and it still did not work, and the second time on the lock screen it always suspends like intended

Distro: Fedora 40
DE: Gnome 46
GPU: NVIDIA GTX 1080Ti (Wayland)
CPU: Intel 10850K
MB: Gigabyte Z590 Gaming X (everything is up to date)

thx !

I simply stopped even trying to use sleep mode because I had some issues and many people responded to my inquiries telling me that it’s always been spotty in Linux. I have one laptop that goes into sleep mode perfectly fine when I close the lid, and wakes perfectly when I open it. That’s an Asus x202e with Pop!OS. Then I have an older HP Elitebook with Elementary OS that goes into sleep mode when I close the lid, but in order to resume, I have to open the lid and then press the power button to wake. And finally my new ASUS zenbook with Kubuntu would go into sleep and never be able to wake no matter what, and required a hardware forced shutdown. So that’s my main system and I simply disabled sleep. When I close the lid it just shuts off the display. It’s actually not bad because I can leave something running and close it, and it continues the tasks.

These days the computers use such less power than they used to, so it’s not really the biggest necessity to use sleep mode.

I mean i could probably leave it on, but it's a desktop, and with the Nvidia GPU using a reported 50W at idle, it would be kind of stupid to leave it on during the night when also using power to run the AC. Also the fans are loud

Yeah not really in the same boat.

TIL: Some people actually like their laptop to wake up after openning the lid!

I've used Elitebooks with elementary for years and found the wakup after pressing a button logical.

What pissed me off about probooks/elitebooks was that they woke up to inform me about the low battery, then went back to sleep due to low battery, then wake up, sleep, wake up, sleep, wake up... and the agony went on until the sweet death. I've never felt so sorry for a non living object before or after.

Oh, and also elementary can't go to sleep from the lockscreen, on any hardware. One of those those bugs that I'm always sure will be taken care of in the next release, but it never is.
