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:

  1. Display turns off, peripherals turn off (keyboard lights off etc), fans spin up before sleep as usual
  2. Fans go back to idle speed, computer stays on
  3. 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 !

Perhaps not useful, but my linux machine doesn't sleep unless I disconnect my ploopy trackball first, exhibiting the same symptoms.

I had this theory since I got some new usb periphs relatuvelu recently, but that was not the issue
