I’ve been having issues with my PC not waking from sleep, the fan keeps spinning, but the screen stays black, and it won’t respond. I could just keep it on all the time, but it uses a lot of electricity, so I prefer not to.

So far I’ve tried:

  • Using Wayland / X11
  • Secure boot off/on
  • Installing the latest BIOS update
  • Waking with keyboard presses, mouse movement, power button

Some more information:

  • Sleeps works fine on Windows.
  • I’m using an AMD CPU & GPU
  • I’m using OpenSUSE Tumbleweed, and I’m fully up-to-date (version 20240919).
  • I’m using kernel 6.10.9-1-default (64-bit)
  • I have a swap partition with the same size as my memory

    did you try switching to text mode tty console using Ctrl-Alt-F3 or -F4 or -F1 or so? if that works, maybe switching back helps. if switching back doesn’t help, you can at least investigate the logs/journals with text mode.

      Yeah, I’d certainly try to see if it’s a graphical issue or actually locking up.

      You can also try toggling num/caps/scroll lock to see if the keyboard LEDs respond. That’s a core kernel function, so if even that isn’t working, it’s really locked up. (Or just really slow to respond.)

      It didn’t respond to that anymore after entering sleep mode

        I see. You could try and enable Magic SysRq, but honestly I don’t see how that would lead to a permanent fix.

          Thanks for the suggestion, I hadn’t heard of it yet and it seems very useful. However, I might as well just shut it down completely in this scenario if I have to reboot anyway.
