Advice needed. PC not waking from sleep with OpenSUSE TW (lemmy.world)

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

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.)
