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

Do you have a swap partition? If not try disabling hibernation.

Yes, I do have a swap partition with the same size as my RAM

Had that happen yesterday for the first time with a similar (AMD CPU and GPU) setup.

Have you been able to find a fix?

[–] [email protected] 2 points 1 month ago

Okay, it now seems to happen more frequently.

Man, I had so many issues related to standby and VRR seemingly caused by the amdgpu driver most of the time that I'll definitely reevaluate whether an AMD GPU is the correct choice for Linux in the future.

Didn't happen again so far, so I didn't investigate further. The qcode display on my mainboard displayed an error code I think.

I've been having similar issues for a while on OpenSUSE.

I noticed that if I press the power button it works, but if I try the keyboard, the issue happens

[–] [email protected] 1 points 1 month ago (1 children)

I can't wake it with the power button either. Do you mean that it freezes after using the keyboard?

[–] [email protected] 2 points 1 month ago

Yes, that's what I meant.

Sorry I can't help you more

[–] [email protected] 2 points 1 month ago (1 children)

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.

[–] [email protected] 2 points 1 month ago (1 children)

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

[–] [email protected] 2 points 1 month ago (1 children)

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.
