@60ead002 oh, I was recently looking into how to enable this for NVIDIA drivers. I guess AMD does it by default! I think my suspend issues are just caused by bad NVIDIA drivers though and I should really go AMD next time..

 @d38bae73 interesting. Seems like the default Nvidia behaviour is more likely to successfully suspend.
