Chiming in simply to say you’re not alone, I’ve had similar issues with a different piece of hardware (Thinkpad T15g Gen 2 – 11800h + RTX 3080 mobile). It also sounds like a similar issue to the suspend/resume issues @wendell had with the Razer Blade 18 during the review a few months ago? Though I didn’t see the suspend/resume issues mentioned in the related thread (Razer Blade 18 - Linux Setup Notes and Review), just an oblique mention in the Level1Linux review video for that one - https://youtu.be/WJBk1_T3gyw, around 4:04 - 5:20 in the video.
So far as I’ve been able to find, it’s a nVidia driver issue, but I could well be wrong. Arch wiki had a few suggestions - NVIDIA/Tips and tricks - ArchWiki - but those were already implemented by default in the distro I was using at the time, and it still happened. Hoping to be wrong though, and there’s something I’m missing that’s just beyond my current experience level.
