Hey. Starting relatively recently, when I wake from sleep, some windows (mostly the file explorer Gnome Files) are blurry as in the screenshot. Moving the window or passing the cursor over the blurry area often helps, but sometimes I need to close the window and re-open it.
Here are the sections of my various .nix files that look relevant. I'm worried I have a bad video card!
nvidia.modesetting.enable = true;
nvidia.powerManagement.enable = false;
nvidia.open = false;
nvidia.nvidiaSettings = true;
Below is what looks like the relevant part of my restore from suspend from dmesg. Let me know if I can provide anything else helpful!

You are 100% right about thr wiki, and it doesnt help that there's an unofficial wiki that pops up in search results too. And the wiki it especially out of date and confusing for nvidia. Its a known problem, and a bunch of "high level" contributers complain about it in discorse threads all the time.
You linked "nixos-hardware" repo, so you've obviously done your homework. If youre not importing that as a flake, and importing the "common-gpu-nvidia" (or whatever the module is actually exposed as, thats just the pathing) modules, and instead grabbing the values manually, then you also need to grab the ones from here: https://github.com/NixOS/nixos-hardware/blob/master/common/gpu/nvidia/default.nix
Your gpu is too old to be includes in the cuttoff that nvidia did when starting to open source their drivers, but i wouldn't say its too old to be usable or anything.
The wiki is out of date when they say power Management is experimental and unstable, I recommend setting that to true.
I think the main problem is using nouveau drivers, and setting the option provided in the link above should switch that to their closed source drivers. If you make that change, definitely do a rebuild boot instead of switch, and then reboot into the new Gen.
Its so annoying thag theres open (nouveau), open (nvidia - but only newer gpus), and closed (nvidia). There's been a lot of talk about making major changes to the nixos nvidia configuration settings, but there's a lot of conflicting ideas about how to improve them so it hasn't made much progress.
And apologizes for any weird formatting, especially around option names, on my phone.
I appreciate the common tip; I'll add that.
My rebuild switch reboot seems to be working fine, so I'll see what happens...
Thanks for the time to spent trying to help me!
Im glad to hear that! Whenever I have changes for nvidia, I always need to "rebuild boot" and reboot, but that might be because I use "open = true" or because how I have home-manager setup.
No problem! I've been in a similar situation if you couldn't tell lol, I hope the changes work out!
