Sounds like a bug of some description. The nixpkgs package for nvidia is perpetually a lil’ behind, because stability guarantees. Maybe give manually updating a shot, at least until the next NixOS release:
hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.mkDriver {
version = "580.76.05";
# Update these hashes to whatever nix tells you to,
# and set them back to `lib.fakeHash` every time you
# change the version.
sha256_64bit = lib.fakeHash;
openSha256 = lib.fakeHash;
settingsSha256 = lib.fakeHash;
# You can leave these unspecified
sha256_aarch64 = lib.fakeHash;
persistencedSha256 = lib.fakeHash;
};
will checkout this solution in next couple of days and get back to the thread if the issue seems to be fixed - thank you in advance @TLATER for the suggestion
