I currently use Nix and home-manager on top of Arch Linux.

I have the following GPU set-up in my home-manager configuration:

nixpkgs.config.nvidia.acceptLicense = true;
targets.genericLinux = {
  enable = true;
  gpu = {
    enable = true;
    nvidia = {
      enable = true;
      sha256 = "sha256-NiA7iWC35JyKQva6H1hjzeNKBek9KyS3mK8G3YRva4I=";
      version = "595.71.05";
    };
  };
};

This is following advice from https://nix-community.github.io/home-manager/#sec-usage-gpu-nvidia

This had been working fine until a recent nixpkgs input update (i.e. nix flake update). With all nixpkgs after revision 9cadaf6932b7c926e468f777549d57f04a7212da (which works fine) I get the following error:

The version and sha256 values in my configuration are correct for the version of the Nvidia drivers installed in Arch. Also the home-manager nixpkgs input is set to follow my main nixpkgs input in flake.nix. As mentioned, this all works fine until I use a newer revision of nixpkgs.

Any ideas?
