fix: regex pattern breaks for `NVRM version: NVIDIA UNIX Open Kernel …

[tom-ainc]

Changes the regex pattern to work with the latest nvidia driver version info (See issue #217 (comment) ).

$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX Open Kernel Module for x86_64  590.48.01  Release Build
                                                                                          ^^^^^^^^^
                                                                                          Broke the regex!

This also fixes it for me (though I have a different driver version):

hydra$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX Open Kernel Module for x86_64  580.105.08  Release Build  (abuild@OBS)  Thu Dec 11 15:49:40 UTC 2025
GCC version:  gcc version 15.2.1 20251006 (SUSE Linux)

I'll put this here to help others: you can actually build your own derivation with a known/hard-coded version. I do this on some of my machines.

Create a flake.nix with this:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-25.11";
    nixgl.url = "github:nix-community/nixGL";
  };

  outputs = { self, nixpkgs, nixgl }:
    let
      system = "x86_64-linux";
      pkgs = import nixpkgs { 
        inherit system; 
        config = {
          allowUnfree = true;
        };
      };

      nixGL_custom = pkgs.callPackage (nixgl.outPath + "/default.nix") {
        nvidiaVersion = "580.105.08";
        nvidiaHash = "sha256-2cboGIZy8+t03QTPpp3VhHn6HQFiyMKMjRdiV2MpNHU=";
      };
    in {
      packages.${system} = {
        nixGLNvidia = nixGL_custom.nixGLNvidia;
        nixVulkanNvidia = nixGL_custom.nixVulkanNvidia;
      };
    };
}

You can get the sha256 hash ahead of time by running:

hydra$ ver="580.105.08"
hydra$ url="https://download.nvidia.com/XFree86/Linux-x86_64/${ver}/NVIDIA-Linux-x86_64-${ver}.run"
hydra$ nix store prefetch-file --hash-type sha256 "$url"
Downloaded 'https://download.nvidia.com/XFree86/Linux-x86_64/580.105.08/NVIDIA-Linux-x86_64-580.105.08.run' to '/nix/store/20y2iywhlzzzvpvh4yscpgm55fv16wjx-NVIDIA-Linux-x86_64-580.105.08.run' (hash 'sha256-2cboGIZy8+t03QTPpp3VhHn6HQFiyMKMjRdiV2MpNHU=').

And to evaluate: nix build .#nixGLNvidia

There may be a better way to do it, but this works for me.
