Advice on Improving my Nvidia.nix file?

Help
1

I am using NixOS with plasma 6 running Wayland. I am getting a lot of issues with games and Electron apps not working at all.

This is my current Nvidia.nix file that I’m importing.

{ config, lib, pkgs, ... }:

{

  options = {
    # Define any custom options here if needed.
  };

  config = {
    boot.kernelParams = [ "nvidia_drm.fbdev=1" "nvidia-drm.modeset=1" "module_blacklist=i915" ];

    hardware.opengl = {
      enable = true;
      driSupport = true;
      driSupport32Bit = true;
    };

    environment.systemPackages = with pkgs; [
      libva-utils
      vdpauinfo
      vulkan-tools
      vulkan-validation-layers
      libvdpau-va-gl
      egl-wayland
      wgpu-utils
      mesa
      libglvnd
      nvtop
      nvitop
      libGL
    ];

    services.xserver.videoDrivers = [ "nvidia" ];

    hardware.nvidia = {
      forceFullCompositionPipeline = true;
      modesetting.enable = true;
      powerManagement.enable = true;
      powerManagement.finegrained = false;
      open = false;
      nvidiaSettings = true;
      package = config.boot.kernelPackages.nvidiaPackages.production;
    };
  };
}

Any advice?

There are some known issues running Electron based apps on Wayland
e.g: All nividia drivers crash or do not work - #3 by KeifferMonster

Try using the 555 driver.
https://wiki.nixos.org/wiki/Nvidia#Determining_the_correct_driver_version

It is currently under the beta package.

hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.beta;

555 is now out of beta, and landing in NixOS unstable as nvidiaPackages.latest shortly:

https://nixpk.gs/pr-tracker.html?pr=322963

The wiki should be updated when this happens. Currently it doesn’t even mention the “latest” option.

How do I define 555 as the package I want if I am on NixOS 24.05?

I have been using nix for a while now but have never touched flakes or anything like that

You can use any driver version even before it has reached nixpkgs. In this case:

hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.mkDriver {
    version = "555.58";
    sha256_64bit = "sha256-bXvcXkg2kQZuCNKRZM5QoTaTjF4l2TtrsKUvyicj5ew=";
    sha256_aarch64 = "sha256-7XswQwW1iFP4ji5mbRQ6PVEhD4SGWpjUJe1o8zoXYRE=";
    openSha256 = "sha256-hEAmFISMuXm8tbsrB+WiUcEFuSGRNZ37aKWvf0WJ2/c=";
    settingsSha256 = "sha256-vWnrXlBCb3K5uVkDFmJDVq51wrCoqgPF03lSjZOuU8M=";
    persistencedSha256 = "sha256-lyYxDuGDTMdGxX3CaiWUh1IQuQlkI2hPEs5LI20vEVw=";
};

This did it. Everything seems to work great now on 555. Thanks!

For reference 555.58 is latest in NixOS unstable branch atm.

{ config, ... }:

let
  unstable = import <nixos-unstable> {
    config = {
      allowUnfree = true;
    };
  };
in
{
  boot.kernelPackages = unstable.linuxPackages_latest;

  hardware.nvidia = {
    package = config.boot.kernelPackages.nvidiaPackages.latest;

    ...
  };
}
