Help installing NixOS using config from GitHub repo (newbie)

Help
1

Hi! I’m new to NixOS and really want to set up my system using a pre-made configuration, but I’m a bit confused.

I found this repository with configs:
:link: https://github.com/librephoenix/nixos-config

I want to use this config to install NixOS, but I’m not sure where to start or how to properly apply it. I also need to install NVIDIA drivers (my GPU is an RTX 4060), and it looks like the config has something related to that — but I’m not sure if it’s set up correctly for my system.

My system specs:

  • GPU: NVIDIA RTX 4060
  • CPU: AMD Ryzen 5 5600

I’d really appreciate if someone could:

  1. Explain how to properly use the config from this repository for installation.
  2. Help me edit the config for my specific hardware, if needed.
  3. Make sure NVIDIA drivers are set up correctly, or help me do that.

I can provide output from lspci, nix-info, etc., if needed.

Thank you so much in advance :pray:

That’s okay?

The repository you link is set up for AMD GPUs. You could use it as a base, but you’re going to be changing a lot about it to make it match your system; it’s not designed with options to make this easy for you.

I’d really recommend starting from scratch, and looking at other repositories for tips instead. It looks like a pretty reasonable configuration to look at for that purpose.

As for your GPU, NVIDIA GPUs are a PITA to configure. I happen to have the exact hardware you do, though. YMMV but I’m working on a module for NVIDIA config: dotfiles/nixos-modules/nvidia/default.nix at 5c3d7d5365c859b23135b2acbd5807232e122271 · TLATER/dotfiles · GitHub

You could actually import the module, but for the time being I would recommend looking through the files involved and pretending you have withIntegratedGPU = false;. If you tell me which compositor/DE/WM you intend to use I can give additional tips.

It should boil down to this:

# nvidia.nix
{ config, pkgs, lib, ... }:
{
  services.xserver.videoDrivers = [ "nvidia" ];

  hardware.nvidia = {
    # This will no longer be necessary when
    # https://github.com/NixOS/nixpkgs/pull/326369 hits stable
    modesetting.enable = lib.mkDefault true;
    # Power management is nearly always required to get nvidia GPUs to
    # behave on suspend, due to firmware bugs.
    powerManagement.enable = true;
    # The open driver is recommended by nvidia now, see
    # https://download.nvidia.com/XFree86/Linux-x86_64/565.57.01/README/kernel_open.html
    open = true;
  };

  boot.extraModprobeConfig = "options nvidia NVreg_UsePageAttributeTable=1 NVreg_RegistryDwords=RMUseSwI2c=0x01;RMI2cSpeed=100";

  # Use firefox; the hardware accel does not support chrome
  hardware.opengl.extraPackages = [ pkgs.nvidia-vaapi-driver ];

  environment = {
    systemPackages = [ pkgs.libva-utils ];
    variables = {
      NVD_BACKEND = "direct";
      LIBVA_DRIVER_NAME = "nvidia";
      MOZ_DISABLE_RDD_SANDBOX = "1";
    };
  };

  programs.firefox.preferences = lib.mkIf cfg.firefox.enable {
    "media.ffmpeg.vaapi.enabled" = true;
    "media.rdd-ffmpeg.enabled" = true;
    "media.av1.enabled" = cfg.firefox.av1Support;
    "gfx.x11-egl.force-enabled" = true;
    "widget.dmabuf.force-enabled" = true;
  };
}

When trying to run the script with the NVIDIA module, I get an error.

error: path '/nix/store/v22rcxssmhjj2j481g07i1zp0y3a6437-source/modules/home/nvidia.nix' does not exist

If you’re using a flake in a git repository, you have to git add the file, too, since flakes copy the repository as reported by git to the nix store before evaluating (which happens to be the biggest flake misfeature IMO, albeit not because it prevents things not seen by git from being evaluated - though that’s still a huge issue, to be frank, at least as long as it doesn’t tell users about the problem).

It’s so hard to figure this out.

Maybe I could try using your NixOS configuration instead.

It’s a bit easier to start out with stable nix and find your way into how the system works IMO, than it is to start with flakes and all their baggage right out of the gate. npins are probably more worth recommending, but again, now I’m sending you down further third party things which means lots of doc reading about stuff you don’t understand yet.

Sadly the nix ecosystem is riddled with little papercuts like this and footguns are littered everywhere. It’s all pretty awesome when you’ve figured it out, but it can be tough to get started. Good luck, we’re here to support - share your configuration if you run into problems you don’t understand.

I wouldn’t recommend using other people’s NixOS configurations. Definitely not mine, at least.

They’re very purpose-built, and often need you to understand how they work to use them properly. If you ask for help with them, often they’ll be large and cumbersome, so people won’t be able to help you effectively.

Start with the default configuration that you generated during installation, and just add what you want to it. It’s a single file, so that really helps send it around for support purposes.

You’re probably right — I just want a beautiful and convenient system, that’s all.

It takes a bit of work. You’ve almost got the ingredients, though! Stylix is an important piece of the puzzle, the next is figuring out what WM/DE/compositor you want to use. GNOME is a good starting point for newbies. If you configure GNOME, and then use stylix to set some colors and pick a nice wallpaper, you’re basically there.

You can add further bells and whistles from there as you get more familiar with all of this :slight_smile:
