I have been trying to get my Nvidia card working, using offloading (as it seemed the simplest option).
I have the 4070 (laptop version).
I have pulled and put together all the configs from the Nvidia modules in the hardware repo and the items from the wiki. At the moment, I am not consuming the code from the hardware repo (my laptop model is not supported yet), and wanted all my Nvidia config in a single spot until I get this working.
Essentially, nvidia-smi nor nvidia-settings see the card. I searched this site, and the other fixes do not seem to apply.
Config:
{ lib, pkgs, config, ... }:
{
# NVIDIA drivers are unfree.
nixpkgs.config.allowUnfree = pkgs.lib.mkForce true;
# Sets the default video driver for the X server and Wayland to "nvidia"
services.xserver.videoDrivers = lib.mkDefault [ "nvidia" ];
hardware = {
opengl = {
# Enables the graphics driver for OpenGL
enable = true;
# Enables Direct Rendering Infrastructure (DRI), which allows the graphics driver to directly render graphics, improving performance in OpenGL
driSupport = true;
# Enables 32-bit Direct Rendering Infrastructure (DRI) support, which allows the graphics driver to directly render graphics in 32-bit applications using OpenGL
driSupport32Bit = true;
# Adds the 'vaapiVdpau' package to the extra packages for OpenGL
extraPackages = with pkgs; [ vaapiVdpau ];
};
nvidia = {
# Modesetting is required.
# Since NVIDIA does not support automatic KMS late loading, enabling DRM (Direct Rendering Manager) kernel mode setting is required to make Wayland compositors function properly, or to allow for Xorg#Rootless_Xorg.
modesetting.enable = true;
# Nvidia power management. Experimental, and can cause sleep/suspend to fail.
# Enable this if you have graphical corruption issues or application crashes after waking
# up from sleep. This fixes it by saving the entire VRAM memory to /tmp/ instead
# of just the bare essentials.
powerManagement.enable = false;
# Fine-grained power management. Turns off GPU when not in use.
# Experimental and only works on modern Nvidia GPUs (Turing or newer).
powerManagement.finegrained = false;
# Use the NVidia open source kernel module (not to be confused with the
# independent third-party "nouveau" open source driver).
# Support is limited to the Turing and later architectures. Full list of
# supported GPUs is at:
# https://github.com/NVIDIA/open-gpu-kernel-modules#compatible-gpus
# Only available from driver 515.43.04+
# Currently alpha-quality/buggy, so false is currently the recommended setting.
## Confirmed my card is in there.
open = true;
# Enable the Nvidia settings menu,
# accessible via `nvidia-settings`.
nvidiaSettings = true;
# Optionally, you may need to select the appropriate driver version for your specific GPU.
package = config.boot.kernelPackages.nvidiaPackages.stable;
prime = {
offload = {
enable = true;
enableOffloadCmd = true; # Provides `nvidia-offload` command.
};
# Bus ID of the Intel GPU. You can find it using lspci, either under 3D or VGA
intelBusId = "PCI:0:2:0";
# Bus ID of the NVIDIA GPU. You can find it using lspci, either under 3D or VGA
nvidiaBusId = "PCI:1:0:0";
};
};
};
}
#### NOTES
# Get BusID:
# lspci | rg "VGA|3D controller"
# it will be in hexadecimal format, convert it to decimal

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
OK, I was going down the road of the article, then I noticed it is for the “super”. Which I do not believe this 4070 is. (Since it is a laptop GPU).
I also noticed this time around that the wiki highlights:
Note: As of early March 2024 the production driver has been updated from 535 to 550. This is a breaking change for some people, especially those on Wayland. To resolve this follow the steps under Running the new RTX SUPER on nixos stable.
So I moved over to package = config.boot.kernelPackages.nvidiaPackages.production; but unfortunately it did not help.
So, after the change, I checked journalctl again:
