Hello,
I just got a System76 Serval laptop, and I’m struggling to get Xorg working with the nvidia drivers. My card is an RTX 4060:
[little-dude@nixos:~]$ nix-shell -p pciutils --run "lspci -nn | grep VGA"
00:02.0 VGA compatible controller [0300]: Intel Corporation Raptor Lake-S UHD Graphics [8086:a788] (rev 04)
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation AD107M [GeForce RTX 4060 Max-Q / Mobile] [10de:28e0] (rev a1)
And I tried many variants of the following config:
{ config, pkgs, ... }:
{
imports = [ ./hardware-configuration.nix ];
nixpkgs.config.allowUnfree = true;
boot.loader = {
systemd-boot.enable = true;
efi.canTouchEfiVariables = true;
};
hardware = {
opengl = {
enable = true;
driSupport = true;
driSupport32Bit = true;
};
nvidia = {
# Modesetting is required.
modesetting.enable = true;
# Nvidia power management. Experimental, and can cause sleep/suspend to fail.
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+
# Do not disable this unless your GPU is unsupported or if you have a good reason to.
open = true;
# Enable the Nvidia settings menu,
# accessible via `nvidia-settings`.
nvidiaSettings = true;
# We have a GeForce RTX 4060 which is not in the legacy GPU list (https://www.nvidia.com/en-us/drivers/unix/legacy-gpu/)
# Therefore, the stable drivers should work.
package = config.boot.kernelPackages.nvidiaPackages.stable;
prime = {
offload = {
enable = true;
enableOffloadCmd = true;
};
intelBusId = "PCI:1:0:0";
nvidiaBusId = "PCI:0:2:0";
};
};
};

}
Xorg fails to start:

The full boot logs can be found here
I tried several variants of this:
- stable drivers,
open = false;prime enabled: gist - beta drivers,
open = true;prime enabled: gist - beta drivers,
open = false;, prime enabled: gist - beta drivers,
open = true;` prime disabled: gist
When prime is disabled, the logs show that Xorg starts. However, the screen remains black… Moreover, since this is a laptop I do want prime enabled anyway. Wrt to my prime config, here is where I got the bus numbers from:
