Greetings,
Fresh convert over to nixOS,
Just as a forward - while I would hardly call myself a linux master, I do use it for work everyday (more debian based), and have been running it as my daily home driver for the past 16-18 months.
Took the plunge over to Nix and am really excited however I just am not sure if I setup my nvidia card correctly. Something just feels off.
First the code:
# lshw -c display
*-display UNCLAIMED
[...]
bus info: pci@0000:01:00.0
[...]
configuration: latency=0
resources: memory:a3000000-a3ffffff memory:90000000-9fffffff memory:a0000000-a1ffffff ioport:5000(size=128) memory:a4000000-a407ffff
*-display
[...]
bus info: pci@0000:00:02.0
[...]
configuration: driver=i915 latency=0
resources: irq:143 memory:a2000000-a2ffffff memory:80000000-8fffffff ioport:6000(size=64) memory:c0000-dffff
So from the “driver=i915” I am making the assumption that this is my Intel integrated and thus PCI:01:00 is the Nvidia
Thus my config nix has
# Graphics Drivers ###########################
# Enable OpenGL
hardware.opengl = {
enable = true;
driSupport = true;
driSupport32Bit = true;
};
# Load nvidia driver for Xorg and Wayland
services.xserver.videoDrivers = ["nvidia"];
hardware.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

# 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;
# Optionally, you may need to select the appropriate driver version for your specific GPU.
package = config.boot.kernelPackages.nvidiaPackages.stable;
};
hardware.nvidia.prime = {
sync.enable = true;
# Make sure to use the correct Bus ID values for your system!
nvidiaBusId = "PCI:1:0:0";
intelBusId = "PCI:0:2:0";
};

Yes I copied / pasted / edited and left the comments hah.
Unfree repos are enabled in the config also fwiw
Post rebuilt-switch:
everything loads great, and runs smooth but
nvidia-smi – doesnt give any output just errors
“NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.”
lspci gives me hope that its right
00:02.0 VGA compatible controller: Intel Corporation CoffeeLake-H GT2 [UHD Graphics 630]
01:00.0 3D controller: NVIDIA Corporation GP107GLM [Quadro P2000 Mobile] (rev a1)
So I guess I just am curious if
- I can ignore the nvidia-smi error, false positive, just nvidia things
- Any performance issues in getting a game to run would be something I want to look at a per application base? such as steam run commands etc?
FWIW - I did try offload and had the same issue with nvidia-smi… also Sync sounds better to me, I dont game really ever, mostly just working in VMs but its nice every once and a while I suppose. I just want as much performance out of this laptop as i can get.
Hope thats enough info - apologies for the 50000th Nvidia question, i did try and search things up but wasnt making headway after a couple hours.
Thx!
