Getting Help for Configuring Nvidia driver on NixOS 22.11

Anifyuli · January 30, 2023, 4:47pm

Hello everyone. I’m very new in NixOS ecosystem.
I want to configure Nvidia driver on my laptop, but I get confusing things in setup process. I inputted this configs in configuration.nix :

# Allow unfree packages
  nixpkgs.config.allowUnfree = true;
  
  # Configuring Nvidia PRIME
  hardware.nvidia.nvidiaSettings = true;
  services.xserver.videoDrivers = ["nvidia"];
  hardware.opengl.enable = true;
  hardware.nvidia.modesetting.enable = true;
  hardware.nvidia.prime = {
   offload.enable = true;

   # Bus ID of the NVIDIA GPU. You can find it using lspci, either under 3D or VGA
   nvidiaBusId = "PCI:1:0:0";

   # Bus ID of the Intel GPU. You can find it using lspci, either under 3D or VGA
   intelBusId = "PCI:0:2:0";
  };
  hardware.opengl.driSupport32Bit = true;
  hardware.nvidia.powerManagement.enable = true;
  
  # Optionally, you may need to select the appropriate driver version for your specific GPU.
  hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.stable;

But, Nvidia X Server Settings not showing GPU info and GNOME Settings can’t detect my GPU. I have comparisons from Fedora 37 (I dual boot with Fedora)

NixOS

Fedora 37

My questions is what should I do to solve this problem?
Thank you very much. Sorry My English

My NVIDIA settings GUI looks the same as yours, yet my GPU works.

Run nvidia-smi and see if Xorg (X11) is shown as one of the processes.

Then run __NV_PRIME_RENDER_OFFLOAD=1 glxinfo to check if offload rendering is working.

In the first case you are using wayland

TLATER · January 31, 2023, 5:20pm

Did you find the GPU with lspci as the config mentions? Can’t help but notice it’s the exact same bus ID as the ones from the wiki, I’ve not seen those repeated in the wild before.

Also, what laptop are you using? Have you checked GitHub - NixOS/nixos-hardware: A collection of NixOS modules covering hardware quirks. to see if someone has already configured your laptop before?

Lenovo Towers look to use this ids typically

Anifyuli · January 31, 2023, 10:20pm

Yes, same as you. In nvidia-smiI get a process

But, I haven’t glxinfo. How I install it? My inxi missed tools such as glxinfo

I think I have mistakes after checking lspci. I will try to change it immediately.
For nixos-hardware, my laptop or family types of my laptop (such as VivoBook, UltraBook, TUF, etc) is not listed on here. Only ROG series in here

Anifyuli · January 31, 2023, 10:26pm

I use Xorg or Wayland only get it in my NixOS setup

emmanuelrosa · January 31, 2023, 10:58pm

You can get glxinfo with nix-shell -p glxinfo

Anifyuli · January 31, 2023, 11:06pm

Okay, I will write it on configs

Anifyuli · January 31, 2023, 11:24pm

I edit my configs following lspci result, and executing __NV_PRIME_RENDER_OFFLOAD=1 glxinfo, but it’s not changing anything.

What should I do again?

emmanuelrosa · February 1, 2023, 9:08am

What does nvidia-smi show?

Based on a prior post, it looks like you had offload rendering configured correctly at some point.

Anifyuli · February 1, 2023, 10:45pm

You can read my recent reply. I ask to you how to install glxinfo and I post my nvidia-smi value

nrdxp · February 1, 2023, 10:53pm

If you are indeed using render offload and it appears that you are, then nvidia-settings doesn’t show anything currently. I opened a ticket for this a while back:

github.com/NixOS/nixpkgs

NV_CONTROL (nvidia-settings) is non-functional

0.kind: bug

### Describe the bug On a NixOS unstable from earlier today running `nvidia-s…ettings -q all` returns nothing. Also launching the GUI doesn't allow for any settings. If I try to run `gwe` from the cli, it informs me that the "nv-control x extension is not found". These tools used to work several years ago, but something has broken since then. ### Steps To Reproduce Steps to reproduce the behavior: `nvidia-settings -q all` ### Expected behavior I need `nvidia-settings` to control my GPU fans, so I would like it to function as expected ### Screenshots ![2022-08-19_23-08-1660973451](https://user-images.githubusercontent.com/34083928/185730477-52b133d4-0a71-4724-90bf-0a354c3a0adf.jpg) ### Additional context Not sure if it is something specific to my setup (PRIME laptop with render offload) or if it is broken for everyone? ### Notify maintainers  ### Metadata Please run `nix-shell -p nix-info --run "nix-info -m"` and paste the result. ```console - system: `"x86_64-linux"` - host os: `Linux 5.15.54-xanmod1, NixOS, 22.11 (Raccoon), 22.11.20220819.1882611` - multi-user?: `yes` - sandbox: `yes` - version: `nix-env (Nix) 2.10.3` - nixpkgs: `/nix/store/jqqk07gssjg81hzas06966cdczg83c8v-z72lgm9v5mlq5819wa9a5qbbijz5x4rv-source` ```

I anecdotally remember it working before, but it could just be a faulty memory. Unfortunatly I have no idea how to debug further, but the good news is that most functionality of your GPU should work, you just won’t see any information about it in the nvidia-settings GUI.

Anifyuli · February 1, 2023, 11:08pm

Thanks, Mister for forwarding to NixOS issue repos. So better conclusion from my problem is waiting for this problem fixed?

nrdxp · February 1, 2023, 11:55pm

Well you don’t have to wait to actually use your GPU, since it works properly with render offload. You just won’t see any information about it in the nvidia-settings GUI until this is fixed. You can still view information abou the GPU and apps it currently has loaded with nvidia-smi as mentioned.

Anifyuli · February 2, 2023, 1:20am

So, can I install switchheroo-control to launch apps with Nvidia GPU?

nrdxp · February 2, 2023, 4:33pm

I dunno, I’ve never used that particular program. But I believe newer versions of gnome have a built in “launch with dGPU” option in the context menu (right-click).

There are a few environmental variables you can set to manually launch any program with the dGPU as well. There is a small little script for accomplishing that outlined in the wiki:
