Fix bumblebee kernel panic

Help
1

Hello world,

I’m just beggining to set up my first NixOS on my Laptop (MSI GS73 VR 6RF) which has an optimus NVIDIA GPU.

Optimus works fine, but when I try to set hardware.bumblebee.enable = true;, I get a kernel panic.

I have seen that this error can be fixed by a workaround : All boots with bumblebee ends with kernel panic · Issue #205 · Bumblebee-Project/Bumblebee · GitHub
Basically, the workaround is done by delaying the bumblebeed startup.

How can I add this sleep 2 command before bumblebee starts ?
Do I have to do some sort of editing on bumblebee.nix:89 ?

My current configuration if that’s of any help :

{ config, pkgs, ... }:

{
  imports =
    [ # Include the results of the hardware scan.
      ./hardware-configuration.nix
    ];

  ### Boot
  # Use the systemd-boot EFI boot loader.
  boot.loader = {
    systemd-boot.enable = true;
    efi.canTouchEfiVariables = true;
    grub = {
      enable = true;
      version = 2;
      efiSupport = true;
      useOSProber = true;
      devices = ["nodev"];
    };
  };
  
  ### NixPkg
  nixpkgs.config.allowUnfree = true;
  
  ### Nvidia configuration
  # hardware.nvidia.optimus_prime.enable = true;
  # hardware.nvidia.optimus_prime.nvidiaBusId = "PCI:1:0:0";
  # hardware.nvidia.optimus_prime.intelBusId = "PCI:0:2:0";
  hardware.bumblebee =  {
    enable = true;
  };

  ### Other hardware
  sound.enable = true;
  # hardware.pulseaudio.enable = true;
  
  ### Network
  networking.hostName = "akame";
  networking.networkmanager.enable = true; # Networking via Network Manager
  # networking.wireless.enable = true;  # Wireless support via wpa_supplicant

  # networking.proxy.default = "http://user:password@proxy:port/";
  # networking.proxy.noProxy = "127.0.0.1,localhost,internal.domain";
  
  # Firewall.
  # networking.firewall.allowedTCPPorts = [ ... ];
  # networking.firewall.allowedUDPPorts = [ ... ];
  # networking.firewall.enable = false;

  ### Internationalisation
  i18n = {
    consoleFont = "Lat2-Terminus16";
    consoleKeyMap = "fr";
    defaultLocale = "fr_FR.UTF-8";
  };
  time.timeZone = "Europe/Paris";

  ### System packages & services
  environment.systemPackages = with pkgs; [
    wget vim git
  ];

  # Some programs need SUID wrappers, can be configured further or are
  # started in user sessions.
  # programs.mtr.enable = true;
  # programs.gnupg.agent = { enable = true; enableSSHSupport = true; };

  services.openssh.enable = true;
  # services.printing.enable = true;
  
  ### Display
  # Enable the X11 windowing system.
  services.xserver = {
    enable = true;
    layout = "fr";
    libinput.enable = true; # Enable touchpad support.
    # xkbOptions = "eurosign:e";
    # videoDrivers = [ "intel" ];

    # Enable the KDE Desktop Environment.
    displayManager.sddm.enable = true;
    desktopManager.plasma5.enable = true;
  };

  ### Users
  # Define a user account. Don't forget to set a password with ‘passwd’.
  users.users.arsleust = {
    ...
  };
}

Thanks !

Cheers,
Guillaume

Looking at the general specifications in the model’s page, with a GTX 1060, the preferred method should be NVIDIA’s “native” prime render offload solution which isn’t really implemented in nixpkgs yet [1] but is being worked on at the moment.

Thank you very much, I’ll be following that… :slight_smile:

EDIT : I’m curious as to which “general specifications in the model’s page” you are referring to

The normal specifications of the model assuming it hasn’t been internally meddled with and/or changed.
