@nek0 , what did you do to make it work?

I put this in my configuration.nix and it didn't do anything:

  nixpkgs.config = {
    allowUnfree = true;
    
    packageOverrides = super: let self = super.pkgs; in
    {
        linuxPackages = super.linuxPackages_latest.extend (self: super: {
          nvidiaPackages = super.nvidiaPackages // {
            stable = self.nvidiaPackages.stable_390;
          };
        });
    };
  };

@sib-null You also need the following line in your configuration.

services.xserver.videoDrivers = [ "nvidia" ];
