Help

Crapping out was what I mentioned above…hangs when launching sddm. This is my config. Thank you.

{ config, lib, pkgs, ... }:
{

  hardware.graphics = {
    enable = true;
  };

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

  hardware.nvidia = {
    modesetting.enable = true;
    open = false;

    nvidiaSettings = true;

    prime = {
      sync.enable = true;
      intelBusId = "PCI:0:2:0";
      nvidiaBusId = "PCI:1:0:0";
    };

  };
}
