Hi everyone! I’m setting up NixOS on my laptop, which has two GPUs, and I’m running into a couple of issues. I’m hoping someone can help me out.
After I install NVIDIA proprietary driver (560):
- The Brave browser doesn’t work.
- When launching Sway with
--unsupported-gpu, I get a message indicating that it’s using the NVIDIA proprietary driver, but I want Sway to use my AMD iGPU.
My nvidia.nix file here:
{ config, pkgs-unstable, ... }:
{
environment.systemPackages = with pkgs-unstable; [
glxinfo
egl-wayland
vulkan-loader
];
services.udev.extraRules = ''
