If it's an Intel iGPU + an Nvidia dGPU setup beware there's a bug with the implementation of the Nvidia driver currently which breaks connecting external displays on X11 depending on your hardware. See https://github.com/NixOS/nixpkgs/issues/199024 https://github.com/NixOS/nixpkgs/issues/199024 and the comments of https://github.com/NixOS/nixpkgs/pull/165188 https://github.com/NixOS/nixpkgs/pull/165188. Also setting Coolbits doesn't seem to work either on my end, which means no overclocking support for the Nvidia GPU (if that's something you care about).
