I personally use my laptop with an external display attached. In hybrid config it works nice only with Wayland, while X11 can't detect the external monitor. Everything works as expected in nvidia mode, but battery life is reduced then.

Setup at the time of testing

$ nix-info -m
 - system: `"x86_64-linux"`
 - host os: `Linux 6.1.62, NixOS, 23.05 (Stoat), 23.05.20231116.9fb1225`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.13.6`
 - channels(beko): `"home-manager-23.05.tar.gz"`
 - nixpkgs: `/nix/var/nix/profiles/per-user/root/channels/nixos`
