Hyprland on NixOS with nvidia driver - screenshare worky edition

README.md

Screensharing on Hyprland (NVIDIA + NixOS)

here is my configuration if you want to see it in practice https://github.com/sioodmy/dotfiles/tree/f881916328fcb13ffaf7c436a7f0fa2c28103273

Add hyprland's flake and nixpkgs-wayland to your flake inputs

hyprland.url = "github:hyprwm/Hyprland/";
nixpkgs-wayland.url = "github:nix-community/nixpkgs-wayland";

Enable nixpkgs-wayland overlay

nixpkgs.overlays = [inputs.nixpkgs-wayland.overlay];

Tweak your configuration.nix

let
  dbus-hyprland-environment = pkgs.writeTextFile {
    name = "dbus-hyprland-environment";
    destination = "/bin/dbus-hyprland-environment";
    executable = true;

      systemctl --user start pipewire pipewire-media-session xdg-desktop-portal xdg-desktop-portal-wlr
    '';
  };

Patch hyprland
