#!/usr/bin/env bash
# Invoked by Sunshine as a stream-start hook (global_prep_cmd `do`).
# Creates/resizes a Hyprland headless output to match the connecting
# Moonlight client's resolution, and moves the active workspace onto it
# so the user's existing windows are visible on the stream.
# Resizes the vkms-backed `Virtual-1` connector to match the connecting
# Moonlight client's resolution, positions it adjacent to the existing real
# monitor(s), and (optionally) moves a content-bearing workspace onto it so
# the user sees something instead of an empty desktop.
#
# This script no longer disables eDP-* — vkms gives us a real DRM connector
# whose dmabuf is hardware-encoder-friendly, so Sunshine's `capture = kms`
# matches it unambiguously by name and we don't need to touch other outputs.
#
# Sunshine env vars set on connect:
# SUNSHINE_CLIENT_WIDTH, SUNSHINE_CLIENT_HEIGHT, SUNSHINE_CLIENT_FPS
