Support multiple screens with webOS and Qt

on YouTube ↗28m

" summary

Shows a concrete implementation that runs multiple physical screens from one webOS device using Qt and Wayland: the compositor creates one compositor with multiple compositor windows mapped to DRM connectors/platform screens, clients pick a screen via display affinity, and input devices are mapped to displays with dynamic USB handling. Adds per-display virtual keyboard servers and tweaks to Qt window activation and cross-window property sharing. Demo IVI setup (front/center/rear) runs and moves content between screens.
