In a Wayland system, you must have: - exactly one compositor (which doesn't use Wayland) - zero or more applications using Wayland But that only makes sense if you have two or more. If you have only one, there's no need to launch the compositor to composite that single application's output. Just have the application output directly to whatever the compositor was using as a backend. Which is also the exception: when the backend of the compositor is not something directly supported by Qt. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
