commit 0557101a42bf0d27cac809a9c8ce3380559bc6c3
Author: Robert Bragg <robert linux intel com>
Date: Sat Jan 7 22:21:32 2012 +0000
wayland: Adds basic hybrid X + Wayland support
This adds support for running mutter as a hybrid X and Wayland
compositor. It runs a headless XWayland server for X applications
that presents wayland surfaces back to mutter which mutter can then
composite.
This aims to not break Mutter's existing support for the traditional X
compositing model which means a single build of Mutter can be
distributed supporting the traditional model and the new Wayland based
compositing model.
TODO: although building with --disable-wayland has at least been tested,
I still haven't actually verified that running as a traditional
compositor isn't broken currently.
Note: At this point no input is supported
Note: multiple authors have contributed to this patch:
