Polo: a new Wayland compositor for MATE
MATE is probably the last X11-only holdout among the major desktop environments, but that's about to change if Kerem Soke has anything to say about it.
Polo is a port of Marco's behavior and window management policies to Wayland, built on libweston and written in Vala and C. It's a window manager, compositor, and session authority for the MATE Wayland desktop. It takes over, step by step, what Marco, mate-session-manager and the compositor-facing parts of mate-settings-daemon do on X11.
Polo's GitHub page
Soke is looking for testers with this very first Polo 1.0.0 release - cute name, too - which is available on its GitHub page.
