Wayland is a computer protocol that specifies the communication between a display server and its clients, as well as a reference implementation of the protocol in the C programming language.
Wayland's main goal is replacing the X Window System with a modern, simpler windowing system in Linux and other Unix-like operating systems. The project's source code is published under the terms of the MIT License, a permissive free software licence.
As part of its efforts, the Wayland project also develops a reference implementation of a Wayland compositor called Weston.
Xresources won't load
This is a known issue. Back in 2015, it was decided that the resources were too slow to load and that was dropped from the main GNOME session, see Redhat's bugzilla for more information.
Workaround: run this by hand or setup something to start it up automatically on session login.
xrdb -load .Xsession
