Wayland Window Selection Fails

Wayland is the language (protocol) that applications can use to talk to a display server in order to make themselves visible and get input from the user (a person). The open source stack uses the drm wayland extension, which lets the client discover the drm device to use and authenticate and then share drm (gem) buffers with the compositor. Wayland is a protocol for a compositor to talk to its clients as well as a c library implementation of that protocol.

The wayland architecture integrates the display server, window manager and compositor into one process. You can think of wayland as a toolkit for creating clients and compositors. Wayland is a new display server and compositing protocol, and weston is the implementation of this protocol which builds on top of all the components above.

The wayland protocol provides clients a mechanism for sharing data that allows the implementation of copy-paste and drag-and-drop. Oct 22, 2012the 1.0.4 versions of wayland and weston were released. There are two separate asynchronous communication channels between xwayland and a wayland compositor:

One uses the wayland protocol, and the other one, solely for xwm, uses x11 protocol. It is used for internal wayland protocol features.
