libXinerama provides an X Window System client interface to the XINERAMA
extension to the X protocol.
.
The Xinerama (also known as panoramiX) extension allows for multiple screens
attached to a single display to be treated as belonging together, and to give
desktop applications a better idea of the monitor layout.
