Under the leadership of Novell's David Reveman, Novell has sponsored and led the development of this powerful new graphics subsystem for Linux since late 2004. Xgl is the X server architecture layered on top of OpenGL and takes advantage of available accelerated 3D rendering hardware. It is designed to integrate well with the composite extension and performs best when a compositing manager is running. 'Compiz' is the new OpenGL compositing manager from Novell and is the framework that enables the development of graphical plug-ins.

This looks really cool.

It does look very cool. It has the potential to bring the Linux graphical system up to date with OSX and Windows Vista.

There were some issues during the development of the code not being properly distributed, but Novell and Reveman were very good about fixing the issue as soon as it was pointed out to them.
