VNC includes an X extension, but Xvnc itself is an X server using the hw/vnc DDX layer. Originally X support for different hardware was delivered by having a different DDX layer for each, resulting in multiple different X servers and changing X servers to use different types. In the current code, the hw/xfree86 layer provides a common DDX layer for many types of hardware with loadable driver modules for each type, but there are still other DDX layers for other types of X server, such as Xvnc, Xvfb & Xnest, as well as the kdrive DDX layer which supports multiple hardware types using the older model of per-hardware X server binaries. > Could anyone point me a programming howto followed by above > implementation? > I gone through documentations on X.org, but didn't find programming > manual of such a extension/driver. There isn't a lot of up-to-date documentation on X server internals - not many people are interested in spending the huge amounts of time required to write a programming manual that less than 100 people will ever read. Documents that do exist (though not necessarily completely up-to-date): * Definition of the Porting Layer for the X v11 Sample Server: html: http://www.x.org/releases/X11R7.5/doc/core/Xserver-spec.html pdf: http://www.x.org/releases/X11R7.5/doc/core/Xserver-spec.pdf * The X Window System Server, Elias Israel, Erik Fortune, Digital Press, ISBN 1-55558-096-3, 1993.
