Does hw/xfree86 layer allow people write a virtual server like Xvnc? Or we should switch back to old DDX layer? dware 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. > (X11R5 era, though some basic concepts are still unchanged) > > -- > -Alan Coopersmith- alan.coopersm...@oracle.com > Oracle Solaris Platform Engineering: X Window System _______________________________________________ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg
