Re: Is Xvnc a X exension or X driver?
While I'm not interested in writing a manual, I am trying to round up and organize existing docs and info. and I am really interested in any diagrams and such that people might have/know of for Xserver internals or how different pieces interact. If anyone has any docs/diagrams/handscanned cocktail napkins they find useful or helpful, please send me a like or copy. thanks, Matt On Mon, Apr 19, 2010 at 11:08 PM, Alan Coopersmith alan.coopersm...@oracle.com wrote: (I've cc'ed xorg-devel, since this is really much more of a developer topic than a user topic.)

I suppose once you add the vnc loadable extension to that, it's pretty much like Xvnc. -- -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
Is Xvnc a X exension or X driver?
Hi experts: I am looking into code of tigervnc, the Xvnc contains a vnc X server which seems a X driver or extension ( it locates at tigervnc-1.0.1/unix/xserver/hw/vnc). 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. Thank you.
