xf4vnc

xf4vnc features

* Works with the Xfree86 v4.x codebase, which means new extensions like RENDER and GLX (which means OpenGL(tm)) are supported.

* All features from tightVNC 1.2.9 included, http://sf.net/projects/vnc-tight

* Ability to deliver events upon connection or disconnecting VNC clients.

* Provides a vnc.so to export your local console (aka :0) and the traditional Xvnc Xserver.

* Fast OpenGL direct rendering on VNC clients using Chromium http://chromium.sf.net

xf4vnc as the drop in replacement for Xvnc

Download the Xvnc-4.3.0.x-<os>.gz file and unpack it with gunzip <filename>. Then run 'chmod +x' on that file to make it executable. This is now your Xserver. For more information on configuring Xvnc your probably better off looking at the tightVNC projects pages. Goto http://www.tightvnc.com. As for the vncviewer replacement, when specifying the modular encodings you need to add '.so' to load the real module. For example.

vncviewer :1 -encodings "hextile.so copyrect.so"

xf4vnc for XFree86 exporting :0

NOTE: your XFree86.0.log file will produce errors regarding the loading of rfbkeyb and the rfbmouse drivers. This can safely be ignored as these drivers are embedded within the vnc.so binary. You'll get something like this...

(WW) Warning, couldn't open module rfbmouse
(II) UnloadModule: "rfbmouse"
(EE) Failed to load module "rfbmouse" (module does not exist, 0)
