[gtk-vnc-devel] patch to allow use with OS X Screen Sharing

[Jin Choi <jsc alum mit edu>]

Using gtk-vnc-3.4 through vinagre on Ubuntu (hardy), any attempt to 
connect to an OS X Leopard machine with screen sharing on resulted in an 
immediate closed connection.

This thread gives some idea of what's going on:

It seems AppleVNCServer advertises RFB 003.889, which would indicate 
that it speaks RFB 3.8, but really only speaks some variant of RFB 3.3.

I applied the following patch to gvnc.c to smash the minor version to 3 
when presented with a minor version of 889 (similar to what appears to 
be done to support for UltraVNC), and now vinagre can connect to the OS 
X box.

Sadly, the performance is much slower than tightvncviewer....
