Re: VNC viewer on win XP-or-7, can not connect to ubuntu

[Arfin G. <Arf...@no...>]

Mel,

There are a couple of things that matter here.

1)  The default port for VNC is 5900 (the 5800 port is the browser/Java 
client port).

2)  Ubuntu -- at least up to 8.x -- running KDE or pretty much anything 
else, would not accept connections on the default port, as that would 
require sharing display 0 (zero).  The standard virtual display port 
number range for most Linux/Unix applications would start at 5901 
(display #1).  You would have to configure the VNC server to listen on 
one of those ports, and the connection would be established by (assuming 
5901) addressing either MyServerAddress:1 or alternatively 
MyServerAddress::5901.  (Notice that when using the "display number" 
notation, a single colon and the display number are used; when using the 
"port number" notation, a double colon and the full port number are used.)

3)  Ubuntu 10.x with KDE now supports -- as a default -- sharing display 
0 (zero), and their RFB (krfb) application assumes it.  I had to change 
my desktop to Gnome, because the new KDE 4 assumes that, if you create 
virtual sessions, you want to clone whatever is running on display 0.  
Further, it would launch applications in display 0 space even when the 
launch was initiated from the virtual session.  I have no idea what they 
were thinking when they made sharing display 0 the default.

Hope this information is of some use.
