Well, you can always install the vnc packages that come with ubuntu. As 
far as I know (expect), the vnc4server package does include the current 
Xvnc binary. You can always get your old sources, build with the 
libraries and replace the binary to see what's happening. The reason to 
install the package first is that all other configuration is already 
there. As far as I know Xvnc is relaxed to unknown or strange options, 
so your (older?) binary might just work.

I've used Xvnc on :0 since day 0. However, that was on 'headless' 
servers ;-). You mean that vnc on unix acts as vnc on msWindows. That is 
possible since a long time too, depending on the X11 server or Display 
manager you use. Some X11 servers can be extended with a vnc-module (the 
linux ones for example) Display managers (or session managers) like KDE 
and Gnome also have modules and/or hooks to provide a vnc-view to the 
desktop. Finally, there is (was) also vnc-server that could co-exist 
with a frame-buffer device, which works entirely like the msWindows vnc 
server: just peek at the framebuffer and forward the changes. So far for 
the history lesson.

For your remote view at your desktop in Ubuntu: System -> Preferences -> 
RemoteDesktop. Just select what you like and off you go.
