x11VNC on Ubuntu 14.04

[Doug Penner]

I would also try testing without using the flip at all, just in case there 
was a change in one of the protocols or implementations that causes the 
flip to no longer function correctly. Without knowing how your flip works 
makes it difficult to rule it out.

Basically, start from the very basic, simplest implementation (connect to 
localhost), then start re-adding your complexity (remote connection, new 
port, port flip, ssh tunnel, etc) slowly until it breaks.
