Great!

That's all you probably need, read on.

Does it accept the xdmcp options (-broadcast, -query ..)? Then it will be a
great Xserver!

There might be something like local looping which can cause a problem. Best
to use an other machine to run vncviewer.

Do you have the vncserver for M$Windows also running? That might cause a
problem if you run on display :0. Try to put one of them on :1 or any other
display number.

Keep in mind: the X protocol uses port (6000 + display) just as vnc uses
port (5900 + display). Are both ports free? or do you happen to have a
Xserver already running at your machine?

btw, I expect no firewalling running...

Does the webserver also run properly?

Sonds like you get a connection. Your log points me to loopback problems.
