VNC on Xubuntu topic

Hello all

First time with Linux.

I have followed the instructions on the guide here:
http://robot.wpi.edu/wiki/index.php/...ntu_VNC_Server

I am to the line that says "Turbo VNC" after "Automatically Start The Server"
I am unable to log into Xubuntu from either a Mac (10.6.8) using Chicken of the VNC or Windows 7 using TightVNC.
I left the port alone at first then changed it to 5907 since I have another machine on the network using 5901 and thought maybe an issue and still nothing.
This is all being tested internal on the same lan, not from the outside.

On either Mac or Windows clients am usig 10.0.0.10:5907 (and 10.0.0.10:5901 prior to changing the port)

My IPs are:
xUbuntu = 10.0.0.10
Mac = 10.0.0.33
Windows = 10.0.0.201
All are on the same LAN: 10.0.0.0/24

I dont know if I have to setup the TurboVNC part but if do I dont understand how to do that.
All it says on the guide is:

/opt/TurboVNC/bin/vncserver &

I looked in /opt/ and there is no TurboVNC directory so I tried typing that in to the terminal and got:

maurice@DellE5500:~$ /opt/TurboVNC/bin/vncserver &
[1] 3437
bash: /opt/TurboVNC/bin/vncserver: No such file or directory
maurice@DellE5500:~$

So am thinking I need to install TurboVNC?????
How do I do that?

My current start up script at /etc/init/x11vnc.conf:
start on login-session-start
script
x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -forever -shared -bg -o /var/log/x11vnc.log -rfbauth /etc/x11vnc.pass -rfbport 5907 -localhost
end script

And right before changing to port 5907:
start on login-session-start
script
x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -forever -shared -bg -o /var/log/x11vnc.log -rfbauth /etc/x11vnc.pass -rfbport 5901 -localhost
end script

and I have restarted the computer and let it both log in to the desktop as well as left it at the login screen.

Thanks much in advance
