VNC on Ubuntu

    I’ve kind of got VNC working on Ubuntu but not well, it starts up in like 1028×768 screen size, 8-bits, and if I try to change the setting for the monitor, which works fine under CentOS 6, it says Xrandr extension not found.

     I can’t find the configuration file for tightvnc server, no idea where that is, the documentation is pretty much worthless to non-existent.  I have no idea how the vnc server actually gets started on this machine as there is no start-up script in /etc/init.d, nor is there any line in /etc/initd.conf.

     Anybody familiar with this beast that could give me some pointers, it would be much appreciated.
