I used to run the default VNC server (/usr/lib/vino/vino-server) but it is unable show VirtualBox VMs. So, I have installed TurboVNC, which is designed to support 3D and shows my VirtualBox VMs all right.
However, TurboVNC and all these other TightVNC derivatives run on 5901 or 5902. I would like to make them run on 5900 but there doesn't seem to be an option to do so.
How can I run Turbo, Tiger, Tight VNC servers on port 5900. If I could do this, then I could make TurboVNC the default VNC server on several computers and VMs.
(I know that VirtualBox has an RDP option but I want to see the host desktop along with the VMs too. So, TurboVNC on the host is my choice.)
