A guide on setting up x11vnc to remotely access your Ubuntu Desktop via VNC (While you are not in the same location).
This guide assumes you can access your Desktop via ssh.
Remote Desktop setup:
On the destination machine, install the x11vnc package
sudo apt-get install x11vnc
You should now create a password for accessing your VNC session – Note this will be stored within your home directory by default:
Running the VNC server:
The below command will run the VNC server in the foreground so it is easily closeable once you have done what you needed from the Desktop of the machine.
x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth ~/.vnc/passwd -rfbport 5900 -shared
