I have installed desktop on my Ubuntu Server using apt-get install ubuntu-desktop. The server is hosted somewhere so I don't have its physical access and I connect it through VNC (using ssh tunnel).
But the VNC viewer shows just a black dotted screen (screenshot is attached).
Can you please help me in sorting this out? It would be difficult for me to reboot the machine since it is being used 24/7.
"... It seems that vncserver is not able to export display :0 but it opens another one where a window manager has to be loaded all over again and we don't want that.. ;)
In that case, install the package called x11vnc - which exports the current display, not a new one.."
