Which free remote system such as VNC or similar is known to work on 14.04 cloud

Below method works for me.

Install desktop with minimal packages.

sudo apt-get install --no-install-recommends ubuntu-desktop

Install few gnome packages to load VNC properly.

sudo apt-get install gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal

Install vnc4server

sudo apt-get install vnc4server

Open /usr/bin/vncserver

Find "# exec /etc/X11/xinit/xinitrc\n\n". line and add these lines below

      "# exec /etc/X11/xinit/xinitrc\n\n".
       "gnome-panel &\n".
       "gnome-settings-daemon &\n".
       "metacity &\n".
       "nautilus &\n".
       "gnome-terminal &\n".

Start vncserver

vncserver

Afetr starting session , you could access VNC with your IP and session ( 12.34.56.78:1 )
