title: vnc session show gray screen on ubuntu
body: <p>I'm trying to install VNC server on Ubuntu 14 LTS.
  I installed the "vnc4server" package and started vncserver simply by:
  "vncserver" command line.
  (like: <a href="http://www.howtoforge.com/how-to-install-vnc-server-on-ubuntu-14.04" rel="nofollow">http://www.howtoforge.com/how-to-install-vnc-server-on-ubuntu-14.04</a>)</p>
  
  <p>i got the session and i am trying to connect to that via my vnc viewer but i see gray empty screen.
  how can i configure it in order to show normal desktop in the session?</p>
