Recently I am trying to use Xubuntu on my low-end laptop. There is a problem, obviously, for VNC connections.
Here are some related web-pages. I am trying to find a startup script for x11vnc now.

Then I mixed the findings from http://askubuntu.com/questions/459277/how-do-i-make-a-program-auto-start-everytime-i-log-in-in-ubuntu-14-04 and http://forum.lxde.org/viewtopic.php?f=3&t=31114 then created X11VNC.desktop at home/.config/autostart the contents of the desktop file is (Autostart is a wrong directory name the correct one will be autostart)
