Startup Applications does not show all applications

Show all items in the folder /etc/xdg/autostart/ to be able to enable en disable then in the Startup Manager. You might need to repeat this after installing new appliciations.

sudo sed --in-place 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop

Now you can configure what applications are started automatically when you startup.

gnome-session-properties
