This is just a quick find and replace command that changes the NoDisplay=false with NoDisplay=true in all the programs that are in autostart. Once you do this, open Startup Applications and you shall see many more programs here:
sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop
sudo sed -i 's/Hidden=true/Hidden=false/g' /etc/xdg/autostart/*.desktop
sed -i 's/NoDisplay=true/NoDisplay=false/g' ~/.config/autostart/*.desktop
sed -i 's/Hidden=true/Hidden=false/g' ~/.config/autostart/*.desktopReferences:
