Autostart programs and scripts in ubuntu
There is a GUI for that (tested by me). Just find the autostart GUI application through your application launcher. You can also edit directly the desktop files that are constructed in ~/.config/autostart . Keep in mind though that the GUI decides the names there so if you need to find and edit a specific statup you may need to look around a bit!
