Source: kerneloops Version: 0.12+git20140509-6 Ubuntu still includes the Startup Applications app in the default install (it was dropped in gnome-session upstream years ago).
To prevent users from being able to easily disable system services that they probably shouldn't, Ubuntu makes sure that apps included by default set NoDisplay=true in their autostart files. This hides the services from the Startup Applications app. By the way, MATE has a similar tool but it doesn't respect NoDisplay yet. https://github.com/mate-desktop/mate-session-manager/issues/134 Thanks, Jeremy Bicha
