It is the gnome-session-properties command.
I know already the apps are at ~/.config/autostart.
I know there are files at /etc but those are root.
I found nothing at gconf-editor.
I need to know where gnome-session-properties stores what apps are disabled and enabled to auto startup, so I can backup that file.
If you edit the files inside ~/.config/autostart/ they are written in this way:
[Desktop Entry]
Name=Dropbox
GenericName=File Synchronizer
Comment=Sync your files across computers and to the web
Exec=dropbox start -i
Hidden=false
Terminal=false
Type=Application
Icon=dropbox
Categories=Network;FileTransfer;
StartupNotify=false
X-GNOME-Autostart-enabled=false
The last line is the one that specifies if the app is enabled or not (check it by yourself with the gnome-session-properties enabling and disabling an app and noticing the change of that option in the file).
Then, you only have to copy all the files inside the folder to make a backup of that configuration.
