Where is list of Gnome Startup Applications stored?
 

I have a script file which uses xrandr to configure and arrange 3 monitors. In order to run this when the user logs into a graphical (Gnome) session I reference it from the gnome desktop menu: SystemTab --> Preferences --> Startup Applications.
This works ok, so my question is this: Is this set of startup applications kept in a file (something like a graphical version of .bashrc)?
I would like to know as it would be useful for my documentation.
(I am running gnome on RHEL 6.5 with user being auto logged in)

Have a look in
