gnome-session-bin - 46.0-3 main

The GNOME Session Manager is in charge of starting the core components
of the GNOME desktop, and applications that should be launched at
login time. It also features a way to save and restore currently
running applications.
.
This package contains the binaries for the GNOME Session Manager, but
no startup scripts. It is meant for those willing to start
gnome-session by hand with the components of their choice, and for
applications such as GDM that use gnome-session internally.
