Description:
GNOME Session Manager - Minimal runtime
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.
