Binary package “cinnamon-session” in ubuntu kinetic

Cinnamon Session Manager - Minimal runtime

 The Cinnamon Session Manager is in charge of starting the core components
 of the Cinnamon 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 Cinnamon Session Manager, but
 no startup scripts. It is meant for those willing to start
 cinnamon-session by hand with the components of their choice, and for
 applications such as MDM that use cinnamon-session internally.
