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.
