> Bear in mind this is for a JWM desktop with no LXDE or Openbox sessions running or installed.
Obsession is not really Openbox related, it's mostly a tool to manage Systemd, Upower and ConsoleKit session commands with graphic or console interface. Maybe I should have named it suc-session (for Systemd, Upower and ConsoleKit).
The GUI version also manage the switch user thing provided by the xDM family (LXDM, GDM, KDM, LightDM).
Obsession also brings a modern way to autostart programs with xdg-autostart.
All of these tools can be used with other windows managers that don't have session management .
