...to start <command> on startup and to terminate the compositor when <command> exits. This is useful for session management as it allows the session client (for example `lxqt-session`) to terminate labwc - be exiting itself. Under X, xinit starts the server and keeps it alive for as long as lxqt-session runs. Thus either the session client starts the Window Manager, or the Window Manager can be launched independently first. On Wayland, the Compositor is both Display Server and Window Manager, so the described session management mechanisms do not work because the Compositor needs to be running before the session can function. As some session clients support both X11 and Wayland, this command line option avoids re-writes and fragmentation. Co-authored-by: @Consolatis
