Josselin sent this message intended for the thread and I think they are okay with re-pasting here,

I don't really think this is a bug per-se, as > running without elogind is advanced stuff and its consequences should be > understood by the user. I support any conclusion from Josselin and unmatched-paren and want to add these observations, * wlgreet *does require* the greeter lock file * wlgreet *does not require* elogind/logind * not-advanced users like me may want to use wlgreet without elogind
