The daemon could keep track of how many monitors are connected and exit when the count drops to zero (after waiting some small amount of time for a new monitor connection which also handles the initial startup case). This daemon isn't queuing right? So we define that when there is no monitor connected, all events are dropped. > c1 starts up, simply sends events as it does not to "\0$lxcpath".
