I'm not sure if this is related or not but I am also having this issue in Lubuntu without xfce-power-manager being installed. I have disabled light locker and xset reports Standby: 0 Suspend: 0 Off: 0. I'm actually running Lubuntu on an older Intel iMac and when the screen goes off, any running apps also go off similar to Stavros.
