Wasn't clear to me on lightdm - since the light-locker docs/announcements talk about it "relying on lightdm" for the actual locking.

My setup - 4 monitors, nvidia, each with separate screen. If I lock screen and then control-alt-f7 back to X, only one single screen is protected. After several seconds, it forces a switch to the lock display, but in the mean time, the other three screens are COMPLETELY UNPROTECTED. It only takes a few seconds to launch a terminal and killall light- locker and I have unrestricted access to all.
