Light Locker - Run script on screen lock/unlock I'd like to run a script if the XFCE session is locked and unlocked. Is there a way that I can intercept this and perform certain actions when the desktop is locked or unlocked? I have found following solutions: for Gnome - Run script on screen lock/unlock for `xscreensaver` \- How do I run a script on unlock? But I'm using `light-locker` and no screen saver. I was trying to monitor DBUS but it doesn't seem the `light-locker` emits any signals. One option would be to modify `xflock4` but that would help only with screen locking. Is there any way for `light-locker`?

The previous answer helped me write this fragment of bash script that handles Lock and Unlock session events for the current session. I use it to suspend browser processes when the session is locked and to resume them when it unlocks. Tested under Debian unstable (Xfce 4.12) Enjoy!

dbus-monitor --system "type=signal,path=$session,interface=$iface" 2>/dev/null |
while read signal stamp sender arrow dest rest; do
case "$rest" in
*Lock)
echo LOCKED at $stamp
pause $@
;;
*Unlock)
echo UNLOCKED at $stamp
resume $@
;; #unknown Session signal received
*)
# echo $signal $stamp $sender $arrow $dest $rest
esac
done
