For them to work, and if you want to be able to unlock your screen ;-), you need to make sure you use ‘screen-locker-service’ for each of them. So: (operating-system ;; … (services (cons (screen-locker-service xscreensaver) %desktop-services))) since ‘%desktop-services’ already takes care of slock and xlock. Could you try and report back? We’re getting there! :-) Ludo’.
