Package: xfce4 Version: 4.12.3 My screen gets locked requiring username/password authentication to unlock after some time even when screensaver is disabled and I see nothing to configure it from locking.
After some research I see locking is now handled by light-locker, but it seems the UI to change its settings (light-locker-settings) is not available on my installation of XFCE. Running testing (stretch). Please, reassign as necessary.
