I tried Alf’s workaround on a laptop on which Debian buster with an Xfce desktop was installed recently. I use this laptop, a Thinpad X220, mainly docked, alternating between one docking station with two external screens (display port + DVI) and one with a single external screen (DVI). When docked to the station with two screens most issues with light-locker have disappeared. Still, at one occasion there was a black screen after wakeup from suspend-to-RAM, and I had to kill light-locker form a text VT. But when docked to the other station (with one screen), lightdm does not show any user interface elements. The Debian background image is visible, but neither the window where the username/password is to be entered, nor the UI elements at the top right of the screen. Still, I can log in blindly. When locking the session, the same problem reappears. The greeter reappears again when I remove the file /etc/X11/xorg.conf that was created for the workaround. By the way, I ran “X -configure” also when docked to the station with the single screen and the resulting xorg.conf file is identical to the one that was generated at the other station.
