It appears what's going on (in my observed case, at least) is that the
xfce4 package depends on xfce4-session, which pulls in light-locker as a
Recommends, which in turn pulls in lightdm as a dependency. And when
Xfce searches for a screen locker to use, it seems to discover light-
locker first and
After installing the xfce4 packages in Ubuntu 20.04 and starting a xfce4
session from the default bootup login screen, I immediately get a
similar crash notification. If I launch light-locker from a terminal, I
