The problem seems to be /usr/lib/lxdm/lxdm-greeter-gtk crashing at g_key_file_load_from_file(). Also, lxappearance crashes similarly. This may be related: https://gitlab.gnome.org/GNOME/glib/-/issues/2361 . But the crash seems to be triggered by plasma.desktop and twm.desktop in /usr/share/xsessions. In both of those, the Name[whatever]= and Comment[whatever]= lines cause the crash. Yet xfce.desktop works with such lines.
/usr/lib/lxdm/lxdm-greeter-gdk does work but seems lacking in features.
