Hi,
during tests with piuparts I noticed the same behavior in 4 packages
providing a display-manager service: a dangling symlink is left after
purge. Some have individual bugs filed (lightdm: #775385, gdm3:
#771085), but this is more likely a bug somewhere in the helpers being
used. Notice, that after purge no other package providing a
display-manager service was installed any more.

Hey,
sddm handles the dangling symlink since 0.14.0-2. The puiparts logs also don't
show any traces that this symlink is dangling. Unfortunately Andreas Beckmann
did not add any notice why they reopened this bugreport.
Let's close this bug report for the oldest version where I can see puipart
logs.
The relevant part of postrm file, that handles the symlink:
DEFAULT_DISPLAY_MANAGER_FILE=/etc/X11/default-display-manager
DEFAULT_SERVICE=/etc/systemd/system/display-manager.service
case "$1" in
purge)
[...]
if [ ! -e "$DEFAULT_DISPLAY_MANAGER_FILE" ] &&
[ -h "$DEFAULT_SERVICE" ] && [ ! -e "$DEFAULT_SERVICE" ]; then
# Dangling symlink, no other display-manager installed
rm "$DEFAULT_SERVICE"
fi
;;
Best regards,
