I had a very superficial look at debian/rules
override_dh_installsystemd:
dh_installsystemd -plightdm --no-start -r lightdm.service
I suppose you don't want that.
For one, it would unconditionally enable the service, not respecting the
debconf choice.
It would also unconditionally remove the display-manager.service symlink
on purge.
An empty
override_dh_installsystemd:
is probably better suited in this case.
Not sure if this fixes the issue you are seeing, just something I
noticed while quickly glancing at it.
