TrialnError [1] filed a deletion request for gnome-settings- daemon-120dpi [2]: To quote the latest comment on this package from the orphaned + OOD list: "I am getting very good results in 3.20 by just using the scaling option in gnome tweak tool. It seems we can could away without this hack now." And as no one is maintaing it it seems this is general consens.
