Public bug reported:
The greeter does not respect users' HiDPI preferences, leaving the
greeter at default scale while the desktop session scales accordingly.
Ubuntu MATE 20.10
Monitor resolution and size:
3840x2160 - 28" (This is not necessarily ideal for HiDPI and does not
automatically trigger scaling. Thus, a manual toggle to force scaling is
needed, which only seems to affect the desktop session.)
