I always use Accessiblity setting > Seeing > Large Text on my monitors. This setting works after logon to Gnome shell version 50.1. It has also worked previously on the startup login screen, but not lately where the login screen/menu comes with smaller, default text/size each time.
Is there some special setting now for the login screen to be saved?
AI search mentions “copy your user font preferences into the system-wide GDM profile or Alternative: Global UI Display Scaling”. None of these has been required previously.
Yeah this is probably fallout from changes in gnome-shell / gdm, as you have found out.
That said, filing a bug would not hurt, as we have “work todo” in gdm (remove the static gdm system user) as it is now dynamically created since gdm 49.
