Although in Gnome desktop I have set UHD resolution, GDM always switches to FHD - which results is visible switching and blurry display of the login screen, it’s really annoying
Another point is, even when I choose to use to use single external screen, GDM always shows an extended display on both and when my laptop lid is closed I can only login “blind” because it’s on the wrong screen.
