How do I apply a 200% scale factor to the login screen in Zorin OS 18?

Hello,
Since I started using Linux, I've noticed that everything is too small on the login screen. Once logged in, I configured the desktop with a scale factor of 200%, but I would like to apply this setting to the login screen as well, right from startup.

For your information, I am now on Zorin OS 18 and my screen is a 4K TV.

How can I do this, please?

I'm not sure but you could try it with gdm-settings. Follow the guide for ubuntu 24.04.

You can set a scaling factor for the font at the login screen and at tab display you can set "Apply the current screen settings"

I tried it on the Zorin 18 live boot stick. The first method didn't work for me, only the second one with adding the ppa. But I couldn't test it with the loginscreen.
I also tried the flatpak of gdm-settings which worked to install.

Glad to hear that it worked!

GDM Settings did work for You? Which Version?

For People who that not work a little Tipp to get it done:

  1. Set up the Display Settings in Settings>Displays
  2. Then open the Terminal and type sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config/
