Customizing the Login Screen

The login screen is the first thing you see when you start your Fedora Linux system. You can customize the login screen to match your system’s theme or personal preferences.

Using the Gnome Tweaks Tool

The Gnome Tweaks Tool is a powerful utility that provides advanced customization options for the GNOME desktop environment. It allows you to tweak various aspects of your desktop, including the appearance, behavior, and functionality.

1. Install the “Gnome Tweaks” package from the Software application or your preferred package manager.
2. Once installed, open the “Tweaks” application (you can search for it in the “Activities” overview).
3. The Tweaks application is divided into several sections, each offering different customization options:
   • “Appearance”: Customize the desktop theme, icons, cursors, and more.

If you’ve made too many customizations and want to revert to the default system theme and settings, you can easily do so by following these steps:

1. Open the “Settings” application and navigate to “Appearance”.
