You can also use Dconf Editor to make typical system changes if you can’t use the command Terminal app.

If you are familiar with Windows, you know about Windows Registry Editor.

Ubuntu Linux doesn’t have a registry database to configure hidden system settings. Howerver, Ubuntu Linux uses the Dconf Editor tool to change low-level system configurations and settings.

You can call it a Ubuntu Linux Registry Editor because it provides similar functionality without a massive Windows system database.

To use Dconf Editor, you must first install it since it doesn’t come with Ubuntu Linux.
