Starting with GNOME 3.0, for storing system settings uses the GSettings framework, based on the file format dconf. GSettings is used to store environment settings and applications and track their changes. For the user and the applications they are represented as a single “tree” of options, like the Windows registry. In addition, GSettings allows system administrators to limit the change of those or other settings, making them mandatory for users.
dconf is a low-level configuration system, the configuration system is based on keys, which stores the settings for most applications. The configuration keys are in the unstructured database (keys are logically interconnected grouped into categories), the key database is stored in a binary file located:
This file is created when you create the new user profile and dynamically changing in the process. In most cases, users do not need to manually edit the settings stored in dconf. Most settings are stored in the configuration file when you configure appropriate applications and tools (panels, panel applets, file Manager, etc). But sometimes the only way to change the key value is its direct editing, this is the most simple to implement and using dconf-editor.
Dconf–editor is the most commonly used graphic editing application dconf keys. In the application all the keys are presented in a tree view, you can look for clues by their title, bold text highlights the key importance which had been changed.
Using dconf-editor, you can get quick access to tons of hidden settings, system and appearance, allowing you to quickly make the system comfortable and convenient working environment.
With the help of search you can find the necessary settings and change them, but be careful with the changes. Not apply harm to your computer. Use the advice in paragraph 10 from article
