Despite the options in NixOS versions before 25.11 being under the <code>xserver</code> module, GNOME uses [[Wayland]] by default. NixOS 25.11 and later removes support for the [[Xorg]] session entirely (though Xwayland is still included and supported for compatibility).

If you wish to discover the corresponding dconf entry for a given setting in a program, you can run `dconf watch /` inside of a terminal and change the setting graphically. For example, when changing toggling the Quick-Settings option "Dark Style" from "on" to "off" and back to "on," this will be the output:<syntaxhighlight lang="shell-session">
