-=== GNOME desktop integration ===
-Using the following example configuration, QT applications will have a look similar to the [[GNOME]] desktop, using a dark theme.
-<syntaxhighlight lang="nix">
-qt = {
-  enable = true;
-  platformTheme = "gnome";
-  style = "adwaita-dark";
-};
-</syntaxhighlight>
-For other themes, you may need the packages <code>libsForQt5.qt5ct</code> and <code>libsForQt5.qtstyleplugin-kvantum</code> and a symlink from <code>~/.config/Kvantum/</code> to your theme package. Here is an example using Arc-Dark and [[Home Manager]]. In the Home Manager configuration:
-<syntaxhighlight lang="nix">
-qt = {
-  enable = true;
-  platformTheme = "qtct";
-  style = "kvantum";
-};
-xdg.configFile = {
-  "Kvantum/ArcDark".source = "${pkgs.arc-kde-theme}/share/Kvantum/ArcDark";
-  "Kvantum/kvantum.kvconfig".text = "[General]\ntheme=ArcDark";
-};

+To allow <code>powerdevil</code> (and by extension the "Brightness and Color" status tray menu) to control brightness on supported monitors directly instead of adjusting gamma, [[Backlight#Via ddcutil|configure your system to enable ddcutil]], and allow your user to use DDC/CI without root.

 Now one might not want to commit each and every change during development to iterate more quickly, but to just rebuild after having saved the latest changes.
