The Clearlooks-Phénix project aims at creating a GTK3 port of Clearlooks, the default theme for Gnome 2. Style is also included for GTK2, Unity and for Metacity, Openbox and Xfwm4 window managers.

Here are screenshots (if applicable, click to see the original image):

  • Requirements for Clearlooks-Phénix v1: packages gtk2-engines (if GTK2 applications are used) and gnome-themes-standard.

  • Requirements for Clearlooks-Phénix v2: packages gtk2-engines (if GTK2 applications are used), gnome-themes-standard and gtk3-engines-unico.

  • Requirements for Clearlooks-Phénix v3 and newer: package gtk2-engines (if GTK2 applications are used).


  • Download the appropriate version according to your situation:

    To find your GTK version:

    • You can check in your package manager the version of the package libgtk-3-0.

    • If you use Ubuntu, here's a correspondence between its versions and those of GTK (for a default installation of Ubuntu):

      • Ubuntu 11.10: GTK 3.2
      • Ubuntu 12.04: GTK 3.4
      • Ubuntu 12.10 and 13.04: GTK 3.6
      • Ubuntu 13.10: GTK 3.8
      • Ubuntu 14.04: GTK 3.10
      • Ubuntu 14.10: GTK 3.12
      • Ubuntu 15.04: GTK 3.14
      • Ubuntu 15.10: GTK 3.16
      • Ubuntu 16.04: GTK 3.18
      • Ubuntu 16.10: GTK 3.20
  • Extract the archive.

  • Rename the extracted folder to Clearlooks-Phenix.

  • Copy the folder Clearlooks-Phenix in one of the following two locations:

    • ~/.themes/ for the current user;

    • /usr/share/themes/ for all users, including style for programs ran with root privileges (e.g. Synaptic).


The theme must be selected once the installation is complete:

  • On Gnome: with gnome-tweak-tool, by setting Theme > Window theme and Theme > GTK+ theme, or in a terminal:

      dconf write /org/gnome/desktop/wm/preferences/theme \'Clearlooks-Phenix\'
      dconf write /org/gnome/desktop/interface/gtk-theme \'Clearlooks-Phenix\'
  • On Xfce: by going to Settings > Appearence > Style in the main menu for the GTK theme, and to Settings > Window Manager > Style for the Xfwm4 theme, or in a terminal:

      xfconf-query -s Clearlooks-Phenix -c xfwm4 -p /general/theme
      xfconf-query -s Clearlooks-Phenix -c xsettings -p /Net/ThemeName


Desktop managed by Nautilus

By default, the font color on a desktop managed by Nautilus is black. To set it to white, open the file gtk-3.0/applications.css with a text editor, find the code relative to Nautilus:

 * Nautilus *


and uncomment it, as follows:

 * Nautilus *


To get a custom color, change the color directly in the file gtk-3.0/applications.css.

Window buttons layout

If after installing or updating Ubuntu, the window buttons are on the left side, but you want them to the right, run the following command in a terminal:

gconftool-2 --set /apps/metacity/general/button_layout --type string ":minimize,maximize,close"


The wallpaper used for the Gnome 3 desktop screenshot is available in the folder wallpapers.


The icon theme used for the same screenshot is Mist, installed with the package gnome-themes, under LGPL. However, this package is no longer available with last Ubuntu versions. Here's an easy way to install Mist:

  • Download the archive of the Mist icon theme.

  • Extract the archive.

  • Copy the folder usr/share/icons/Mist in one of the following two locations:

    • ~/.icons/ for the current user;

    • /usr/share/icons/ for all users.

  • Then, choose Mist:

    • on Gnome: with gnome-tweak-tool by setting Theme > Icon theme;

    • on Xfce: by going to Settings > Appearence > Icons in the main menu.
