Based in Numix

A modern flat theme with dark elements. It supports GNOME, Unity, Xfce and Openbox.


Build It

First, you need to compile the theme using the Sass compiler.

To install Sass, install Ruby and the gem command using your distribution's package manager. Then install sass with the gem command,

gem install sass (not needed for Ubuntu/Debian)

You'll also need the glib-compile-schemas and gdk-pixbuf-pixdata commands in your path to generate the gresource binary. Install them using your distribution's package manager.

Distro Commands
hyperbola  parabola  arch sudo pacman -S ruby glib2 gdk-pixbuf2
opensuse sudo zypper install glib2-devel gdk-pixbuf-devel
fedora sudo dnf install glib2-devel gdk-pixbuf2-devel
trisquel  debian  ubuntu sudo apt-get install ruby-sass libglib2.0-dev libgdk-pixbuf2.0-dev libxml2-utils

After installing all the dependencies, change to the cloned directory and, run the following in Terminal,

make zip

or for install in global system:

sudo make install

To set the theme in GNOME, run the following commands in Terminal,

gsettings set org.gnome.desktop.interface gtk-theme "Librix"
gsettings set org.gnome.desktop.wm.preferences theme "Librix"

To set the theme in Xfce, run the following commands in Terminal,

xfconf-query -c xsettings -p /Net/ThemeName -s "Librix"
xfconf-query -c xfwm4 -p /general/theme -s "Librix"

In Openbox you can set the theme with ObConf tool. Alternatively, you can set the theme by changing the <name>key value to Librix in the <theme> section of your rc.xml file.

For developers

If you want to hack on the theme, make sure you have the inotifywait command available, which is used for watching and automatically building the files.

To start watching for changes, run the following,

make watch

If you change any assets, you'll need to regenerate the gtk.gresource.xml and gtk.gresource files. You can use grrr to do it easily.
