We have previously seen the manual installation of the Nitrux OS icon theme under Ubuntu. To make the installation of this icon theme easier, I have uploaded it to a custom PPA. The theme is compatible with both Ubuntu 12.10/12.04/11.10 (Unity & Gnome Shell) and Linux Mint 13 Maya.
Nitrux OS is available in three versions, you can enable them as described below. Here is a screenshot of the theme under Ubuntu Unity:
Nitrux OS Installation
Open the terminal and run the following commands to install Nitrux OS (1.8b):
sudo add-apt-repository ppa:upubuntu-com/themes
sudo apt-get update
sudo apt-get install nitruxos
You can enable the default version of NitruxOS with this command:
gsettings set org.gnome.desktop.interface icon-theme 'NITRUX'
You can enable the other versions of NITRUX using Gnome Tweak Tool or MyUnity.
