The theme for desktop Atolm is a very popular dark theme, with an excellent finish. Let's see the steps to install Ubuntu.

Open a terminal from menu Applications -> Accessories -> Terminal or by pressing CTRL + ALT + T.

First of all remove all traces of the theme that we have owned previous versions installed. We use the following command:

rm -R ~/.themes/Atolm

We started installing install Equinox:

sudo add-apt-repository ppa:tiheum/equinox
sudo apt-get update && sudo apt-get -y install gtk2-engines-equinox

Install the icons awoken :

sudo add-apt-repository ppa:alecive/antigone
sudo apt-get update && sudo apt-get install awoken-icon-theme

Now install Atolm:

sudo add-apt-repository ppa:nikount/orta-desktop
sudo apt-get update && sudo apt-get -y install atolm-theme

And install the theme for the Emerald decorator if we use:

sudo apt-get install -y atolm-emerald-decorators

Now you have installed. We will activate the menu System -> Preferences -> Appearance. In the first tab is called Item can see all the themes installed on our Ubuntu. We look for the one named Atolm to activate.

I tried it on Ubuntu 4.10 Hardy Heron and Ubuntu 10.10 Maverick Meerkat and installs fine on both. The version at this time is 0.7.5.
