Update - I am looking for additional collaborators and maintainers to help me out with this. I have been keeping busy lately, and have been using Ubuntu sporadically, so it would be nice to have some help!


This is a Flat theme for Ubuntu and other debian based Linux Systems. This is based on the Ultra-Flat theme. Special thanks to @steftrikia and Satyajit Sahoo for the original work.



Install it manually, if you are on Ubuntu 16.04 or higher. If you prefer the .deb installers, please download the correct one, based on the version from here.

This theme was designed specially for the Unity environment on Ubuntu as I have only tested it on Ubuntu. It might not work properly for the other versions.

To install the theme, you must first install the Unity Tweak Tool. It can be installed by simply running the command:

sudo apt-get install unity-tweak-tool


If you are on Ubuntu 16.04 or higher, run the commands below to install Ubuntu Tweak:

wget -q -O - | sudo apt-key add -
sudo sh -c 'echo "deb xenial-getdeb apps" >> /etc/apt/sources.list.d/getdeb.list'
sudo apt-get update
sudo apt-get install ubuntu-tweak

or head over to their website, downloading the .deb file (recommended).

1. Using the .deb file for Debian, Ubuntu and derivatives (Recommended)

Download the .deb file from here, double click to open with Ubuntu Software Center and click on install. Then, install the theme using ubuntu-tweak.

2. Using the noobslab PPA

sudo add-apt-repository ppa:noobslab/themes
sudo apt-get update
sudo apt-get install flatabulous-theme

3. Manually

Download the source to the theme here. If a problem occurs with your installation, kindly download the correct version based on your version of Ubuntu from here. If you are a developer or a designer, I also encourage you to contribute to it. Create a folder, called .theme in your home directory. This can be simply created by firing up your terminal, and then running

mkdir .themes

Now this is a hidden directory, to view this in Nautilus, you can press Ctrl/⌘ + H. Alternatively, you can also place the extracted files in your /usr/share/themes/ folder.

Flat Icons

Flat Icons Dashboard

For icons, I use the ultra-flat-icons theme. It is available in blue (recommended), orange and mint green colors. To install this, you can run the following commands

sudo add-apt-repository ppa:noobslab/icons
sudo apt-get update
sudo apt-get install ultra-flat-icons

Alternatively, you could also run sudo apt-get install ultra-flat-icons-orange OR sudo apt-get install ultra-flat-icons-green.

based on you color preference. I recommend these flat icons, but you can also look at Numix and Flattr.

Now press your super key, search for Ubuntu Tweak and fire it. Under the tweaks tab, there is an option for theme. Under that select the Flatabulous theme. Under the icon settings, select ultra-flat-icons. Restart your computer, and you should be good to go! You computer will look something like this after you restart.

Q. What are your terminal theme and settings ?

A. I am presently using zsh with oh-my-zsh configuration. For the colorscheme, I am using a modified version of the default tango colors, material colors and the one dark scheme.

My zsh config can be found here. This works if you have powerline fonts installed and oh-my-zsh setup. All other dotfiles can be found here.

Here is a script that will add a new profile in gnome-terminal that mimics my terminal settings.

A one liner install can be done by running the command
