Adapta is one of the most popular GTK themes available for Linux — yet we’ve never written about it.
Not even once.
So, inspired by the screenshots you posted in our ‘Show Us Your Ubuntu Desktop‘ thread, I felt it was to time to give the Adapta theme a little OMG! love.
Adapta GTK Theme
The Adapta GTK theme is heavily inspired by Google’s Material Design language. If you’re not a fan of this shadow-heavy look then you probably won’t be a fan of this theme either as they’re very closely intwined.
Adapta is totally open-source GTK theme designed for modern GTK3-based desktop environments like GNOME Shell, Budgie and MATE. The theme itself is available in two distinct versions (similar to the Arc GTK theme): regular Adapta, and a half-dark/half-light Adapta-Nokto variant.
If you’re going to use this theme you don’t need to worry about which you use as they look identical, but you will notice a difference in Cinnamon, GNOME Shell and Budgie.
Install Adapta GTK Theme on Ubuntu
To install the Adapta GTK theme on Ubuntu run this command:
sudo apt-add-repository ppa:tista/adapta
sudo apt-get install adapta-gtk-theme
Once the Adapta theme is installed you can use a tool like GNOME Tweaks to change GTK theme on Ubuntu 18.04 LTS or later. Use the Unity Tweak tool, available in Ubuntu Software, for Ubuntu 16.04 LTS or earlier.
