We regularly share GTK themes for you to use on your Ubuntu desktop but we’ve never taken the time to show you how to change theme on Ubuntu specifically.

This post corrects that, though I won’t lie: it is so easy to change theme on Ubuntu that not much of a blog post is required to walk you through it 😉.

But just incase you (or someone you know) needs a hand, here follows a simple guide, perfect for beginners or those new to Ubuntu.

How to Change Ubuntu Theme

If you’re reading this tutorial from a machine running Ubuntu 18.04 LTS (or above) then honestly: this walkthrough couldn’t be any easier.

To swap, switch or change Ubuntu theme all you need to do is:

  1. Install GNOME Tweaks
  2. Open GNOME Tweaks
  3. Select ‘Appearance’ in the sidebar of GNOME Tweaks
  4. In the ‘Themes’ section click the drop down menu
  5. Pick a new theme from the list of available ones

I’ll now walk you through these steps in a bit more detail.

First up you need to install GNOME Tweaks in Ubuntu. To do this you can smush the button below and hit ‘Install’ in the window that appears or open Ubuntu Software and manually search for ‘GNOME Tweaks’ by typing it in the search box:

Install GNOME Tweaks on Ubuntu

If you prefer to add/remove software using a terminal you can install GNOME Tweaks from the command line by issuing this command:

sudo apt install gnome-tweaks

Whichever way you install the utility once you’ve it, open it. You can do this by searching for ‘GNOME tweaks’ in the applications screen or running gnome-tweaks in a terminal session.

in the GNOME Tweaks window select the ‘Appearance’ section in the left-hand sidebar (see the screenshot above).

Next, find the “Theme” sub-heading and click the dropdown menu beside ‘applications’ to see a list of available GTK theme.

By default, there aren’t many different themes to choose from. For more choice why not install something from our list of the best GTK themes? The Qogir theme is pretty popular, as are other themes made by Vinceliuice.

The theme change takes effect instantly, letting you preview the new look. If you’re happy with what you see you can close the app. Otherwise, pick another theme, etc.

Simple once you know how, isn’t it?
