Linux is awesome. It has open code and is community driven and versatile. And, best of all, it’s customizable. You can take it apart, swap things around and make it your own.
One particular type of customization that stands out the most are GUI themes (and in this case GTK themes). Theming your desktop environment does a lot. It can make your desktop a refreshed and completely different experience.
How to install GTK Themes
There are two different ways to install GTK themes. You can install the theme to the root theme directory which will make your new theme available to all users on the system. Alternatively, it’s possible to just install the theme to your home directory for your own use.
For example: If you wanted to install the Iris Dark theme, you’d go to the download page and get the theme’s .zip file. Once you have it downloaded, extract it, move the folder to your home directory and open a terminal window.
Installing GTK theme system wide
sudo mv ~/gtk-theme-folder/ /usr/share/themes/ -r
Installing GTK theme for one user
mv ~/gtk-theme-folder/ ~/.themes -r
Note: The .themes folder is hidden by default. If it does not exist, create it.
Once your theme is installed, you can go to the System Settings to change the theme.

Do you have a favorite GTK theme to suggest? Tell us in the comments!

One of the first things I used to do when I install Mint on a new system (after all the updates, of course) is download the themes – there’s heaps of them! Now, I’m a bit more selective, with just a few favourites: SmoothPurple, Tyr Himinn, Void and nightfall, with SmoothPurple usually the one that gets used. Unfortunately, a theme by itself doesn’t necessarily install the icons or windows borders I like, which I get from Synaptic (type “themes”) in the search thing. I favour HeliX-Sweetpill-Crowberry for borders and Nuovo for icons, although the nuvola and oxygen icons are really nice too.
