The Trevilla it's a theme made for users που θέλουν στα Ubuntu τους να έχουν μια flat desktop with a minimalist mood.
The designers of Trevilla are not the only ones who use this simple look for a theme. In fact, more and more distributions come with flat work surfaces (and may be fashion from Windows 8).
Trevilla is one collection from flat subjects that follow a certain technique in aesthetics. The included themes are called White, Grey, Black and Chrome.
Η installation of the subject is really quite easy, especially with her help noobslab.com, a PPA is available for everyone. All you need to do is open a terminal and type the following commands (you must be in root to be able to run them correctly):
sudo add-apt-repository ppa: noobslab / themes
sudo add-apt-repository ppa: noobslab / icons
sudo apt-get update
sudo apt-get install trevilla-themes
sudo apt-get install trevilla-icons
To enable the issue, you should use a tool like Ubuntu Tweak, and note that this is not a matter for Ubuntu. It will also work with Linux Mint 17 "Qiana" and the procedure installation is the same.
