I have a fresh 16.04 install, and try to customize it a bit.
I got a few themes in
/usr/share/themes, but they are not listed in Unity Tweak. So I cannot try them.
Why is that ? How can I use them ?
They were already in that folder right after the installation, I only downloaded "Aurora". As you can see on the picture, I can only access "Ambiance", "Highcontrast" and "Radiance".
Thanks for the help
