Numix - GTK3 theme by ~satya164 ( Suggested by UltimateDesktops and Featured by neiio )

The theme is a bit unusable on Ubuntu 14.04 LTS with Unity.

Issue 1: The theme cannot be changed using System settings ->Appearance -> Theme.
             Because it doesn't appear there.

So I installed Ubuntu tweak tool to change the theme and I got a whole different issue.

Issue 2: After changing to Numix theme, the boxes around the icons on unity launcher disappear(along with animations). The only way to fix this is by going to System settings ->Appearance -> Theme. When I get there, the default selection of theme drop down box is empty. After I change it to 'Ambiance' or any other default theme, the boxes around those icons reappear and icon animations start to work again.

Please let me know if you want me to include any screenshots. I'd be happy to provide them.

About Issue 1, Ambiance and Radiance are hardcoded to the settings  and we cannot add new entries.

Issue 2, it's a design decision to remove the boxes in the launcher, not a bug.

I purchased this theme so that I could use the Dark Flat Numix. I am using Ubuntu 12.04, and I extracted the dark theme to /usr/share/themes as instructed and set it with the terminal commands also listed in the help. Instead of black, everything becomes gray and squarish like on windows 95. I believe something is wrong with it. I tried setting the permissions on the theme folder so that I could set the theme using unity-tweak, which also made the same effect. Can I please have some help with getting my theme working? Thanks.

Also, the regular numix theme, which I installed via ppa is working fine. It's just the dark theme. Also, is there a difference between dark flat and regular dark? I would have purchased the dark flat if I had found it first on the ubuntu software center.

Did you use the version for GTK3.4?

Get in touch with me on and we'll try to solve the issue.

Awesome theme. But hey could you tell me the name of the font used in the numix logo. The one on this page :…
satya164 Featured By Owner Jul 6, 2014  Hobbyist General Artist
It's custom drawn. No font used.

Okay. Awesome theme by the way. Love the Nimux Circle icons too :)

Hi, I'm using Numix Flat Dark (purchased) + Numix Circle and my Unity launcher icon refuses to switch to the Numix provided icon.…
satya164 Featured By Owner Jul 5, 2014  Hobbyist General Artist
You have to replace the launcher icon manually. Unity doesn't support replacing it.
cassocks Featured By Owner Jul 5, 2014
Could you walk me through the process of doing that? I can't even find the launcher icon in usr/share/icons
