GTK themes need to be updated to work with each new major GTK version, and because of this, some beautiful themes available for GTK 3.2 or 3.4 like Zukitwo and others, don't work with the latest GTK 3.6 available in Ubuntu 12.10 and other Linux distributions.





There are, however, a few cool themes which work with the latest stable GNOME / GTK (3.6). Below you'll find 8 GTK3.6 compatible themes which are available in PPAs / repositories for Ubuntu 12.10 and work with both GNOME Shell and Unity.

Greybird, the default Xubuntu theme, includes a Xfwm4 theme obviously, as well as GTK3 and GTK2 themes, so it can be used in Unity or GNOME Shell too and not just in Xfce:

Ubuntu 12.10 users can install Greybird theme from the official Ubuntu repositories using the following command (the package contains some other themes, like Bluebird as well):

sudo apt-get install shimmer-themes

sudo add-apt-repository ppa:webupd8team/themes sudo apt-get update sudo apt-get install adwaita-x-dark-theme

sudo add-apt-repository ppa:webupd8team/themes sudo apt-get update sudo apt-get install adwaita-x-light-theme

For other Linux distributions, Adwaita X Dark/Light can be downloaded via Gnome-Look

Evolve is a minimal light theme that works with GTK 3.6 and includes a GTK2 theme as well as an Xfwm4 theme:

sudo add-apt-repository ppa:satyajit-happy/themes sudo apt-get update sudo apt-get install evolve-gtk-theme

Gnomish Beige is a beautiful, beige theme based on Adwaita. The pack comes with GTK2/3 (GTK 3.6 compatible) themes as well as a GNOME Shell theme:

To apply any GNOME theme, use GNOME Tweak Tool, Ubuntu Tweak, Unsettings or other such tools.





And a final, important note: in Ubuntu 12.10, there's an overlay-scrollbar bug which causes some themes to display black widget areas. The only way around this bug so far is to remove the "overlay-scrollbar" package.
