In contrast the previous release of Ubuntu 11.10 and Linux Mint 12 we have no tools to change the icons, but we can change the default theme from the Background section on System Settings.
Thanks to our reader's suggestion Today we're going to see how to change the theme and icons with Ubuntu Tweak.
The new version 0.6 of Ubuntu Tweak Among the many new features that have come also offers the possibility of change the default theme and icons on the new Gnome 3 with great ease.
First we download (I recommend it for GTK+ 3) Or new icons to be included in our distribution.
For this just copy the theme folder inside the folder .themes present in our home (just click to view Ctrl+h if there is not enough to create it) and copy the folder icons always in the folder .icons present in our home (just click to view Ctrl+h if there is not enough to create it)
At this point, just start Ubuntu Tweak and go to Tweaks and click Theme
In the window that opens we can change the theme with the new section of the GTK Theme and the set of icons in Icon Theme.
We close the window and here is the new theme or set of icons installed.
