To install Ambiance-Lime theme on Ubuntu/Linux Mint open Terminal (Press Ctrl+Alt+T) and copy the following commands in the Terminal:
Other theme to be installed are:
sudo apt-get install ambiance-black-panther
sudo apt-get install ambiance-blue-broken
sudo apt-get install ambiance-dark
sudo apt-get install ambiance-ds-blue
For more themes use Synaptic and select this ppa as origin to see more installable themes.
to select these themes, use Myunity instead of the standard theme selector, because this one won't recogknize the new themes for one obscure reason.
Change the default theme of new usersThe default Ubuntu theme for new users in Ubuntu is the Ambance theme. I don't like it and want something completely different. That's easily done this way:
Place the gnome config files into a folder called /etc/skel, any new user you create will have those files in their home folder.
though I'd add the folder you want to put in /etc/skel is .gconf
And you should make your installed theme available in /usr/share/themes and icon theme in /usr/share/icons.
This should work.
Another way of installing different themes for Ubuntu 12.04 and newer is found at the ZonColor Themes.
ZonColor by Zon Saja is a set of 16 themes (though not all can be used in Unity), 21 icon theme variants (mostly different coloured folders), and some matching wallpapers. This wide range of simple, well-made components allows you to mix-and-match different elements until you come up with something you like.
The GTK3 themes themselves cover a wide range of styles – from the Ambiance-like ‘Audience‘ and ‘ZonColor Hard‘ themes to the striking colours of ‘Birdycloud’ and ‘Zoncolor’.
Once you’ve chosen a theme you can set an icon set to match it. Again, these vary from the colourful and flat, to the glossy and shiny.
To install Zoncolor theme pack in Ubuntu you’ll first need to grab the latest release from its official homepage.
Once the Zoncolour archive has fully downloaded you’ll need to ‘unzip’ it. In Ubuntu this is as simple as right-clicking on the archive icon, and selecting ‘extract here’ from the menu that appears.
After extraction enter the folder and run the ‘install.sh’ file inside by double-clicking on it. If you don’t see a prompt appear you may need right click on the install.sh file, go to Properties > Permissions, and check the box next to ‘allow executing file as programme’. Double click on the file and choose to run it from within a terminal. When you launced the programm you can choose whether you only want the theme, or want the ‘zoncolour’ app installed too (the app allows you to apply customizations to each theme). I choose ‘Install themes only’.
Once the installer has done its bit, it’s over to you. To switch between/set themes/icons you’ll need to use a third-party app like Unity Tweak Tool or UNsettings or Ubuntu tweak. The theme selector thats build in Ubuntu won't work.
Ubuntu 13.04 users install it from the Ubuntu Software Center:
Ubuntu 12.10 or 12.04 users will need to use another tool thats found in the Software Center, like Unsettings. or Ubuntu Tweak
Sometimes Unity doesn't apply the new settings at once. So please logout and login again to have all effects visible.
