"Seek and Ye Shall Find"
Just a quick update - after posting my last post, I decided to spend 10 minutes trying to theme 12.04 (Unity) to something more aligned to my tastes. The result:
Set the selection color to "steel blue":
Then to change the icon theme:
gsettings set org.gnome.desktop.interface gtk-color-scheme 'selected_bg_color:#63B8FF;'
sudo apt-get install myunity
1. Ran MyUnity.
2. Clicked on the "Themes" tab.
3. Selected the Oxygen theme.
Now my desktop environment is better suited to my tastes .
If you want to install the blue Elementary theme:
And then run MyUnity again and select the Elementary Icon theme.
sudo apt-get install elementary-icon-theme
I also found a bunch of cool icon themes in another repo:
Then you can install, for example, the Linux Mint theme using:
sudo add-apt-repository ppa:webupd8team/themes
sudo apt-get update
(and then start MyUnity and select the Mint icons under the "Themes" tab).
sudo apt-get install sudo apt-get install mint-x-icons
gsettings set org.gnome.desktop.interface gtk-color-scheme 'selected_bg_color:#4e9a06;'
So it looks like Ubuntu 12.04 is customizable. I'd still like to see something to make it easier to switch themes (something where you don't have to install PPAs and the like). Strange that such beautiful icon sets are hidden away and can only be installed by "those in the know".
