My readomatic directed me to a post by Anurag Arora, in which he gives detailed instructions on how to install several Ubuntu themes by Francois Vogelweith. Since Mr. Vogelweith himself writes in French, these English-language instructions are invaluable.
There is one spot in the instructions which might confuse the unwary, though. In the line
sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 0×1781bd45c4c3275a34bb6aec6e871c4a881574de
you need two hyphens before the words “recv” and “keyserver” (first occurrence). This isn’t necessarily obvious when reading the small font the line is written in.
These themes are well worth the effort of adding the extra repository. The files are large, but that’s because they contain a lot of extras you often don’t get in a theme download. For example, each theme comes with its own set of icons (though they’re mostly similar except for the colors). They also come with matching desktop backgrounds and GDM (login screen) themes.
I tried a few of these themes before settling on Balanzan (screenshot below):
Balanzan fits in well with the standard Ubuntu color scheme. That means if you don’t like the icons that come with the theme, it will work well with the default Human icons as well. I haven’t had that problem, but I can tell that the alternate icons may not fit everyone’s taste.
Two of the other themes, Bamboo Zen and Aquadreams, look like they would make good themes for Linux Mint if I ever get around to messing around with the new version (Linux Mint 7 Gloria).
