Installing fonts on Ubuntu 9.10
Ubuntu comes with a large selection of fonts pre-installed, with many more available from the package repositories. If you want to use a font that isn't in the repositories then, provided it's a TrueType font, you can install it manually.
First, check that your fonts are TrueType. This information should be available when you download the font. TrueType fonts normally have the ".ttf" file extension and will usually show a thumbnail preview on Ubuntu.
To install the font start by opening a file browser and ensuring that it is set to display hidden files, Next, navigate to your home directory. Check if you already have a directory called ".fonts". If you don't then you will need to create one.
You can now copy the fonts you want to install into the ".fonts" directory. In most cases they will automatically show up in your applications. If they don't then you can try regenerating the font cache or rebooting your system.
