On May 9th RedHat made freely available a pack of fonts called Liberation Fonts.

There are three sets of fonts in the pack :-

• Sans - which is a substitute for Arial, Albany, Helvetica, Nimbus Sans L, and Bitstream Vera Sans.
• Serif - which is a substitute for Times New Roman, Thorndale, Nimbus Roman, and Bitstream Vera Serif.
• Mono - substitute for Courier New, Cumberland, Courier, Nimbus Mono L, and Bitstream Vera Sans Mono.

I am using Ubuntu with the Fluxbox desktop at the moment , so I installed them like this :-

1. Download the liberation-fonts-ttf.tar.gz tarball from the RedHat Liberation Fonts page.
2. Unpack the fonts into a new directory at /usr/share/fonts/truetype/ttf-liberation/
3. Refresh the font cache by running sudo fc-cache -f -v
4. Might as well remove the dodgy Microsoft fonts while sudo is hot with sudo dpkg --remove msttcorefonts
5. ...and refresh the font cache again , sudo fc-cache -f -v
6. Now just restart Firefox or any application you were using to see the difference.

Here is a nice recursive screenshot of what they look like for me.

Thanks RedHat , good work.
