I don't recall how I came across the free Proggy font family but I wanted to try them out on my Ubuntu workstation for use in Eclipse. After some searching, I figured out how to install TrueType (.ttf) fonts and the process is pretty straightforward. I downloaded and unpacked the fonts into ~/.fonts, created a fonts.dir metadata file, added them to the font cache and when I restarted Eclipse, they were available.
~$ mkdir .fonts ~$ cd .fonts ~/.fonts$ wget http://www.proggyfonts.com/download/download_bridge.php?get=ProggyCl ean.ttf.zip ~/.fonts$ wget http://www.proggyfonts.com/download/download_bridge.php?get=ProggySq uare.ttf.zip ~/.fonts$ wget http://www.proggyfonts.com/download/download_bridge.php?get=ProggyS mall.ttf.zip ~/.fonts$ ttmkfdir -o fonts.dir ~/.fonts$ fc-cache -f -v
don't forget to unzip the three packages before running fc-cache
