Debian fonts
For my own reference: do “sudo apt-get install ttf-liberation” to get some sensible fonts on Debian :)
And if I end up on ubuntu 12.04 LTS, do this for firefox fix:
sudo rm /etc/fonts/conf.d/10-hinting-slight.conf
sudo ln -s /etc/fonts/conf.avail/10-hinting-full.conf /etc/fonts/conf.d/
