Si las fuentes se ven mal, sin resolucion entonces estas indicaciones puede ayudar
1. Instalar ttf-mscorefonts-installer
2. Seguir los siguientes pasos tomados de http://fak3r.com/geek/howto-fix-fonts-in-debian-lennysid/
dpkg-reconfigure fontconfig-config
In the dialog choose these options; Autohinter, Automatic and No. Now issue this command:
dpkg-reconfigure fontconfig
Logout and log back into your desktop and your fonts should be *noticeably* nicer looking. Of course after that you have to drive yourself crazy tweaking the settings for autohinting and RGB lines, installing any and all ttf-* fonts apt-get sees, but hey, that’s what choice is all about!
