Patched libraries are built against freetype 2.3.x (not currently in feisty) and include David Turner's subpixel rendering patches.

• To install the packages
  
  Code:

  sudo aptitude update
  sudo aptitude install libfreetype6 libcairo2 libxft2

• After the install, you may want reconfigure font settings. I'm currently using Feisty defaults (Native, Always, No bitmapped fonts) myself.
  
  Code:

  sudo dpkg-reconfigure fontconfig-config
  sudo dpkg-reconfigure fontconfig

• If you get errors about missing gpg key
  
  Code:

  wget http://www.telemail.fi/mlind/ubuntu/937215FF.gpg -O- | sudo apt-key add -

  (or alternatively)
  
  Code:

  gpg --keyserver subkeys.pgp.net --recv-keys 937215FF
  gpg --export --armor 937215FF | sudo apt-key add -

• GPG key to RAOF's repository (amd64 packages)
  
  Code:

  wget http://ubuntu.moshen.de/2F306651.gpg -O- | sudo apt-key add -

• If you later decide to go back to Ubuntu packages, you must downgrade all three installed packages
• You'll probably need to restart X-server after installing the packages to see the changes apply
