  Orthogonally to your idea, I feel obliged to correct this statement.
Fontconfig configuration in Ubuntu got broken few months ago, and
last time I've checked it is still broken. Fonts rendered on Ubuntu
are colorbanded, which make them look blurry:

  Especially this comparison is worth looking:

When you zoom, you will see how Fedora 10 renders crisp fonts and
Ubuntu ones are surrounded by color stripes next to vertical lines.
