Muses posted a guide about improving the font rendering in Gentoo Linux
Before I begin, full credits must go to PaulBredbury, Infinality and bi3l (gentoo-forums nick) who have done all the hard work on this.Improved Font Rendering in Gentoo
Here’s my guide to get (what I believe) the best font rendering in Gentoo. Note that this uses ebuilds from an overlay, and thus is not officially supported by Gentoo. If you don’t know what an overlay is, look it up (and look up layman as well) on the internet. When you have your box configured to work with overlays, continue with this guide.
