Funtoo Linux is planning to integrate the LCD-filtering overlay into the main tree in order to have a very good font experience. Until then, the overlay is available via layman and some manual steps. (as described below). The overlay consists of patched versions of {{Package|x11-libs/cairo}}, {{Package|x11-libs/libXft}}, {{Package|app-admin/eselect-fontconfig}}, {{Package|media-libs/freetype}} with the aim of getting nice hinting and rendering, and emulating the appearance of Ubuntu/MS Windows/Mac OS X fonts.

LCD-Filtering overlay

Funtoo Linux is planning to integrate the LCD-filtering overlay into the main tree in order to have a very good font experience. Until then, the overlay is available via layman and some manual steps. (as described below). The overlay consists of patched versions of x11-libs/cairo, x11-libs/libXft, app-admin/eselect-fontconfig, media-libs/freetype with the aim of getting nice hinting and rendering, and emulating the appearance of Ubuntu/MS Windows/Mac OS X fonts.

Install the packages

# emerge -uN fontconfig freetype cairo libXft

Advanced configuration

Fontconfig

Default configuration

# eselect fontconfig enable 10-antialias.conf
# eselect fontconfig enable 10-autohint.conf  
# eselect fontconfig enable 10-hinting.conf  
# eselect fontconfig enable 10-hinting-slight.conf  
# eselect fontconfig enable 10-sub-pixel-rgb.conf  
# eselect fontconfig enable 11-lcdfilter-default.conf  
# eselect fontconfig enable 70-no-bitmaps.conf  
# eselect fontconfig disable 10-hinting-full.conf  
# eselect fontconfig disable 10-hinting-medium.conf  
# eselect fontconfig disable 10-no-sub-pixel.conf  
# eselect fontconfig disable 10-sub-pixel-bgr.conf  
# eselect fontconfig disable 10-sub-pixel-vbgr.conf  
# eselect fontconfig disable 10-sub-pixel-vrgb.conf  
# eselect fontconfig disable 10-unhinted.conf

Linux configuration

Same as default configuration except:

# eselect fontconfig enable 21-hinting-small-aquabase-slight.conf
# eselect fontconfig enable 21-hinting-small-browallia-slight.conf  
# eselect fontconfig enable 22-hinting-courier-italic-slight.conf

Infinality’s configuration

Same as default configuration except:

# eselect fontconfig enable 15-hinting-tt-instructed-full.conf
# eselect fontconfig enable 20-hinting-small-fonts-slight.conf  
# eselect fontconfig enable 21-hinting-small-aquabase-slight.conf  
# eselect fontconfig enable 21-hinting-small-browallia-slight.conf  
# eselect fontconfig enable 22-hinting-courier-italic-slight.conf  
# eselect fontconfig enable 25-hinting-small-arial-black-slight.conf

Windows configuration

Same as default except:

# eselect fontconfig disable 10-autohint.conf
# eselect fontconfig disable 10-hinting-slight.conf  
# eselect fontconfig enable 10-hinting-full.conf  
# eselect fontconfig enable 15-hinting-non-tt-instructed-slight.conf  
# eselect fontconfig enable 20-hinting-small-fonts-slight.conf  
# eselect fontconfig enable 21-hinting-small-aquabase-slight.conf  
# eselect fontconfig enable 21-hinting-small-browallia-slight.conf  
# eselect fontconfig enable 22-hinting-courier-italic-slight.conf  
# eselect fontconfig enable 25-hinting-small-arial-black-slight.conf

OSX configuration

Same as default configuration except:

# eselect fontconfig disable 10-autohint.conf
# eselect fontconfig disable 10-hinting.conf  
# eselect fontconfig disable 10-hinting-slight.conf  
# eselect fontconfig enable 10-unhinted.conf  
# eselect fontconfig enable 15-hinting-tt-instructed-none.conf

Freetype

Freetype can be configured through environment variables (see /etc/env.d/99lcdfilter for a list of the variables and their description). Those variables can be overridden on a per-user basis by either redefining them in a startup file (such as ~/.bash_profile) or by sourcing the /usr/lib/ft-settings.sh script with the desired style in parameter (you can, of course, source the script from a startup file).

usage: source ft-settings.sh <style>

Possible styles:   
  default      - Use default settings.  A compromise that should please most people  
  osx          - Simulate OSX rendering  
  ubuntu       - Simulate UBUNTU rendering  
  linux        - Generic Linux style - no snapping or certain other tweaks  
  windows      - Simulate Windows rendering  
  vanilla      - Just subpixel hinting

Infinality styles:  
  classic      - Infinality rendering circa 2010. No snapping  
  nudge        - CLASSIC with lightly stem snapping and tweaks  
  push         - CLASSIC with medium stem snapping and tweaks  
  shove        - Full stem snapping and tweaks without sharpening  
  sharpened    - Full stem snapping, tweaks, and Windows-style sharpening  
  infinality   - Settings used by Infinality

LibXft

Only legacy programs still use libXft. The default configuration is defined in /usr/share/X11/app-defaults/Xft. It can be overriden on a per-user basis in the ~/.Xresources or ~/.Xdefaults files :

Xft.antialias:  1
Xft.autohint:   0  
Xft.dpi:        96  
Xft.hinting:    1  
Xft.hintstyle:  hintfull  
Xft.lcdfilter:  lcddefault  
Xft.rgba:       rgb
