See Font configuration for the main article.

Configurations can vary to a degree. Please post Fontconfig configurations with an explanation for why they were done.

Hinted fonts

$XDG_CONFIG_HOME/fontconfig/fonts.conf
<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
	<match target="font">
		<edit mode="assign" name="antialias">
			<bool>true</bool>
		</edit>
		<edit mode="assign" name="embeddedbitmap">
			<bool>false</bool>
		</edit>
		<edit mode="assign" name="hinting">
			<bool>true</bool>
		</edit>
		<edit mode="assign" name="hintstyle">
			<const>hintslight</const>
		</edit>
		<edit mode="assign" name="lcdfilter">
			<const>lcddefault</const>
		</edit>
		<edit mode="assign" name="rgba">
			<const>rgb</const>
		</edit>
	</match>
</fontconfig>

No hinting for italic or bold

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
  <match target="font" >
    <edit mode="assign" name="autohint">  <bool>true</bool></edit>
    <edit mode="assign" name="hinting">	  <bool>false</bool></edit>
    <edit mode="assign" name="lcdfilter"> <const>lcddefault</const></edit>
    <edit mode="assign" name="hintstyle"> <const>hintslight</const></edit>
    <edit mode="assign" name="antialias"> <bool>true</bool></edit>
    <edit mode="assign" name="rgba">      <const>rgb</const></edit>
  </match>

  <match target="font">
    <test name="pixelsize" qual="any" compare="more"><double>15</double></test>
    <edit mode="assign" name="lcdfilter"><const>lcdlight</const></edit>
    <edit mode="assign" name="hintstyle"><const>hintnone</const></edit>
  </match>

  <match target="font">
    <test name="weight" compare="more"><const>medium</const></test>
    <edit mode="assign" name="hintstyle"><const>hintnone</const></edit>
    <edit mode="assign" name="lcdfilter"><const>lcdlight</const></edit>
  </match>

  <match target="font">
    <test name="slant"  compare="not_eq"><double>0</double></test>
    <edit mode="assign" name="hintstyle"><const>hintnone</const></edit>
    <edit mode="assign" name="lcdfilter"><const>lcdlight</const></edit>
  </match>

</fontconfig>

Sharp fonts

<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <match target="font">
    <edit name="antialias" mode="assign"><bool>true</bool></edit>
    <edit name="hinting" mode="assign"><bool>true</bool></edit>
    <edit name="hintstyle" mode="assign"><const>hintfull</const></edit>   <!-- try hintmedium if it looks bad -->
    <edit name="lcdfilter" mode="assign"><const>lcddefault</const></edit>
    <edit name="rgba" mode="assign"><const>rgb</const></edit>             <!-- set to match your display -->
  </match>
</fontconfig>

Enable anti-aliasing only for bigger fonts

Some users prefer the sharper rendering that anti-aliasing does not offer:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <match target="font">
    <edit name="antialias" mode="assign">
      <bool>false</bool>
    </edit>
  </match>

  <match target="font" >
    <test name="size" qual="any" compare="more">
      <double>12</double>
    </test>
    <edit name="antialias" mode="assign">
      <bool>true</bool>
    </edit>
  </match>

  <match target="font" >
    <test name="pixelsize" qual="any" compare="more">
      <double>16</double>
    </test>
    <edit name="antialias" mode="assign">
      <bool>true</bool>
    </edit>
  </match>
</fontconfig>

Default fonts

For font consistency, all applications should be set to use the serif, sans-serif, and monospace aliases, which are mapped to particular fonts by fontconfig. See Metric-compatible fonts for options and examples.

Japanese

Example fonts.conf which also specifies a default font for the Japanese locale (ja_JP) and keeps western style fonts for Latin letters.

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>

<!-- Default font (no fc-match pattern) -->
 <match>
  <edit mode="prepend" name="family">
   <string>Noto Sans</string>
  </edit>
 </match>

<!-- Default font for the ja_JP locale (no fc-match pattern) -->
 <match>
  <test compare="contains" name="lang">
   <string>ja</string>
  </test>
  <edit mode="prepend" name="family">
   <string>Noto Sans CJK JP</string>
  </edit>
 </match>

<!-- Default sans-serif font -->
 <match target="pattern">
   <test qual="any" name="family"><string>sans-serif</string></test>
   <!--<test qual="any" name="lang"><string>ja</string></test>-->
   <edit name="family" mode="prepend" binding="same"><string>Noto Sans</string>  </edit>
 </match>
 
<!-- Default serif fonts -->
 <match target="pattern">
   <test qual="any" name="family"><string>serif</string></test>
   <edit name="family" mode="prepend" binding="same"><string>Noto Serif</string>  </edit>
   <edit name="family" mode="append" binding="same"><string>IPAPMincho</string>  </edit>
   <edit name="family" mode="append" binding="same"><string>HanaMinA</string>  </edit>
 </match>

<!-- Default monospace fonts -->
 <match target="pattern">
   <test qual="any" name="family"><string>monospace</string></test>
   <edit name="family" mode="prepend" binding="same"><string>Inconsolatazi4</string></edit>
   <edit name="family" mode="append" binding="same"><string>IPAGothic</string></edit>
 </match>

Patched packages

Warning: AUR packages are maintained separately from applications in the official repositories. The whole graphical system can become inoperable, if the user-installed core graphical libraries become incompatible.
Note:
  • Configuration is usually necessary.
  • The new font rendering will not be available until applications restart.
  • Applications which statically link to a library will not be affected by the system library, or patches applied to it.
  • freetype2-ubuntu — Font configuration shipped with Ubuntu. [1] [2]
https://launchpad.net/ubuntu/+source/freetype || freetype2-ubuntuAUR fontconfig-ubuntuAUR
  • Infinality — Font configuration files, patches, and scripts.
https://github.com/bohoomil/fontconfig-ultimate || freetype2-infinalityAUR fontconfig-infinalityAUR

To restore the original packages, reinstall freetype2, cairo, and fontconfig as dependencies (use the --asdeps flag with pacman when reinstalling). Include lib32-cairo, lib32-fontconfig, and lib32-freetype2 if you also installed 32-bit versions.
