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

~/.config/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>

Disable bold font

For when a font does not present itself well in bold and you can't disable bold fonts in the application (st for example).

...
<match target="pattern">
    <test qual="any" name="family">
        <string>Envy Code R</string>
    </test>
    <test name="weight" compare="more">
        <const>medium</const>
    </test>
    <edit name="weight" mode="assign" binding="same">
        <const>medium</const>
    </edit>
</match>
...

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>

 <match>
  <test compare="contains" name="lang">
   <string>ja</string>
  </test>
  <edit mode="prepend" name="family">
   <string>Noto Sans CJK JP</string>

 </match>

System-wide Noto Emoji fonts

Note: This example configuration enables Noto Emoji fonts to be used with GNOME and Chromium.
Firefox excluded due to multiple font configuration bugs.

Install the noto-fonts-emoji package. It provides both black-and-white and color font variant and sample configuration files for both.

Enable substitution for common color emoji fonts to Noto Color Emoji font:

# ln -s /etc/fonts/conf.avail/66-noto-color-emoji.conf /etc/fonts/conf.d/

Enable Noto Emoji black-and-white font as default text presentation of emoji:

# ln -s /etc/fonts/conf.avail/66-noto-emoji.conf /etc/fonts/conf.d/

Enable Noto Color Emoji as fallback for primary font families:

/etc/fonts/local.conf
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <match>
    <test name="family">
      <string>serif</string>
    </test>
    <edit name="family" mode="prepend" binding="weak">
      <string>Noto Color Emoji</string>
    </edit>
  </match>

  <match>
    <test name="family">
      <string>sans-serif</string>
    </test>
    <edit name="family" mode="prepend" binding="weak">
      <string>Noto Color Emoji</string>
    </edit>
  </match>

  <match>
    <test name="family">
      <string>monospace</string>
    </test>
    <edit name="family" mode="prepend" binding="weak">
      <string>Noto Color Emoji</string>
    </edit>
  </match>
</fontconfig>

Change Default, Serif and Sans-serif fonts in Chromium other than DejaVu to not contain emoji:

  • Open chrome://settings/fonts
  • To match GNOME select Cantarell 15px (11pt)

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[broken link: package not found] fontconfig-ubuntuAUR

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.
