How to disable font hinting in Arch linux Linux 08.08.2016

To disable font hinting in Arch linux create following file

# vim ~/.config/fontconfig/conf.d/10-hinting-slight.conf

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

That's it! Restart Chromium or Atom and you will see changes.

UPDATE 12.09.2016. Today freetype2 (2.6.5-2 -> 2.7-2) updated and font is ugly again. There is remark in pacman.log

The Arch-specific FT2_SUBPIXEL_HINTING has been removed. Subpixel hinting is now configured in /etc/profile.d/

So we should change something in /etc/profile.d/

# sudo vim /etc/profile.d/
export FREETYPE_PROPERTIES="truetype:interpreter-version=35"

But still fonts in Chromium and Atom are ugly, so I decided downgrade freetype2 (2.7-2 -> 2.6.5-2).

cd ~/temp
sudo pacman -U freetype2-2.6.5-2-x86_64.pkg.tar.xz

# add freetype2 to IgnorePkg in pacman.conf
# sudo vim /etc/pacman.conf
IgnorePkg   = freetype2
