Comment 13 for bug 309792

I mistaken, you do not need to have that <dir> entry at all, unless it was added by Fontmatrix program like it was for on my system. Add remember that this will disable XFT system-wide. You need to add the following entries in ~/.fonts.conf in their respective sections:

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