Can you tell me how?

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
 <match target="font">
  <edit mode="assign" name="autohint">
   <bool>true</bool>
  </edit>
 </match>
 <match target="font">
  <edit mode="assign" name="lcdfilter">
   <const>lcdlight</const>
  </edit>
 </match>
 <dir>~/.fonts</dir>
 <match target="font">
  <edit mode="assign" name="rgba">
   <const>vrgb</const>
  </edit>
 </match>
 <match target="font">
  <edit mode="assign" name="hinting">
   <bool>true</bool>
  </edit>
 </match>
 <match target="font">
  <edit mode="assign" name="hintstyle">
   <const>hintnone</const>
  </edit>
 </match>
 <match target="font">
  <edit mode="assign" name="antialias">
   <bool>true</bool>
  </edit>
 </match>
</fontconfig>

With this config I get no TT stem darkening at all.
If I change to hintstyle->hintslight stem darkening for TT gets switched
on, but then my OpenType fonts get distorted.
