Fix 1:

notice the dot in front of fonts

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

Fix 2:

sudo rm /etc/fonts/conf.d/10* sudo dpkg-reconfigure fontconfig

It doesn't seem to have any problems with the subpixel smoothing.
