Am I the last person on the Earth to turn off font smoothing completely and use fonts perfectly hinted to the pixel grid? Can't get any sharper than that, and really helps with eye strain.
$ cat $HOME/.config/fontconfig/fonts.conf
<match target="font">
<edit name="rgba" mode="assign">
<const>none</const>
</edit>
<test qual="any" name="size" compare="more">
<double>1</double>
</test>
<test qual="any" name="size" compare="less">
<double>22</double>
</test>
<edit name="antialias" mode="assign">
<bool>false</bool>
</edit>
<edit name="hintstyle" mode="assign">
<const>hintfull</const>
</edit>
</match>
