Better Font Rendering

You might be able to get a smoother font rendering with one of the .fonts.conf below. Actually it depends on the kind of monitor used, so one of them might work better over the other, or none of them might work at all.

 <!DOCTYPE fontconfig SYSTEM "fonts.dtd">  true  none  false  hintnone  true

<!DOCTYPE fontconfig SYSTEM "fonts.dtd">  none  true  hintmedium  true

If fonts.conf doesn't work for GTK applications, try to add Xft sections to ~/.Xresources

! Render setting for cairo -> pango -> gtk Xft.dpi:       96 Xft.antialias: true Xft.hinting:   true Xft.rgba:      rgb Xft.hintstyle: hintslight

Finally don't forget to call xrdb -load ~/.Xresources to load new configurations.
