I put in ~/.config/fontconfig/fonts.conf settings to turn on but it didn't appear to work. Then I used kde settings to fonts to turn on anti-aliasing, selecting RGB and hinting slight, and this appears to have changed to appearance.

So is kde ignoring the fonts.conf setting? kde settings does not include options such as lcdfilter either.
