--- Comment #9 from Akira TAGOH tagoh@redhat.com --- As long as the applications support reading something via dconf or using APIs doing that in a library, it does. otherwise not. that's why fontconfig followed it up that way. ideally the configuration tools in desktops should update $HOME/.config/fontconfig/conf.d for non-desktop-native apps as well. I'm tired to hear an complaint about the sort of this causing inconsistency configurations between fontconfig and desktops. please request desktops to improve.
For the permanent solution in user configuration, you can put this in $HOME/.config/fontconfig/conf.d
<fontconfig> <match> <edit name="hintstyle" mode="prepend"><const>choose from hintnone, hintslight, hintmedium, or hintfull what you prefer</const></edit> <!-- e.g. <edit name="hintstyle mode="prepend"><const>hintfull</const></edit> </match> </fontconfig>
or do the similar thing with fonts-tweak-tool for particular fonts
