--- Comment #10 from Bojan Smojver bojan@rexursive.com --- (In reply to Akira TAGOH from comment #9)
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>
This does not work for me in Gnome. I actually have to set hinting to full using Gnome Tweak Tool (or dconf) to get full hinting going.
That is the confusing bit for me. If I set full hinting in Gnome, but fontconfig has slight (i.e. the symlink in /etc/fonts/conf.d), the fonts are not rendered clearly. I tried symlinking the fontconfig's 10-hinting-full into /etc/fonts/conf.d, but that didn't work either. Neither did suggestion above.
PS. Note that I also use autohinting, by symlinking 10-autohint. Without that, all the fonts look way to thin for me.
