Re: non-antialiased font configuration

that's a perfect rendering, thank you!

additionally, my problem was that libreoffice installed 
"fonts-liberation2" which
is a disaster when you disable antialiasing.  removing 
"fonts-liberation2" and
sticking with "fonts-liberation" deb packages made all the difference.

I'm on KDE Neon now, so no gtk complications generally speaking.
