Right - picked up some true-type fonts and threw them into /usr/share/fonts where luxisans lives. Ran fc-cache. System picked right up on it and programs like xfce4-terminal, leafpad, etc see those new fonts.
However, no matter what I do, including tweaking my own .dillo/dillorc to include those fonts seems to fail. (Note: had to download dillorc manually).
I can get Dillo to use custom fonts on other distros, but for some reason, on PiCore 9, it is almost as if it is locked to the default console font.
I'm missing something, but can't put my finger on it since other programs immediately see the new fonts.
