This question already has an answer here:
I feel like this shouldn't be too hard to accomplish but I haven't been able to figure it out from some quick googling. On ubuntu, I have the font-stix package installed, and the fonts are actually on my computer (mathjax is rendering with it, for example), but I don't know/understand how to compile a regular LaTeX document (via, eg,
pdflatex) with the stix fonts.
edit: I came across that other link when I was googling but nothing there was able to help me get stix working.
