On my boxes (I've confirmed this now on two Linux machines, one 32-bit and one 64-bit), when I view a test document as PDF in Evince (using any of the three methods for generating PDFs), Evince's Help > About dialog says that it is "Using poppler/cairo (0.16.4)". It doesn't say that when I view DVI output.

I do most of my work in PDF and use DVI primarily for quick checks while writing (since it seems a bit faster than PDF ... although some of that may be Acrobat Reader being slow to load). As long as I remember not to freak out when I see an equal sign where it should be not equal, I'll be okay. I just thought that maybe this was a well-known symptom of a specific font file being missing. Thanks, Paul
