lyx math display problem

I have some problem with font display in math mode. Hopefully it's summed up in this screen capture (how do you resize the img using the BBCode?):

Symbols like $\partial, \star, \diamond$ are displayed incorrectly, replaced by @, ? etc when they are in {super,sub}scripts, compound fractions that make their size small.

This is lyx-1.6.7 running in Gentoo. I actually have a netbook running Ubuntu that does NOT have this problem, but I am not sure where the differences are.

Thanks.

NEW: TikZ book now 40% off at Amazon.com for a short time.

And: Currently, Packt sells ebooks for $4.99 each if you buy 5 of their over 1000 ebooks. If you choose only a single one, $9.99. How about combining 3 LaTeX books with Python, gnuplot, mathplotlib, Matlab, ChatGPT or other AI books? Epub and PDF. Bundle (3 books, add more for higher discount): https://packt.link/MDH5p

To be clear, the exported PDF looks fine, it's just the display on LyX? Does changing LyX's display fonts help (or at least make a difference)?

Yes, exported PDF is fine. Messing with fonts--three options Romans, Sans Serif, and Typewriter--changes fonts of the text, but do not help.

Your answer is a little unclear to me; under Tools > Preferences you can set the Screen fonts. (For the difference, see here.) For each of these categories, you should have as many options as there are fonts installed on your system. Is that what you changed? Out of curiousity, what fonts are you using? (The same on both setups?)

I had the same problem with Ubuntu 10.10 Lyx 1.6.7
Fist try to solve it with Qt configuration, as mention in
http://wiki.lyx.org/FAQ/Qt
does not work. Then I found ppa packages here
http://www.ubuntuupdates.org/packages/show/202612
in particular the one we need is ttf-lyx
Installing it with synaptic solve the problem.
