Hello, I solved my problem with the screen fonts by choosing ttf fonts, as suggested to me by Stephen Carville. Thanks ! I now have problems with the math screen fonts : I do not have any symbol font apart from ttf-symbol. I know this is weird, but it's a fact. Now, if I write some equation with the symbol Pi for example (using \pi in math mode), I get the letter "p" instead of the symbol pi, and an error telling me that Symbol, blabla, is matched by fixed. So my question is : how can I tell Lyx to use ttf-symbol for the math mode ? Also, when I open the math panel, I get bizarre characters on the lower-left 6 buttons. I guess it's the same problem, not having symbol fonts apart from ttf. So again, I should set ttf-symbol for screen math font.
