Jürgen, any idea on this one? lmodern must only be loaded if no other font has been loaded, i.e. if computer modern is the active font: \def\tempa{cmr} \ifx\f@family\tempa\usepackage{lmodern}\else\fi Jürgen
Is there any lyx file demonstrating the poor font quality? I have been unable to reproduce the font issue in master (after removing the line that forces latin modern in instant previews), even with the default setting of LyX that produces a PDF with bitmap fonts...
Anyway, here's a suggestion for getting those horrible bitmap fonts out of the way of new users, in a perfectly non-intrusive and backwards-compatible manner: just set Latin Modern to be the default choice for a new document. This would also solve the issue considered above. Note that I don't suggest to change the meaning of "Default" for roman fonts, but rather to force the user explicitly select "Default" over "Latin Modern" if he really wants to. I think it is always good when LyX shows the standard way. Then if the user wants poor bitmap fonts, that will be by choice.
(I know that I may suggest patches instead of ideas, but I do not have much time currently to become a new contributor to LyX, although I have been considering it.)
