The PDF file is probably fine. The problem is that acrobat reader <4.05 had bugs with fonts. It is still desirable to create a PDF with no type 3 fonts. Read Extended.lyx to learn how to do that. Note that while using pslatex will give you type 1 fonts for text, latex will still use some Computer Modern fonts for some symbols, for example the minus sign. So you should always set up your ~/.dvips so dvips will use type1 fonts.
