LyX should not embed type 3 fonts in PDFs.

I don't perfectly understand:

"The line in the exported latex that seems to be causing the problem is:

\usepackage[T1]{fontenc}

This command typically causes latex to use type 1 fonts."

So, in exported latex files, you _have_ "\usepackage[T1]..."? Is the bug that such commands at the beginning of the file should make latex use type1 fonts and it uses type3 fonts instead?

Yes. It uses type 3 fonts if "\usepackage[T1]{fontenc}" is present in
the output file. Removing the line causes type 1 fonts to be used.

I'm not sure if the tetex and texlive people intentionally broke
compatibility (and lyx needs to change), if this is a bug on their end,
or if something funny has happened to my machine.

This copy of ubuntu is only a week or so old. I've tried removing and
reinstalling a few different sets of latex packages. All of them have
had the same behavior.

Thanks!

adding

    \usepackage{times}

to the latex file causes pdflatex it to use vector font.

To make LyX insert

    \usepackage{mathptmx}

(which has similar result) go to Document > Settings > Fonts and select in Roman: "Times Roman"

Which suggests that default font isn't available in vector format, or isn't selected for one reason or another. I think default font is computer modern - if i select that I get the ugly bitmap font again.

I confirm that on hardy. With \usepackage[T1]{fontenc} I get Type 3 fonts and Type 1 without.

Installing cm-super fonts fixes this issue.

I can confirm it (texlive 2007-13 on Ubuntu 8.04) and also that the installation of cm-super by synaptic or apt-get will solve it, without changes to the latex document. cm-super is not installed by default, perhaps because there are good alternative T1 fonts. I just want to mention Latin Modern, it's derived from the default Computer Modern fonts and provides very high quality. For information see the homepage: http://www.gust.org.pl/projects/e-foundry/latin-modern or look at the lmodern package on CTAN.

The LyX package should suggest cm-super, see Bug 261312.

This particular bug is being marked as a duplicate of bug 261312, because this bug will be fixed with that bug.
