When I use math expressions with sub- or superscripts in a Latex Beamer document on Tumbleweed, dvips doesn’t find the correct fonts. Here is a minimal Latex document to reproduce the error:
\documentclass{beamer}
\begin{document}
$x_a$
\end{document}
Run latex and then dvips on the output. This produces errors of the form (pdflatex doesn’t work either):
kpathsea: Running mktexpk --mfmode ljfour --bdpi 600 --mag 1+57/600 --dpi 657 mathkerncmssi10
mktexpk: don't know how to create bitmap font for mathkerncmssi10.
mktexpk: perhaps mathkerncmssi10 is missing from the map file.
kpathsea: Appending font creation commands to missfont.log.
dvips: Font mathkerncmssi10 not found; using cmr10
</usr/share/texmf/fonts/pk/ljfour/public/cm/dpi600/cmr10.pk>
dvips: Checksum mismatch in font mathkerncmssi10
The package texlive-sansmathaccent which should contain the Metafont mathkerncmssi10 is installed, by it only contains the font metrics, not the bitmaps.
If I do the same on Leap 15.2, dvips takes the cmssi type1 fonts (e.g. /usr/share/texmf/fonts/type1/public/amsfonts/cm/cmssi10.pfb) from the package texlive-amsfonts. Of course I have the texlive-amsfonts package installed on Tumbleweed, too. As I understand, type1 fonts should be prefered over Metafont, anyway.
How can I configure texlive to use the type1 fonts (like Leap 15.2 does) and why isn’t this the default anymore?
