I installed teTeX-3.0 some time after building LyX-1.3.5 (Qt). I had been running teTeX-1.0.7. The Latin Modern fonts are installed as part of the teTeX-3.0 installation, and I can use them in the normal text of a LyX document via the FAQ instructions \usepackage{lmodern}.
However, the dropped capital package requires fonts specified with their nicknames "ptmr", "yfrak", "ecrm1000" etc. and when I try using "lmr" or "lmr10" I get LaTeX errors about missing TFM files. The TFM files seemed to get built automatically as needed for the ec fonts, so I'd think the same would happen for the lm family, but so far, they're not. Do I need to build TFM files manually, or is there something else I need to tell LyX? Do I need to add entries in the LyX configure script that makes symlinks in .../lyx/xfonts for various .pfb files? Something else? I thought I better ask here before charging off on a bunch of blind alleys. TIA, Jim
