 Posted: Thu Aug 05, 2010 7:06 am Post subject: lyx font problem in gentoo |
 |
|
I am having the following font problem in displaying certain math characters in lyx that occurs on both of my Gentoo machine, but not on my laptop running Ubuntu.
Math font works generally, but if I have something like the following:
| Code: | | \[ \frac{\partial}{} = \frac{\frac{\partial}{}}{} \] |
The first \partial displays correctly, but the second partial would be displayed as an "@" character.
Also characters like $\star$, $\prime$ works in regular font, but is displayed as something else when they are used in superscript or subscript.
There doesn't seems to be anything options to tweak the math fonts. Anyone?

FWIW, these all work as expected for me (lyx 1.6.7)

Maybe you can use lsof to see if the same fonts are being used, in Gentoo vs Ubuntu - something like:
lsof | grep -i lyx | egrep -i 'ttf|pfb' |

On Gentoo, I got:

On Ubuntu, I got the same list without the two Type1 fonts. Wondering if that's the issue. If so, I am not sure how to turn it off either. The pcb file belong to media-fonts/font-bitstream-type1. Here is a screen capture.

Compare the filesizes of the font files, between Gentoo and Ubuntu.
Fonts have "bugs" (e.g. incomplete character sets) and version numbers. |

The lyx fonts under /usr/share/fonts/lyx are identical, I even ran a diff on them.
The fonts under /usr/share/fonts/droid are different. There are a few more files in Gentoo than in Ubuntu, I think it's because Gentoo is using a newer version.
