I work on HP 19" monitors with 1280x1024 resolution. Last week I added a couple of LaTeX fonts to /usr/share/fonts/TTF and /usr/share/fonts/OTF and now the fonts in GUI applications such as LyX and gkrellm as well as all web sites in firefox are difficult to read because the letter stroke are not of the same width and the lines appear as adjacent dots rather than vector strokes.

I ran mkfontscale, mkfontdir, and fc-cache for both the TTF and OTF subdirectorys in /usr/share/fonts.

Not all installed fonts are available in firefox Edit -> Preferences -> Fonts. I keep trying to find one that provides the clarity I used to have but so far without success.

I've tried searching the web for fonts that display clearly at the monitor's default resolution but my search strings find only references to web browsers, text and GUI.

Why the display changed when new fonts were added is a puzzle to me, but regardless of reason I need to find a solution. All suggestions, recommendations, and other ideas are welcome.

Latex fonts are not OTF or TTF, are they? Somebody converted them.

I would step back. In runlevel 3, rename your /usr/share/fonts, & reinstall the font packages, which you will find with a grep in /var/lib/pkgtools/packages. Libreoffice has it's fonts in the main package, so do something similar there. |See if that sorts it.

Yes, I converted them for use with LaTeX. I could reinstall provided font packages; /var/lib/ has no pkgtools subdirectory and I've looked in /var/lib/packages/fonts/ several times. The main problem is with firefox: every web site has poor font quality.

This is the location used in -current (and future versions of Slackware). On 14.2 and earlier, the package database is in /var/log/packages/.

Sorry, my bad.

update: After more web research I learned about fc-list. The DejaVu fonts are installed and are present in /etc/fonts/conf.avail/ and ../conf.d/ but are not available to me as a user; fc-list does not list them.

Please suggest how to remedy this discrepancy.

TIA,

Rich
