0b. If I open ufonts.com_ti92pluspc.pfb with KFontFiew, then it calls the font "Ti92Pluspc, Regular". But if I execute "xlsfonts | grep [Pp]lus" I still get no hits.
1. There is no /var/log/Xorg.0.log file. (I saw that the wiki entry at https://wiki.archlinux.org/index.php/Font_Configuration says to check this, so I had already tried to do that and discovered that the file doesn't exist.)
notimportant but interesting?? Xorg.1.log maybe.
2. Executing "xset q" tells me (slightly reformatted so as to avoid wrapping issues): FontPath: /usr/share/fonts/X11/misc, /usr/share/fonts/X11/100dpi/:unscaled, /usr/share/fonts/X11/75dpi/:unscaled, /usr/share/fonts/X11/Type1, /usr/share/fonts/X11/100dpi, /usr/share/fonts/X11/75dpi, /var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType, built-ins
hmm, why is it /usr/share/fonts/X11/ it's just /usr/share/fonts/ here
3. The font I want to use is in one of those directories: $ ls -al /usr/share/fonts/X11/Type1 total 76 drwxr-xr-x 2 root root 4096 Oct 30 17:50 . drwxr-xr-x 3 root root 4096 Oct 30 17:50 .. -rw-r--r-- 1 root root 184 Oct 30 17:50 fonts.dir -rw-r--r-- 1 root root 184 Oct 30 17:50 fonts.scale -rw-r--r-- 1 root root 58184 Oct 30 17:50 ufonts.com_ti92pluspc.pfb $
