I've installed all XFree86-ISO8859-2-1 fonts # ls /usr/share/fonts/X11/100dpi/lutRS18* /usr/share/fonts/X11/100dpi/lutRS18-ISO8859-10.pcf.gz /usr/share/fonts/X11/100dpi/lutRS18-ISO8859-13.pcf.gz /usr/share/fonts/X11/100dpi/lutRS18-ISO8859-14.pcf.gz /usr/share/fonts/X11/100dpi/lutRS18-ISO8859-15.pcf.gz /usr/share/fonts/X11/100dpi/lutRS18-ISO8859-2.pcf.gz /usr/share/fonts/X11/100dpi/lutRS18-ISO8859-3.pcf.gz /usr/share/fonts/X11/100dpi/lutRS18-ISO8859-4.pcf.gz /usr/share/fonts/X11/100dpi/lutRS18-ISO8859-9.pcf.gz But 0 fonts are found with fc-cache # fc-cache -f -v /usr/share/fonts/X11/100dpi /usr/share/fonts/X11/100dpi: caching, new cache contents: 0 fonts, 0 dirs To experiment, I copied a font over to the same directory: # cd /usr/share/fonts/X11/100dpi # wget https://github.com/ifax/HylaFAX/raw/master/etc/lutRS18.pcf # fc-cache -f -v /usr/share/fonts/X11/100dpi /usr/share/fonts/X11/100dpi: caching, new cache contents: 1 fonts, 0 dirs In order to be sure the single newly found font is the one I just downloaded: # fc-list | grep 100dpi /usr/share/fonts/X11/100dpi/lutRS18.pcf: LucidaTypewriter:style=Sans Yes, it is. The question is of course why the fonts I installed is not recongised but the one I downloaded is. I installed it on Ubuntu 18.04 through: # apt-get install xfonts-100dpi-transcoded whose content is here: https://packages.ubuntu.com/bionic/all/xfonts-100dpi-transcoded/filelist Thanks! _______________________________________________ Fontconfig mailing list Fontconfig@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/fontconfig
