At initialization, most X servers and many X clients search a
list of directories, called a FontPath.
bash> grep '\(Load\)\|\(FontPath\)' /etc/X11/XF86Config
FontPath "/usr/X11R6/lib/X11/fonts/misc/"
FontPath "/usr/X11R6/lib/X11/fonts/Speedo/"
FontPath "/usr/X11R6/lib/X11/fonts/latin2/Type1/"
FontPath "/usr/X11R6/lib/X11/fonts/Type1/"
FontPath "/usr/X11R6/lib/X11/fonts/75dpi/"
FontPath "/usr/share/ghostscript/fonts/"
Load "speedo"
Load "type1"
Load "freetype"
Like most unix daemons, most X servers can also add font
directories dynamically.
bash> /etc/init.d/xdm restart
-or-
bash> xset fp+ /usr/X11R6/lib/X11/fonts/100dpi/
