In X11, the default font path is:
/usr/openwin/lib/X11/fonts/F3, /usr/openwin/lib/X11/fonts/F3bitmaps, /usr/openwin/lib/X11/fonts/Type1, /usr/openwin/lib/X11/fonts/Speedo, /usr/openwin/lib/X11/fonts/misc, /usr/openwin/lib/X11/fonts/75dpi, /usr/openwin/lib/X11/fonts/100dpi
Note that the directory paths must be absolute.
To change the default font path, use the Font Administrator GUI or command-line tools included with Solaris. For information about Font Administrator, see the Font Administrator User's Guide.
