Installing True Type Fonts in XFree4
(This was copied from: http://cloud13.com/ppc/pretty.html)
Installing true type fonts in XFree86 4 is easy because it has true type support built in.
So all you have to do is make a directory for your fonts, i used /usr/X11R6/lib/X11/fonts/local/.
Copy your fonts to that directory, and make sure that they are all lowercase. Then you need
to download ttmkfdir from
here, and run
these commands in your true type font directory:
ttmkfdir -o fonts.scale
mkfontdir
Now remove any lines in XF86Config which reference /usr/X11R6/lib/X11/fonts/local/
and add this line to your /var/X11R6/lib/XftConfig:
dir "/usr/X11R6/lib/X11/fonts/local/"
Now restart X, and you will have access to all your true type fonts.
