Dear Maintainer,

I wish to be able to use TTF fonts with ancient X programs that understand only
XLFD, so I installed the packages "xfstt" and "x11-xfs-utils".

Firstly I verified that the font server was running

    $ xfsinfo -server unix/:7101
    name of server: unix/:7101
    version number: 2
    vendor string:  HD
    vendor release number:  1
    maximum request size:   1024 longwords (8192 bytes)
    number of catalogues:   0
    Number of alternate servers: 0
    number of extensions:   0

next I verified that the font server knew about (at least some of) my
ttf fonts

    $ fslsfonts -server unix/:7101
    ...
    -ttf-bitstream-vera-bitstream vera sans mono-medium-r-normal-roman-0-0-0-0-m-0-iso8859-1
    ...

and eventually I tried to add the fonts served on "unix/:7101" using the
syntax that is documented in every place

    $ xset +fp unix/:7101
    xset:  bad font path element (#0), possible causes are:
        Directory does not exist or has wrong permissions
        Directory missing fonts.dir
        Incorrect font server address or syntax

so I have a running font server but no way of using it.

I know that I could use /etc/X11/Xconfig (?) but my system works w/o such a file
and I'd prefer to use the xset alternative because I fear to introduce new problems.

Thank you in advance for your attention,
                                                                         gb
