xfs, fs - X font server
xfs [-config configuration_file] [-port tcp_port]
Specifies the configuration file the font server will use.
Specifies a file descriptor which is already set up to be
used as the listen socket. This option is only intended to be used by the
font server itself when automatically spawning another copy of itself to handle
Specifies the TCP port number on which the server will listen
for connections. The default port number is 7100.
is the X Window System font server. It supplies
fonts to X Window System display servers.
The server is usually run by a system administrator, and started via boot files like /etc/rc.local. Users may also wish to start private font servers for specific sets of fonts.
On Tru64 UNIX systems, when the optional worldwide language-support subsets are installed, the /sbin/init.d/xfs script is available to create and delete configuration file information for xfs or to manually start and stop the server. The script command line has the following syntax:
The operation argument is one of the following keywords: Disables autostart of the font server by removing its configuration file. Enables autostart of the font server after each reboot by creating a configuration file. Starts the font server. Stops the font server.
script is provided mainly
for use with the
print filter, which uses the X
font server to access bitmap fonts that the filter converts to PostScript
for more information about this print filter.
This causes the font server to exit cleanly.
This signal is used to cause the server to re-read its configuration
This signal is used to cause the server to flush any cached
data it may have.
This signal is used to cause the server to reset, closing
all active connections and re-reading the configuration file.
The configuration language is a list of keyword and value pairs. Each keyword is followed by an '=' and then the desired value.
Recognized keywords include: The name of a configuration file that defines the code sets and character associations for glyph caching when the font server is reading fonts from another font server. The default cache-config file is /usr/var/X11/fs/fs_cache_config. If this configuration file is defined or if the default fs_cache_config file exists, glyph caching will be enabled when the font server is reading from a font server for those fonts whose code sets are specified in the file. Ordered list of font path element names. Use of the keyword "catalogue" is very misleading at present, the current implementation only supports a single catalogue ("all"), containing all of the specified fonts. List of alternate servers for this font server. Number of clients this font server will support before refusing service. This is useful for tuning the load on each individual font server. Whether this font server should attempt to clone itself when it reaches the client-limit. The default pointsize (in decipoints) for fonts that do not specify. The default is 120. Resolutions the server supports by default. This information may be used as a hint for pre-rendering, and substituted for scaled fonts which do not specify a resolution. A resolution is a comma-separated pair of x and y resolutions in pixels per inch. Multiple resolutions are separated by commas. Filename of the error file. All warnings and errors will be logged here. TCP port on which the server will listen for connections. The default port number is 7100. Whether syslog(3) on supported systems is to be used for errors. A list of font renderer libraries. Each entry is a library name that can optionally be followed by a semi-colon (;) and the name of the library's initialization routine. The following examples show three valid ways to format a renderers list entry:
# # sample font server configuration file #
# allow a max of 10 clients to connect to this font server client-limit = 10
# when a font server reaches its limit, start up a new one clone-self = on
# alternate font servers for clients to use alternate-servers = hansen:7101,hansen:7102
# where to look for fonts
# the first is a set of Speedo outlines, the second is a set of
# misc bitmaps and the last is a set of 100dpi bitmaps
catalogue = /usr/X11R6/lib/X11/fonts/speedo,
# in 12 points, decipoints default-point-size = 120
# 100 x 100 and 75 x 75 default-resolutions = 100,100,75,75 use-syslog = off
# dynamically loaded renderers
renderers = libfr_Type1.so;Type1RegisterFontFileFunctions,
One of the following forms can be used to name a font server that accepts TCP connections:
The hostname specifies the name (or decimal numeric address) of the machine on which the font server is running. The port is the decimal TCP port on which the font server is listening for connections. The cataloguelist specifies a list of catalogue names, with '+' as a separator.
Examples: tcp/fs.x.org:7100, tcp/18.104.22.168:7101/all.
One of the following forms can be used to name a font server that accepts DECnet connections:
The nodename specifies the name (or decimal numeric address) of the machine on which the font server is running. The objname is a normal, case-insensitive DECnet object name. The cataloguelist specifies a list of catalogue names, with '+' as a separator.
Multiple catalogues should be supported.
