xfs - X font server
configuration_file] [-port tcp_port]
Xfs 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.
- -config configuration_file
- Specifies the configuration file the font server will use.
- -ls listen-socket
- 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 additional
- -port tcp_port
- Specifies the TCP port number on which the server
will listen for connections. The default port number is 7100.
The configuration language
is a list of keyword and value pairs. Each keyword is followed by an '=' and
then the desired value.
- This causes the font server to exit cleanly.
- This signal is used
to cause the server to re-read its configuration file.
- 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.
Recognized keywords include:
- catalogue (list of
- 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 string)
- 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.
- clone-self (boolean)
- Whether this font server should attempt to clone itself
when it reachs the client-limit.
- default-point-size (cardinal)
- The default pointsize
(in decipoints) for fonts that don't specify. The default is 120.
(list of resolutions)
- 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
- error-file (string)
- Filename of the error file. All warnings and
errors will be logged here.
- port (cardinal)
- TCP port on which the server
will listen for connections.
- no-listen (trans-type)
- Disable a transport type.
For example, TCP/IP connections can be disabled with no-listen tcp
- Whether syslog(3)
(on supported systems) is to be used for errors.
- deferglyphs (string)
- Set the mode for delayed fetching and caching of glyphs.
Value is "none", meaning deferred glyphs is disabled, "all", meaning it
is enabled for all fonts, and "16", meaning it is enabled only for 16-bits

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.
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.
Examples: DECnet/SRVNOD::FONT$DEFAULT, decnet/44.70::font$special/symbols.
