Release 6.1
NAME [Toc] [Back]
xfs - X font server
SYNOPSIS [Toc] [Back]
xfs [-config configuration_file] [-port tcp_port]
DESCRIPTION [Toc] [Back]
Xfs is the X Window System font server. It supplies fonts to X Window
System display servers.
STARTING THE SERVER [Toc] [Back]
The server is usually run by a system administrator, and started via
boot files like /sbin/init.d/xfs. Users may also wish to start
private font servers for specific sets of fonts.
OPTIONS [Toc] [Back]
-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 connections.
-port tcp_port
Specifies the TCP port number on which the server will listen
for connections.
SIGNALS [Toc] [Back]
SIGTERM This causes the font server to exit cleanly.
SIGUSR1 This signal is used to cause the server to re-read its
configuration file.
SIGUSR2 This signal is used to cause the server to flush any cached
data it may have.
SIGHUP This signal is used to cause the server to reset, closing all
active connections and re-reading the configuration file.
CONFIGURATION [Toc] [Back]
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:
catalogue (list of string)
Ordered list of font path element names. Use of the keyword
"catalogue" is very misleading at present, the current
Hewlett-Packard Company - 1 - HP-UX 11.23 May 2003
XFS(1) X Version 11 XFS(1)
Release 6.1
implementation only supports a single catalogue ("all"),
containing all of the specified fonts.
alternate-servers (list of string)
List of alternate servers for this font server.
client-limit (cardinal)
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.
default-resolutions (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 by commas.
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.
use-syslog (boolean)
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 fonts.

FONT SERVER NAMES [Toc] [Back]
One of the following forms can be used to name a font server that
accepts TCP connections:
tcp/hostname:port
tcp/hostname:port/cataloguelist
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/18.30.0.212:7101/all.
One of the following forms can be used to name a font server that
accepts DECnet connections:
decnet/nodename::font$objname
decnet/nodename::font$objname/cataloguelist
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.
