NAME
fs - X font server
SYNOPSIS
fs [-config configurationfile] [-port tcpport]
DESCRIPTION
Fs is the X Window System font server. It supplies fonts
to X Window System display servers.
STARTING THE SERVER
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.
OPTIONS
-config configurationfile
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 tcpport
Specifies the TCP port number on which the server
will listen for connections.
SIGNALS
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
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:
X Version 11 Release 5 1
FS(1) FS(1)
catalogue (list of string)
Ordered list of font path element names. Use of
the keyword "catalogue" is very misleading at pre-
sent, the current 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.
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.
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 con-
nections.
use-syslog (boolean)
Whether syslog(3) (on supported systems) is to be
used for errors.
EXAMPLE
#
# 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:7001,hansen:7002
X Version 11 Release 5 2
FS(1) FS(1)
# 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/lib/fonts/speedo,
/usr/lib/X11/ncd/fonts/misc,
/usr/lib/X11/ncd/fonts/100dpi/
# in 12 points, decipoints
default-point-size = 120
# 100 x 100 and 75 x 75
default-resolutions = 100,100,75,75
FONT SERVER NAMES
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 run-
ning. 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 separa-
tor.
Examples: tcp/expo.lcs.mit.edu:7000,
tcp/18.30.0.212:7001/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 run-
ning. The objname is a normal, case-insensitive DECnet
object name. The cataloguelist specifies a list of cata-
logue names, with '+' as a separator.
Examples: DECnet/SRVNOD::FONT$DEFAULT, dec-
net/44.70::font$special/symbols.
