6 xfs - X font server
7
9 xfs [-config configuration_file] [-daemon] [-droppriv] [-ls lis‐
10 ten_socket] [-nodaemon] [-port tcp_port] [-user username]
11
13 Xfs is the X Window System font server. It supplies fonts to X Window
14 System display servers.
15
17 The server is usually run by a system administrator, and started via
18 boot files like /etc/rc.local. Users may also wish to start private
19 font servers for specific sets of fonts.
20
22 -config configuration_file
23 Specifies the configuration file the font server will use. If
24 this parameter is not specified, the default file,
25 /etc/X11/fs/config will be used.
26 -ls listen_socket
28 Specifies a file descriptor which is already set up to be used
29 as the listen socket. This option is only intended to be used
30 by the font server itself when automatically spawning another
31 copy of itself to handle additional connections.
32 -port tcp_port
34 Specifies the TCP port number on which the server will listen
35 for connections. The default port number is 7100.
36 -daemon Instructs xfs to fork and go into the background automatically
38 at startup If this option is not specified, xfs will run as a
39 regular process (unless xfs was built to daemonize by default).
40 -droppriv
42 If specified, xfs will attempt to run as user and group xfs
43 (unless the -user option is used). This has been implemented
44 for security reasons, as xfs may have undiscovered buffer over‐
45 flows or other paths for possible exploit, both local and
46 remote. With this option, you may also wish to specify "no-
47 listen = tcp" in the config file, which ensures that xfs will
48 not to use a TCP port at all.
49 -nodaemon
51 When xfs is built to daemonize (run in the background) by
52 default, this prevents that and starts xfs up as a regular
53 process.
54 -user username
56 This is equivalent to -droppriv except that xfs will run as
57 user username.
58
60 SIGTERM This causes the font server to exit cleanly.
61 SIGUSR1 This signal is used to cause the server to re-read its configu‐
63 ration file.
64 SIGUSR2 This signal is used to cause the server to flush any cached
66 data it may have.
67 SIGHUP This signal is used to cause the server to reset, closing all
69 active connections and re-reading the configuration file.
70
72 The configuration language is a list of keyword and value pairs. Each
73 keyword is followed by an '=' and then the desired value.
74 Recognized keywords include:
76 catalogue (list of string)
79 Ordered list of font path element names. The current implemen‐
80 tation only supports a single catalogue ("all") containing all
81 of the specified fonts. A special directory with symlinks to
82 font paths can be specified using a catalogue:<dir> entry. See
83 the CATALOGUE DIR section below for details.
84 alternate-servers (list of string)
86 List of alternate servers for this font server.
87 client-limit (cardinal)
89 Number of clients this font server will support before refusing
90 service. This is useful for tuning the load on each individual
91 font server.
92 clone-self (boolean)
94 Whether this font server should attempt to clone itself when it
95 reachs the client-limit.
96 default-point-size (cardinal)
98 The default pointsize (in decipoints) for fonts that don't spec‐
99 ify. The default is 120.
100 default-resolutions (list of resolutions)
102 Resolutions the server supports by default. This information
103 may be used as a hint for pre-rendering, and substituted for
104 scaled fonts which do not specify a resolution. A resolution is
105 a comma-separated pair of x and y resolutions in pixels per
106 inch. Multiple resolutions are separated by commas.
107 error-file (string)
109 Filename of the error file. All warnings and errors will be
110 logged here.
111 no-listen (trans-type)
113 Disable a transport type. For example, TCP/IP connections can
114 be disabled with no-listen tcp
115 port (cardinal)
117 TCP port on which the server will listen for connections.
118 use-syslog (boolean)
120 Whether syslog(3) (on supported systems) is to be used for
121 errors.
122 deferglyphs (string)
124 Set the mode for delayed fetching and caching of glyphs. Value
125 is "none", meaning deferred glyphs is disabled, "all", meaning
126 it is enabled for all fonts, and "16", meaning it is enabled
127 only for 16-bits fonts.
128
130 You can specify a special kind of font path in the form cata‐
131 logue:<dir>. The directory specified after the catalogue: prefix will
132 be scanned for symlinks and each symlink destination will be added as a
133 local fontfile FPE.
134 The symlink can be suffixed by attributes such as 'unscaled', which
136 will be passed through to the underlying fontfile FPE. The only excep‐
137 tion is the newly introduced 'pri' attribute, which will be used for
138 ordering the font paths specified by the symlinks.
139 An example configuration:
141 75dpi:unscaled:pri=20 -> /usr/share/X11/fonts/75dpi
143 ghostscript:pri=60 -> /usr/share/fonts/default/ghostscript
144 misc:unscaled:pri=10 -> /usr/share/X11/fonts/misc
145 type1:pri=40 -> /usr/share/X11/fonts/Type1
146 type1:pri=50 -> /usr/share/fonts/default/Type1
147 This will add /usr/share/X11/fonts/misc as the first FPE with the
149 attribute the attribute unscaled etc. This is functionally equivalent
150 to setting the following font path:
151 /usr/share/X11/fonts/misc:unscaled,
153 /usr/share/X11/fonts/75dpi:unscaled,
154 /usr/share/X11/fonts/Type1,
155 /usr/share/fonts/default/Type1,
156 /usr/share/fonts/default/ghostscript

185 use-syslog = off
186
189 One of the following forms can be used to name a font server that
190 accepts TCP connections:
191 tcp/hostname:port
193 tcp/hostname:port/cataloguelist
194 The hostname specifies the name (or decimal numeric address) of the
196 machine on which the font server is running. The port is the decimal
197 TCP port on which the font server is listening for connections. The
198 cataloguelist specifies a list of catalogue names, with '+' as a sepa‐
199 rator.
200 Examples: tcp/fs.x.org:7100, tcp/18.30.0.212:7101/all.
202 One of the following forms can be used to name a font server that
204 accepts DECnet connections:
205 decnet/nodename::font$objname
207 decnet/nodename::font$objname/cataloguelist
208 The nodename specifies the name (or decimal numeric address) of the
210 machine on which the font server is running. The objname is a normal,
211 case-insensitive DECnet object name. The cataloguelist specifies a
212 list of catalogue names, with '+' as a separator.
213 Examples: DECnet/SRVNOD::FONT$DEFAULT, decnet/44.70::font$special/sym‐
215 bols.
