7.4.2. Core X Font System
For compatibility, Red Hat Enterprise Linux provides the core X font subsystem, which uses the X Font Server (
xfs
) to provide fonts to X client applications.
The X server looks for a font server specified in the
FontPath
directive within the Files
section of the /etc/X11/xorg.conf
configuration file. Refer to Section 7.3.1.4, “Files
” for more information about the FontPath
entry.
The X server connects to the
xfs
server on a specified port to acquire font information. For this reason, the xfs
service must be running for X to start. For more about configuring services for a particular runlevel, refer to the chapter titled Controlling Access to Services in the System Administrators Guide.
7.4.2.1. xfs
Configuration
The
/etc/rc.d/init.d/xfs
script starts the xfs
server. Several options can be configured within its configuration file, /etc/X11/fs/config
.
The following lists common options:
alternate-servers
— Specifies a list of alternate font servers to be used if this font server is not available. A comma must seperate each font server in a list.catalogue
— Specifies an ordered list of font paths to use. A comma must seperate each font path in a list.Use the string:unscaled
immediately after the font path to make the unscaled fonts in that path load first. Then specify the entire path again, so that other scaled fonts are also loaded.client-limit
— Specifies the maximum number of clients the font server services. The default is10
.clone-self
— Allows the font server to clone a new version of itself when theclient-limit
is hit. By default, this option ison
.default-point-size
— Specifies the default point size for any font that does not specify this value. The value for this option is set in decipoints. The default of120
corresponds to a 12 point font.default-resolutions
— Specifies a list of resolutions supported by the X server. Each resolution in the list must be separated by a comma.deferglyphs
— Specifies whether to defer loading glyphs (the graphic used to visually represent a font). To disable this feature usenone
, to enable this feature for all fonts useall
, or to turn this this feature on only for 16-bit fonts use16
.error-file
— Specifies the path and file name of a location wherexfs
errors are logged.no-listen
— Preventsxfs
from listening to particular protocols. By default, this option is set totcp
to preventxfs
from listening on TCP ports for security reasons.Note
If usingxfs
to serve fonts over the network, remove this line.port
— Specifies the TCP port thatxfs
listens on ifno-listen
does not exist or is commented out.use-syslog
— Specifies whether to use the system error log.
