Graphics Administration Guide (April 2009)
The VendorName is an optional entry and is used to specify the monitor's manufacturer.
The ModelName is an optional entry that is used to specify the monitor model.
HorizSync gives the range(s) of horizontal sync frequencies supported by the monitor.
horizsync-range may be a comma separated list of either discrete values or ranges of values. A
range of values is two values separated by a dash. By default the values are in units of kHz. They
may be specified in MHz or Hz if MHz or Hz is added to the end of the line. The data given here
is used by the X Server to determine if video modes are within the specifications of the monitor.
This information should be available in the monitor's handbook. If this entry is omitted, a default
range of 28-33 kHz is used. Source: XF86Config man page.
VertRefresh gives the range(s) of vertical refresh frequencies supported by the monitor.
vertrefresh-range may be a comma separated list of either discrete values or ranges of values. A
range of values is two values separated by a dash. By default the values are in units of Hz. They
may be specified in MHz or kHz if MHz or kHz is added to the end of the line. The data given
here is used by the X Server to determine if video modes are within the specifications of the
monitor. This information should be available in the monitor's handbook. If this entry is omitted,
a default range of 43-72Hz is used. Source: XF86Config man page.
DisplaySize is an optional entry which gives the width and height, in millimeters, of the picture
area of the monitor. If given these values are used to calculate the horizontal and vertical pitch
(DPI) of the screen. Source: XF86Config man page.
Device section
The configuration file may have multiple Device sections. There must be at least one, for the
video card being used. Device sections have the following format:
Section “Device”
Identifier “DeviceID”
Devicefile “/dev/gvid”
Option …
. . .
EndSection
The Identifier entry specifies the unique name for this graphics device. It must match a DriverID
in the active Screen section.
sample XF86Config file
# This is a sample XF86Config file. It can be cut from this document
# and placed in the /etc/X11/XF86Config file.
#
# The config file has a hierarchical “Section” structure along
# with some standalone “Sections.”
#
# The standalone sections are the Files, Module, and DRI Sections.
# There may only be one of each of these sections in the config file.
#
# The hierarchical section consists of the ServerLayout, InputDevice,
# Screen, Monitor, and Device sections. There may be multiple sections
# of each.
#
# Each screen section in turn specifies a Monitor and a Device
# section.
#
# Check the document “Graphics Administration Guide” for complete
# documentation of the config file organization and description of all
# options. An online version of the Graphics Administration Guide is

# The ServerLayout section specifies the input and output devices that are
