DESCRIPTION
The fbconf_xorg utility configures Frame Buffer devices and
some of the X11 window system defaults for Xorg by updating the xorg.conf configuration file.The first fbconf_xorg command form shown in the SYNOPSIS
section stores the specified option values in the xorg.conf configuration file. These settings are used to initialize the frame buffer device the next time the window system is run on that device. The persistence of these settings across window system sessions and system reboots is determined by the xorg.conf file. The second and third command forms display information, anddo not alter the xorg.conf file. The presence of the -help
and/or -res ? options will cause any other option (not shown
in the third form) to be ignored.SunOS 5.11 Last change: 26 Jan 2009 1
System Administration Commands fbconf_xorg(1M)
You can configure only one frame buffer device at a time. Toconfigure multiple devices, invoke the fbconf_xorg utility
separately for each device. Only frame buffer device options can be specified withfbconf_xorg. Use the normal window system options to specify
default depth (see svccfg(1M)), default visual class, and so forth. Specify these as device modifiers on the command line. See Xserver(1), part of the OpenWindows, not the SunOS, man page collection. You can specify which xorg.conf file to open. By default,fbconf_xorg opens the machine-specific file,
/etc/X11/xorg.conf. Use the -file option to specify an
alternate file. For example, the system-global file,
/usr/X11/xorg.conf, can be opened instead. These standard xorg.conf files can be written only by the superuser or someone with the Primary Administrator role.
Consequently, the fbconf_xorg program is run with setuid
root permission. OPTIONS The following options are supported for all frame buffer devices:-defaults
Sets configuration options for the specified device totheir default values. This does not affect the -res
video mode setting. See the device-specific portions of
the DEFAULTS section below.-dev device-file
Specifies the frame buffer device by either its full pathname or simple filename (for example, /dev/fbs/kfb0 or kfb0). Pathnames of installed devices can bedisplayed using the -list option to fbconfig(1M). If the
-dev option is omitted, the default device, /dev/fb, is
used.-file machine | system | config-path
Specifies which xorg.conf file to open. If machine isspecified, the machine-specific /etc/X11/xorg.conf file
is opened. If system is specified, the globalSunOS 5.11 Last change: 26 Jan 2009 2
System Administration Commands fbconf_xorg(1M)
/usr/X11/xorg.conf file is opened. The absolute pathname of a configuration file can be used instead. If the specified file does not exist and is to be updated, it will be created. The file system that will contain the xorg.conf file must be writeable by someone with
superuser-like privileges. This option has no effect
unless other options are specified. The default is machine.-help
Display the fbconf_xorg command line options that are
supported in conjunction with the frame buffer device, along with a brief explanation of each option. The framebuffer device can be specified using the -dev option.
-prconf
Display the current configuration for the frame buffer device and attached display device(s). The frame bufferdevice can be specified using the -dev option.

Set the video mode for the display device that is con-
nected to the frame buffer device.A list of video modes can be displayed using the -res ?
option.The basic format of a video-mode is widthxheightxrate,
SunOS 5.11 Last change: 26 Jan 2009 5
System Administration Commands fbconf_xorg(1M)
where: o width is the screen width in pixels. o height is the screen height in pixels. o rate is the vertical frequency of the screen refresh.A video-mode argument may have an @ (at sign) instead of
x preceding the refresh rate. For instance, 1280x1024x76 and 1280x1024@76 are equivalent.A video-mode name may carry additional information, as
with SUNW_STD_1280x1024x76.
The -res argument, auto, represents the video mode that
is currently programmed into the device. The argument, none, is a synonym for auto. Note that some video modes might be inappropriate for certain frame buffer devices and/or display devices.The -res option accepts suboption keywords following the
video-mode specification.
nocheckThe nocheck suboption causes the video-mode argument
to be accepted, regardless of whether it is sup-
ported by the currently attached monitor, whether it is known within the current configuration, and so forth. Note that using an unchecked, inappropriate video mode can leave the system without usable videooutput. This suboption is useful if a different mon-
itor is to be connected to the frame buffer device. This suboption also implies noconfirm. noconfirmIf the video-mode argument is unable to be vali-
dated, the default action is to display a warning message and ask the user whether to continue. The noconfirm suboption suppresses this confirmationrequest. This suboption is useful when fbconf_xorg
is being run from a shell script.The following device-specific options are supported for cer-
tain frame buffer devices. Unless specified otherwise, theseSunOS 5.11 Last change: 26 Jan 2009 6

options do not take effect until the user logs out and back in.-deflinear true | false
This option selects the default X visual. Two types of visuals are supported, linear and nonlinear. Linear visuals are gamma corrected. Nonlinear visuals are not. If the value of this option is true, the default visual is set to default depth 24 and the default class is TrueColor with gamma correction enabled. If false, a nonlinear visual that satisfies the other default visual selection options, such as the default depth and default class, is chosen as the default visual.The -deflinear, -defoverlay, and -deftransparent options
each select the default X visual. Only one of these may be enabled at a time. Enabling one causes the others to be disabled.-defoverlay true | false
This option selects the default X visual. The kfb deviceprovides an 8-bit PseudoColor visual whose pixels are
disjoint from the rest of the visuals. This is called the overlay visual. Windows created in this visual willnot damage windows created in other visuals. The con-
verse, however, is not true: Windows created in other visuals will damage overlay windows. If the value of this option is true, the overlay visualis the default visual. The default depth is 8-bit and
the default class is PseudoColor. If false, the non-
overlay visual that satisfies the other default visual selection options, such as the default depth and the default class, is chosen as the default visual.The -deflinear, -defoverlay, and -deftransparent options
each select the default X visual. Only one of these may be enabled at a time. Enabling one causes the others to be disabled.-deftransparent true | false

If the value of this option is true, the overlay visual used as the default is a transparent overlay visual. A visual with transparency supports a colormap with 255 colors and one transparent pixel. The default depth is8-bit and the default class is PseudoColor. If false,
the nonoverlay visual that satisfies the other default visual selection options, such as the default depth and the default class, is chosen as the default visual.The -deflinear, -defoverlay, and -deftransparent options
each select the default X visual. Only one of these may be enabled at a time. Enabling one causes the others to be disabled.-doublehigh enable | disable
Configures the two outputs of the frame buffer deviceinto one vertical virtual display. The default is dis-
able. The -doublewide and -doublehigh options are mutu-
ally exclusive. Enabling one causes the other to be dis-
abled.-doublewide enable | disable
Configures the two outputs of the frame buffer deviceinto one horizontal virtual display. The default is dis-
able. The -doublewide and -doublehigh options are mutu-
ally exclusive. Enabling one causes the other to be dis-
abled.-g gamma-correction-value
Sets the gamma correction value. All linear visuals pro-
vide gamma correction. The gamma correction value should be in the range, 0.1 to 10.0. The default is 2.22. This option can be used while the window system is running. Changing the gamma correction value affects all of the windows displayed by linear visuals.-gfile gamma-correction-file
Loads the gamma correction table from the file specifiedby gamma-correction-file. This text file specifies the
gamma correction values for the R, G, and B channels. Three consecutive values form an RGB triplet. For a kfb device, there must be exactly 256 RGB triplets. A value may be represented in hexadecimal, decimal, or octal format (for example, 0x3FF, 1023, or 01777,SunOS 5.11 Last change: 26 Jan 2009 8

respectively). Values are separated by one or more whi-
tespace or new line characters. Comments begin with ahash sign character (#) and end at the end of the line.
You can load the gamma correction table with this option while the window system is running. The new gamma correction affects all the windows being displayed using the linear visuals. When gamma correction is done usinga user-specified table, the gamma correction value (-g)
is undefined. By default, the window system assumes a gamma correction value of 2.22 and loads the gamma table it creates corresponding to this value.The following is an example of a gamma-correction-file
file:# Gamma Correction Table

If set to disable, no multisample is possible. If set to available, multisample is possible but is selected on aper-window basis using a library interface. If set to
forceon, all Sun OpenGL windows are rendered using mul-
tisampling. To query the number of samples used, specifythe -propt option or run the xglinfo utility. The
xglinfo utility can return the number of multisamples if-multisample is set to available. The default is dis-
able. xglinfo is described in the xglinfo(1) man page, in the Sun OpenGL man page collection.-offset x-val y-val
Adjusts the position of the specified stream by the value specified. This option is only implemented in-doublewide and -doublehigh modes. For -doublewide, use
the x-val to position the rightmost stream. Negative is
left (overlaps with the left stream). For -doublehigh,
use the y-val to position the bottom stream. Negative is
up (overlaps with top stream). The default is [0,0].SunOS 5.11 Last change: 26 Jan 2009 9
System Administration Commands fbconf_xorg(1M)
-samples 1 | 2 | 4 | 8 | 16
Requests the number of samples to compute per display pixel. The requested number of samples per pixel is usedif -multisample is not disabled and resources exist for
the request. To query the number of samples used,specify the -propt option or run the xglinfo utility.
The xglinfo utility can return the number of multisam-
ples after you specify the option -multisample avail-
able. The default is 4.-slave disable | multiview
If you set the multiview argument for the -slave option,
the device synchronizes video with a master through the multiview genlock ribbon cable. The system should be powered off whenever connecting or disconnecting thiscable. Both devices should be running the same resolu-
tion and the option should be issued when the window system is running. The default is disable. DEFAULTS Certain options have implied default arguments. The default argument is used when the option is not present on thefbconf_xorg command line. For instance, a default argument
for -dev is /dev/fb.
Options that set configuration state do not have implieddefaults. The -res option is one example. If a configuration
option is omitted from the fbconf_xorg command line, the
corresponding xorg.conf configuration setting will remain unchanged. The exception is that if configuration options are mutually exclusive, setting one will automatically unseteach of the others. An example is -deflinear, -defoverlay,
and -deftransparent.
If a configuration setting is not present in the configura tion file when the window system is run, a default value will be used. For instance, the default state associatedwith -res is auto. A setting might not be present in the
file, or the file itself might not exist, until fbconf_xorg
has been invoked with the corresponding command line option.The -defaults option sets the default values for most confi-
guration settings.SunOS 5.11 Last change: 26 Jan 2009 10
