NAME
SUNWkfb_config - fbconfig module for configuring the Sun XVR-2500
Graphics Device

/usr/lib/fbconfig/SUNWkfb_config [-propt] [-prconf]

/usr/lib/fbconfig/SUNWkfb_config [-help] [ -res ?]

DESCRIPTION
SUNWkfb_config configures the Sun XVR-2500 Graphics Accelerator and
some of the X11 window system defaults for the Sun XVR-2500.

The first form of SUNWkfb_config shown in the SYNOPSIS section stores
the specified options in the OWconfig file. These options initialize
the Sun XVR-2500 device the next time the window system is run on that
device. Updating options in the OWconfig file provides persistence of
these options across window system sessions and system reboots.

The second and third forms which invoke only the -prconf, -propt,
-help, and -res ? options, do not update the OWconfig file. For the
third form, all other options are ignored.

You can specify options for only one device at a time. If you want to
specify options for multiple devices, invoke the SUNWkfb_config utility
multiple times.

Only the Sun XVR-2500 options can be specified through the SUNWkfb_con‐
fig utility. 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 Xsun(1).

You can also specify which OWconfig file to update. By default, SUN‐
Wkfb_config updates the machine-specific file in the /etc/openwin
directory tree. Use the -file option to specify an alternate file. For
example, the system-global OWconfig file in the /usr/openwin directory
tree can be updated instead.

Both of these standard OWconfig files can only be written by root. Con‐
sequently, the SUNWkfb_config program, which is owned by the root user,
always runs with setuid root permission.

OPTIONS
The following options are supported:

-defaults

Resets all option values except -dev to their default values. This
option sets the resolution override to none which implies that the
last video mode setting is preserved. If no monitor is attached,
the video mode is set to 1152x900x66.

-deflinear true | false

This option selects the default X visual. The Sun XVR-2500 device
supports two types of visuals: linear and nonlinear. Linear visuals
are gamma corrected and 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 cor‐
rection enabled. If false, a non-linear visual that satisfies the
other default visual selection options, such as the default depth
and default class, is chosen as the default visual. See Xsun(1).

The -deflinear, -defoverlay, and -deftransparent options all select
the default X visual. Only one option may be enabled at the same
time. If more than one of these options is entered, the last selec‐
tion takes precedence and the other options are disabled.

-defoverlay true | false

This option selects the default X visual. The Sun XVR-2500 device
provides 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 will not damage windows created in other
visuals. The converse, however, is not true. Windows created in
other visuals will damage overlay windows.

If the value of this option is true, the overlay visual is the
default visual. The default depth is 8 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. See
Xsun(1).

-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 is 8 bit and the default class is PseudoColor. If
false, the nonoverlay visual that satisfies the other default vis‐
ual selection options, such as the default depth and the default
class, is chosen as the default visual. See Xsun(1).

-dev device-filename

Specifies the SunXVR-2500 special file. The default is
/dev/fbs/kfb0.

-doublehigh enable | disable

Configures the two outputs of the Sun XVR-2500 device into one ver‐
tical virtual display. The default is disable.

-doublewide enable | disable

Configures the two outputs of the Sun XVR-2500 device into one hor‐
izontal virtual display. The default is disable.

-file machine|system

Specifies which OWconfig file to update. If machine is specified,
the machine-specific OWconfig file in the /etc/openwin directory
tree is updated. If system is specified, the global OWconfig file
in the /usr/openwin directory tree is updated. If the specified
file does not exist, it is created. This option has no effect
unless other options are specified. The default is machine.

-g gamma-correction value

Changes the gamma correction value. All linear visuals provide
gamma correction. By default, the gamma correction value is 2.22.
Any value less than zero is illegal. 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 specified by gamma-
correction file. Format this file to provide the gamma correction
values for R, G, and B channels on each line. Specify each value in
hexadecimal format, separated from another value by at least one
space. The gamma-correction file file should provide 1024 such
triplets.

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 cor‐
rection is done using a user specified table, the gamma correction
value is undefined. By default, the window system assumes a gamma
correction value of 2.22 and loads the gamma table it creates cor‐
responding to this value.

The following is an example of a gamma-correction file file:

0x000 0x000 0x000
0x001 0x001 0x001
0x002 0x002 0x002
...
...
0x3ff 0x3ff 0x3ff

-help

Prints a list of the SUNWkfb_config command line options, along
with a brief explanation of each.

-multisample available | disable | forceon

If set to disable, no multisample is possible. If set to available,
multisample is possible but is selected on a per-window basis using
a library interface. If set to forceon, all Sun OpenGL windows are
rendered using multisampling. Query the number of samples used with
-propt or the xglinfo(1) utility. The xglinfo utility can return
the number of multisamples if -multisample is set to available. The
default is disable.

-offset xval yval

Adjusts the position of the specified stream by the value speci‐
fied. This option is only implemented in -doublewide and -double‐
high modes. For -doublewide, use the xval to position the rightmost
stream. Negative is left (overlaps with the left stream). For -dou‐
blehigh, use the yval to position the bottom stream. Negative is up
(overlaps with top stream). The default is [0, 0].

-prconf

Prints the Sun XVR-2500 hardware configuration. This is a typical
display:

-res video-mode

Specifies the video mode of the monitor connected to the specified
Sun XVR-2500 device.

You must specify the video mode with the -res option. You can spec‐
ify video-mode in the format of widthxheightxrate or as a symbolic
name. The format of these built-in video modes is:

widthxheightxrate

width is the screen width in pixels, height is the screen
height in pixels, and rate is the vertical frequency of the
screen refresh.

You can use the s suffix to specify stereo video modes. The s
suffix of 960x680x112s and 960x680x108s means that these are
stereo video modes.

As a convenience, the -res option also accepts formats with @
(at sign) in front of the refresh rate instead of x, as for
example, 1280x1024@76. Some video-modes supported by the Sun
XVR-2500 device may not be supported by the monitor.

You can obtain the list of video-modes supported by the Sun
XVR-2500 device and the monitor by running SUNWkfb_config with
the -res ? option. See SYNOPSIS.

Symbolic Names

Some video modes have symbolic names defined for them. Instead
of using the widthxheightxrate format, you can specify one of
the symbolic names as the argument to the -res option. The
meaning of the symbolic name none is that when the window sys‐
tem is run, the screen resolution is the video mode that is
currently programmed in the device.

The following symbolic names and their corresponding video
modes are supported:

Name Cprresponding Video Mode
svga 1024x768x60
1152 1152x900x76
1280 1280x1024x76
stereo 960x680x112s
none (see text above)

-samples 1 | 2 | 4 | 8 | 16

Requests the number of samples to compute per display pixel. The
requested number of samples per pixel is used if -multisample is
not disabled and resources exist for the request. Query the number
of samples used with -propt or the xglinfo(1) utility. The xglinfo
utility can return the number of multisamples after you specify the
option -multisample available. 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 ribbon
cable. Both devices should be running the same resolution and the
option should be issued when the window system is running. The
default is disable.

DEFAULTS
For a given invocation of the SUNWkfb_config command line, if an option
does not appear on the command line, the corresponding OWconfig option
is not updated and retains its previous value.

When the window system is run, if a Sun XVR-2500 option has never been
specified by way of SUNWkfb_config, a default value is used. The
options and their corresponding defaults are as follows:

Option Default
-dev /dev/fbs/kfb0
-file machine
-res none
-deflinear false
-defoverlay false
-deftransparent false
-slave disable
-g 2.22
-samples 4
-multisample disable
-doublewide disable
-doublehigh disable
-outputs direct
-offset [0,0]

The default for the -res option of none means that when the window sys‐
tem is run, the screen resolution is the video mode that is currently
programmed in the device.

EXAMPLES
Example 1: Switching the Resolution of the Monitor Type
