DESCRIPTIONSUNWpfb_config is the XVR-50 and the Sun XVR-100 device dependent layer
for fbconfig(1M). It configures the XVR-50 and the Sun XVR-100 Graphics
Accelerator and some of the X11 window system defaults for the XVR-50
and Sun XVR-100. The Sun XVR-100 provides the capability to drive two
monitors, each with a unique video stream (Stream #1 and Stream #2).
The XVR-50 drives one video stream.
The first two forms of SUNWpfb_config shown in the SYNOPSIS section
sets options for the XVR-50 and the Sun XVR-100 devices. It stores the
specified options in the OWconfig file. These options initialize the
XVR-50 and the Sun XVR-100 devices the next time the window system is
run on that device. Updating options in the OWconfig file provides per‐
sistence of these options across window system sessions and system
reboots. The XVR-50 and the Sun XVR-100 devices are immediately pro‐
grammed if you specify the -res now.
The third form, which invokes the -prconf and -propt options, queries
the XVR-50 and the Sun XVR-100 device for status.
The fourth form, which invokes the -help, and -res \? options, provides
instruction on using SUNWpfb_config. Additionally, for the fourth form
all other options are ignored.
You can only specify options for only one XVR-50 or Sun XVR-100 device
at a time. If you want to specify options for multiple XVR-50 or Sun
XVR-100 devices, you must use multiple invocations of the SUNWpfb_con‐
fig command.
You can only use SUNWpfb_config to specify XVR-50 or Sun XVR-100 spe‐
cific options. You can use the normal window system options to specify
the default depth, default visual class and so forth as device modi‐
fiers on the command line when the X Server is started. See dtlogin(1)
for information regarding the Xservers File.
You can also specify the OWconfig file to update. The machine-specific
file in the /etc/openwin directory tree is updated by default. You can
used the -file option to specify an alternate file. For example, you
can update the system-global OWconfig file in the /usr/openwin direc‐
tory tree instead.
OPTIONS
The following options are supported:
-defaults
Reset all option values to their default values.
-depth 8 | 24
Set the depth (bits per pixel) for the window system. Possible val‐
ues for the -depth option are 8 or 24. You must log out of the cur‐
rent window system session and log back in again for the change to
take effect. Any depth setting in the Xserver command line takes
precedence over what is set using fbconfig. The default is 8. This
option is only available with Solaris 8 or Solaris 9.
-dev device-filename
Specify the XVR-50 or the Sun XVR-100 special file. The default is
/dev/fb.
-doublehigh enable | disable
Configure the two outputs of the Sun XVR-100 into one vertical vir‐
tual display. You must log out of the current window system session
and log back in again for the change to take effect. The default is
disable.
-doublewide enable | disable
Configure the two outputs of the Sun XVR-100 into one horizontal
virtual display. You must log out of the current window system ses‐
sion and log back in again for the change to take effect. The
default is disable.
-fake8 enable | disable
Enable or disable simple 8 bit X windows to be rendered without a
hardware colormap to reduce colormap flashing. You might notice
performance reductions. You must log out of the current window sys‐
tem session and log back in again for the change to take effect.
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 enable | disable | gamma-value
This option allows you to change 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. Chang‐
ing the gamma correction value will affect all the windows being
displayed using the linear visuals. You must log out of the current
window system session and log back in again for the change to take
effect. The default is disable.
-help
Print a list of the SUNWpfb_config command line options, along with
a brief explanation of each option.
-offset xval yval
Adjust the position of the secondary stream on the Sun XVR-100.
This option is currently implemented only for the -doublewide and
-doublehigh modes. For -doublewide, use the xval to position the
DVI stream, if -outputs are direct (VGA stream if -outputs are
swapped). A negative value specifies the overlapped region with the
primary stream. This is similar for -doublehigh, except the yval is
used. Positive values are treated as 0. You must log out of the
current window system session and log back in again for the change
to take effect. The default is [0, 0].
-outputs swapped | direct
Reverse the positions of the -doublewide or -doublehigh outputs
relative to each other on the Sun XVR-100. You must log out of the
current window system session and log back in again for the change
to take effect. The default is direct.
-propt
Print the current values of all XVR-50 and Sun XVR-100 options in
the OWconfig file specified by the -file option for the device
specified by the -dev option. Print the values of options as they
will be in the OWconfig file after the call to SUNWpfb_config com‐
pletes.
This is a typical display for the Sun XVR-100:
--- Graphics Configuration for /dev/fbs/pfb0 ---
OWconfig: machine
Video Mode: not set
Depth: not set
Screen Information:
Doublewide: Disable
Doublehigh: Disable
Offset/Overlap: [0.0]
Output Configuration: Direct
Fake8 Rendering: Disable
Gamma Configuration: Disable
-prconf
Print the XVR-50 and Sun XVR-100 hardware configuration.
This is a typical display:
--- Hardware Configuration for /dev/fbs/pfb0 ---
Type: XVR-100
ASIC: version 0x5159 REV : version 0x3000000
PROM: version 4.2
Monitor/Resolution Information:

Current resolution setting: 1152x900x66
Depth Information:
Possible depths: 8, 24
Current depth: 8
-res video-mode [ now | try [ noconfirm | nocheck ]]
Specify the video mode that drives the monitor connected to the
specified XVR-50 or Sun XVR-100 device.
Video modes are built-in. The -res option requires you to specify
the video-mode. You can specify video-mode in the format of widthx‐
heightxrate or as a symbolic name.
video-mode Specify video-mode in the format of widthx‐
heightxrate, where width is the screen width in
pixels, height is the screen height in pixels,
and rate is the vertical frequency of the screen
refresh. An example video mode specified in this
format is 1280x1024x60.
The -res option also accepts formats with @ pre‐
ceding the refresh rate instead of x
(1280x1024@60).
Symbolic Names Some video modes have symbolic names defined for
them. Instead of the form widthxheightxrate for‐
mat, 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
system is run the screen resolution is the video
mode that is currently programmed in the device.
The following symbolic names and their corre‐
sponding video modes are supported:
Name Corresponding Video Mode
svga 1024x768x60
1152 1152x900x76
1280 1280x1024x75
none Programmed video mode
Some video-modes, supported by XVR-50 and Sun XVR-100, might not be
supported by the monitor. Use the -res \? option to obtain the list
of video-modes supported by the XVR-50 and Sun XVR-100 device and
the monitor.
The -res option also accepts additional, optional arguments immedi‐
ately following the video mode specification. The following addi‐
tional, optional arguments are supported:
nocheck If present, the normal error checking based on the
monitor sense code is suspended. The video mode speci‐
fied by the user is accepted regardless of whether it
is appropriate for the currently attached monitor.
This option is useful if a different monitor is to be
connected to the XVR-50 or the Sun XVR-100 device. Use
of this option implies noconfirm as well.
noconfirm You could put the system into an unusable state using
the -res option, which has no video output. To reduce
the chance of this, the default behavior of SUNW‐
pfb_config is to print a warning message and to ask
the user whether to continue. The noconfirm option
bypasses this confirmation. This option is useful when
you are running SUNWpfb_config from a shell script.
now If present, updates the video mode in the OWconfig
file and immediately programs the XVR-50 or Sun
XVR-100 device to display this video mode. This is
useful for changing the video mode before starting the
window system.
Do not use this suboption with SUNWpfb_config while
the configured device is being used (for example,
while running the window system) as unpredictable
results can occur.
If you want to run SUNWpfb_config with the now subop‐
tion, first bring the window system down, and executed
from the console command line. If you use the now
option within a window system session, the video mode
is changed immediately. The width and height of the
affected screen will not change until the window sys‐
tem is exited and re-entered again. Additionally, the
system might not recognize changes in stereo mode.
This usage is discouraged.
try If present, programs the specified video mode on a
trial basis. You are asked to confirm the video mode
by entering a y within 10 seconds. You can terminate
the trial before 10 seconds by entering any character
but y or <RETURN>.
This sub-option should not be used with SUNWpfbconfig
while the configured device is being used (for exam‐
ple, while running the window system) as unpredictable
results may occur. To run SUNWpfbconfig with the try
sub-option, the window system should be brought down
first, and executed from the console command line.
-res \?
Print a list of defined video-mode names.
DEFAULTS
For a given invocation of SUNWpfb_config command line if an option does
not appear on the command line, the corresponding OWconfig option is
not updated; it retains its previous value.
When the window system is run, if a XVR-50 or Sun XVR-100 option has
never been specified by SUNWpfb_config, a default value is used. The
options and their corresponding defaults for a XVR-50 are as follows:
Option Default
-dev /dev/fb
-file machine
-res none
-fake8 disable
-g disable
The options and their corresponding defaults for a Sun XVR-100 are as
follows:
Option Default
-dev /dev/fb
-file machine
-res none
-fake8 disable
-g disable
-depth 8 (Solaris 8 and Solaris 9)
-doublewide disable
-doublehigh disable
-outputs direct
-offset [0,0]
The default for the -res option none means that when the window system
is run, the screen resolution will be the video mode that is currently
programmed in the XVR-50 or Sun XVR-100 PROM.
This provides compatibility for users who are used to specifying the
device resolution through the XVR-50 or the Sun XVR-100 PROM. On some
devices (e.g. GX) this is the only way of specifying the video mode.
This means that the PROM ultimately determines the default XVR-50 or
Sun XVR-100 video mode.
EXAMPLES
