GFXconfig(1M)
NAME
pgxconfig, GFXconfig, TSIgfxp_config - configure the PGX32
(Raptor GFX) Graphics Accelerator
SYNOPSIS
/usr/sbin/pgxconfig [-dev device-filename] [-res video-mode
[try | noconfirm | nocheck] ] [-file machine | system] [-
depth 8 | 24] [-24only true | false] [-cachedpixmap true |
false] [-defaults]
/usr/sbin/pgxconfig [-propt] [-prconf]
/usr/sbin/pgxconfig [-help] [-res ?]
/usr/sbin/pgxconfig [-i]
DESCRIPTION
The pgxconfig utility configures the PGX32 (Raptor GFX)
Graphics Accelerator and some of the X11 window system
defaults for PGX32 (Raptor GFX). A previous version of this
utility was named GFXconfig.
The first form of pgxconfig shown in the synopsis above
stores the specified options in the OWconfig file. These
options are used to initialize the PGX32 (Raptor GFX) 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, third, and fourth 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.
The -i option starts pgxconfig in interactive mode.
Options may be specified for only one PGX32 (Raptor GFX)
device at a time.
Only PGX32 (Raptor GFX)-specific options can be specified
through pgxconfig. The normal window system options for
specifying default depth, default visual class and so forth
are still specified as device modifiers on the openwin com-
mand line. See the Xsun(1) manual page available with the
SUNWxwman package.
The user can also specify the OWconfig file that is to be
updated. By default, the machine-specific file in the
/usr/openwin directory tree is updated. The -file option can
be used to specify an alternate file to use. For example,
the system-global OWconfig file in the /etc/openwin
directory tree can be updated instead.
Both of these standard OWconfig files can only be written by
root.
OPTIONS
The following options are supported:
-cachedpixmap true | false
When set to false, it forces the PGX32 (Raptor GFX)
device to use 24-bit only when running OpenWindows.
The default value is true.
Certain applications make use of a cached pixmap when
writing to the display device. Such a technique can
cause garbled output and can cause the X server to
crash. If you experience such behavior, try setting
the -cachedpixmap option to false.
-defaults
Reset all option values to their default values.
-depth 8 | 24
Sets the screen depth to 8 or 24 bits per pixel. 24
bits per pixel enables TrueColor graphics in the win-
dow system.
-dev device-filename
Specify the PGX32 (Raptor GFX) special file. The
default is /dev/fbs/gfxp0, or /dev/fbs/raptor0 if
applicable.
-file machine | system
Specify which OWconfig file to update. If machine, the
machine-specific OWconfig file in the /etc/openwin
directory tree is used. If system, the global OWconfig
file in the /usr/openwin directory tree is used. If
the file does not exist, it is created.
-help Print a list of the pgxconfig command line options,
along with a brief explanation of each.
-i Start pgxconfig in interactive mode.
-prconf
Print the PGX32 (Raptor GFX) hardware configuration.

-propt
Print the current values of all PGX32 (Raptor GFX)
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 would be in the
OWconfig file after the call to pgxconfig would have
completed. The following is a typical display:
--- OpenWindows Configuration for /dev/fbs/gfxp0 ---
OWconfig: machine
Video Mode: not set
Depth: 8+24
-res video-mode [try | noconfirm | nocheck ]
Specify the built-in video mode used to drive the mon-
itor connected to the specified PGX32 (Raptor GFX)
device.
The format for video-mode can be one of the following:
widthxheightxrate
The width is the screen width in pixels, height
is the screen height in pixels, and rate is the
vertical frequency of the screen refresh. As a
convenience, -res also accepts formats with @
prepended to the refresh rate rather than x. For
example: 1280x1024@76. The list can be obtained
by running pgxconfig with the -res ? option (the
third form shown in the command synopsis above).
Note that not all resolutions are supported by
both the video board and by the monitor. The
pgxconfig utility will not permit you to set a
resolution not supported by the board unless the
noconfirm or nocheck option is specified. It
will also request confirmation before setting a
resolution not supported by the monitor if the
nocheck option is not specified.
Symbolic names
For convenience, the video modes listed below
have symbolic names defined. Rather than the
form widthxheightxrate, the symbolic name may be
supplied as the argument to -res. If the sym-
bolic name is none, the screen resolution will
be the video mode that is currently programmed
in the device when the window system is run.
svga 1024x768x60
1152 1152x900x76
1280 1280x1024x76
vga 640x480x60
none default console resolution
The -res option also accepts additional, optional
arguments immediately following the video mode specif-
ication. Any or all of these may be present.
noconfirm
Using the -res option, the user could put the
system into an unusable state, a state where
there is no video output. This can happen if
there is ambiguity in the monitor sense codes
for the particular code read. To reduce the
chance of this occurring, the default behavior
of pgxconfig is to print a warning message to
this effect and to prompt the user to find out
if it is okay to continue. The noconfirm option
instructs pgxconfig to bypass this confirmation
and to program the requested video mode anyway.
This option is useful when pgxconfig is being
run from a shell script.
nocheck
If present, normal error checking based on the
monitor sense code is suspended. The video mode
specified by the user will be accepted regard-
less of whether it is appropriate for the
currently attached monitor. (This option is use-
ful if a different monitor is to be connected to
the PGX32 (Raptor GFX) device). Use of this
option implies noconfirm as well.
try This option allows the user to test the speci-
fied resolution before committing it. It
displays a pattern on the screen with the speci-
fied resolution. If the test pattern appears
correctly, the user may answer "y" to the query.
The other permissable answer is "n".
-res ?
Print the list of possible resolutions supported by
the PGX32 and the monitor.
-24only
Force the PGX32 (Raptor GFX) device to use 24 bit only
when running Openwindows.
DEFAULTS
For a given invocation of pgxconfig, if an option does not
appear on the command line, the corresponding OWconfig
option is not updated; it retains its previous value, except
for -depth and -24only.
A default value is used if a PGX32 (Raptor GFX) option has
not been specified with pgxconfig when the window system is
run. The option defaults are as follows:
-dev /dev/fbs/gfxp0
-file system
-res none
The default of none for the -res option indicates that when
the window system is run, the screen resolution will be the
video mode that is currently programmed in the device.
EXAMPLES
Example 1: Switching the Resolution on the Monitor Type
The following example switches the monitor type to the reso-
lution of 1280 x 1024 at 76 Hz:
example# /usr/sbin/pgxconfig -res 1280x1024x76
