Compaq Tru64 UNIX Configuration 3-1
3.2 Restrictions and Limitations
This section of the document contains limitations and restrictions of the
OXYGEN VX1 hardware and software.
3.2.1 Minimum Console Revision
The minimum Tru64 UNIX firmware version for 3Dlabs OXYGEN VX1 PCI
graphics controller single head support is V5.8 (V5.9 for multihead
configurations – see Section 3.4).
3.2.2 Multiple Colormaps
Multiple colormaps are not supported. The 3Dlabs OXYGEN VX1 PCI graphics
controller supports only one installed colormap at one time. Exceeding this limit
will cause colormap flashing, also known as "technicolor."
Applications should not install or deinstall colormaps themselves. The window
manager should perform these actions. However, the application is responsible
for providing the window manager with hints as to which colormaps to install or
deinstall. You provide this information using the Xlib function
XSetWMColormapWindows(). This function sets the WM_COLORMAP_WINDOWS
property for a given window.
3.2.3 Default Visual Information
The 3Dlabs OXYGEN VX1 board can only support one visual type at one time.
Supported visual types are 8-bit PseudoColor, 16-bit TrueColor, and 24-bit
TrueColor. By default, the default depth and visual class is 8-bit PseudoColor.
To change the default visual, you must edit the X server's configuration file
which is located at /usr/var/X11/Xserver.conf.
As an example, to switch to 24-bit TrueColor:
! Permedia VX1 Server args start
-pn -bs -su -nice -2 -depth 24 -vclass TrueColor
! Permedia VX1 Server args end
You then need to restart the X server. When logged in remotely:
/usr/sbin/init.d/xlogin restart
3-2 3Dlabs OXYGEN VX1 PCI Graphics Controller Installation Guide
3.2.4 Backing Store and Save Unders
By default, backing store and save unders are enabled. If the default visual
depth is changed to 16 or 24, it is recommended that backing store and save
unders be disabled.
To disable these features, add the options "-bs -su" to the argument list in
the X server’s configuration file. Refer to the example in Section 3.2.3.
3.3 Configuring Graphics Resolution or Vertical
Refresh Rate for Tru64 UNIX
There are two X server related files that can be used to configure or change
characteristics of the X server. Systems by default use a file named "Xservers"
to start and optionally pass startup configuration parameters to the Xserver.
3.3.1 Current Graphics Resolution
The graphics Resolution and Refresh Rate is set at the default value, 1024x768
at 70Hz Refresh Rate. The graphics resolution of a running system can be
obtained by executing the command /usr/sbin/sizer -gr. The Refresh Rate may
be obtained from the X servers file /var/dt/Xservers.
3.3.2 Changing the Resolution & Refresh Rate Using the
Xservers File
The steps necessary to change the X servers graphics resolution differ
depending on which X Windowing System is in use, XDM/Motif or the newer
standard CDE (Common Desktop Environment). UNIX systems running
version 4.0F, and G can use either the XDM/Motif or CDE GUIs.
If your system is running version 4.0F, or G, you must determine which GUI
in use for the system and then proceed to the appropriate section of this
document, "How to Change the Resolution and Refresh Rate on XDM GUI" or
"How to Change the Resolution and Refresh Rate on CDE GUI".
Systems running UNIX versions 5.0 or higher can use only the CDE GUI, so
you may skip directly to "How to Change the Resolution and Refresh Rate on
CDE GUI".
Compaq Tru64 UNIX Configuration 3-3
is
3.3.3 How to Determine which GUI is in Use
1. Check the environment variable XLOGIN defined in the file /etc/rc.config.
Example (showing the CDE GUI being used):
# /usr/sbin/rcmgr get XLOGIN
cde
#
1. If the variable is defined to be "cde," then the default GUI is CDE. If the
variable is defined to be "xdm," then the default GUI is XDM/Motif.
How to Change the Resolution and Refresh Rate on XDM GUI
1. Log in to the system as "root".
2. Make a backup copy of the file /usr/lib/X11/xdm/Xservers .
Example:
# cp /usr/lib/X11/xdm/Xservers /usr/lib/X11/xdm/Xservers.original
3. Edit the file /usr/lib/X11/xdm/Xservers and add the appropriate X
server Option, "-screen0" and or "-vsync0" to the line that starts the X
server. This line is generally the last line in the file Xservers.
Example line from the Xservers file used with XDM/Motif.
:0 local /usr/bin/X11/X
Or
:0 local /usr/bin/X11/X -nice -2
X server Options:
-screen[screen] WxH
Set screen (W)width and (H)height.
-vsync[screen] Hz
Set screen (Hz) Vertical refresh rate
3-4 3Dlabs OXYGEN VX1 PCI Graphics Controller Installation Guide
___________________________Note ____________________________
• These are device dependent X server options and not available for ALL graphics
options. Please refer to Table 3–1 for supported Resolutions and Refresh Rates.
• Both the Width and Height should be specified in the "-screen" option and not just
the Width. On some X server graphics devices setting ONLY the Width will cause
the X server to fail.
• The [screen] number need not be specified if only one screen exists or if the user
wants all screens to use the same values. The [screen] value is generally '0' as
shown in the example below.
Example:
-screen0 1280x1024
^
|_ [screen] value
• Anything added after the "-I" option will be ignored by the X server and passed on
to the DDX, Device Dependent X layer of the server. The "-screen" and or "vsync" option(s) should precede the "-I" option.
____________________________________________________________
4. Restart the GUI using the appropriate method.
For DIGITAL UNIX V4.* systems use:
# /sbin/init.d/xlogin stop
# /sbin/init.d/xlogin start
How to Change the Resolution and Refresh Rate on CDE GUI
1. Log in to the system as "root".
2. Check to see if the directory /etc/dt/config exists. If not, create it as follows:
Example:
# mkdir /etc/dt/config
# chmod 755 /etc/dt/config
3. Copy the Xservers file from the path /usr/dt/config to the path
/etc/dt/config.
Example:
# cp /usr/dt/config/Xservers /etc/dt/config/Xservers
Compaq Tru64 UNIX Configuration 3-5
4. Edit the file /etc/dt/config/Xservers and add the appropriate X server
Option, "-screen0" and or "-vsync0" to the line that starts the X server. This
line is generally the last line in the file Xservers.
Example line from the Xservers file used with CDE:
:0 Local local@console /usr/bin/X11/X :0 -screen0 1280x1024
X server Options:
Set screen (W)width and (H)height.
-screen[screen] WxH
Set screen (Hz) Vertical refresh rate
-vsync[screen] Hz
___________________________Note ____________________________
• These are device dependent X server options and not available for ALL graphics
options. See Table 3–1 for supported Resolutions and Refresh Rates.
• Both the Width and Height should be specified in the "-screen" option and not just
the Width. On some X server graphics devices setting ONLY the Width will cause
the X server to fail.
• The [screen] number need not be specified if only one screen exists or if the user
wants all screens to use the same values. The [screen] value is generally '0' as
shown in the example below.
Example:
-screen0 1280x1024
^
| [screen] value
• Anything added after the "-I" option will be ignored by the X server and passed on
to the DDX, Device Dependent X layer of the server. The "-screen" and or "vsync" option(s) should precede the "-I" option.
____________________________________________________________
5. Restart the CDE GUI.
For DIGITAL UNIX V5.* systems use:
# /sbin/init.d/xlogin stop
# /sbin/init.d/xlogin start
Examples of Typical Resolution and Refresh Rate Settings Using CDE
• Setting the Screen Resolution to 1280 x 1024.
:0 Local local@console /usr/bin/X11/X :0 -screen0 1280x1024
3-6 3Dlabs OXYGEN VX1 PCI Graphics Controller Installation Guide
• Setting the Screen Resolution to 1280 x 1024 and the Vertical Refresh
Rate to 75Hz.
:0 Local local@console /usr/bin/X11/X :0 -screen0 1280x1024 -vsync0 75
• Setting the Screen Resolution to 1920 x 1080 and the Vertical Refresh
Rate to 70Hz.
:0 Local local@console /usr/bin/X11/X :0 -screen0 1920x1080 -vsync0 70
3.4 Multihead Support
The minimum firmware version for multihead 3Dlabs OXYGEN VX1 PCI
graphics controller support on AlphaServer and AlphaStation DS10, DS10L,
DS20E, and ES40 is V5.9. The Alpha system firmware must be updated to
support 3Dlabs OXYGEN VX1 PCI graphics controllers. Once the Alpha system
firmware has been updated, multiple 3Dlabs OXYGEN VX1 PCI graphics
controllers may reside in the same system.
___________________________Note ____________________________
Only one 3Dlabs OXYGEN VX1 PCI graphics controller will be used for the VGA console;
it must be placed on the primary PCI bus.
____________________________________________________________
The card in the lowest numbered slot will usually be selected to be the VGA
console. See your workstation or server user manual to determine slot
numbering. The maximum number of 3Dlabs OXYGEN VX1 PCI graphics
controllers supported by software is 16, but please see the following section for
limitations.
3.4.1 Multihead Restrictions and Limitations
The 3Dlabs OXYGEN VX1 PCI graphics controller is not supported in
conjunction with any other non-3Dlabs OXYGEN VX1 PCI graphics controller
residing in the same system.
All 3Dlabs OXYGEN VX1 PCI graphics controllers in a single system must have
the same color depth. The supported number and configuration of multiple
3Dlabs OXYGEN VX1 PCI graphics controllers varies by platform. Other
documentation shipped with your workstation or server will outline specific
limitations on the actual number and the configuration of multihead support.
Compaq Tru64 UNIX Configuration 3-7
3.4.2 Matching X Server Primary Screen with VGA Console
PCI slots are not always probed by the system in the order of their slot
numbers. Because of this, the order of X server screens will not necessarily
correspond to the order of the slots in which the 3Dlabs OXYGEN VX1 PCI
graphics controllers reside. The X server command line option -screenOrder
may be used to alter the mapping of physical screens to logical screens. In
particular, this can be useful if you desire the X server’s primary screen to
coincide with the VGA console.
3.5 Messages
Device driver messages are typically logged to /var/adm/messages on Tru64
UNIX systems. Should problems arise, this file should be checked for
informational messages; an example is shown here.
• p3g: %dx%d cursor glyph truncated to hardware limits
The X Server attempted to use a cursor larger than the
64x64 limits of the hardware. Cursor glyph will be
displayed incorrectly. Application should be brought
into conformance with X11 expectations.

The modes available are dependent on monitor capabilities. In general, refresh
rates below 70 Hz are discouraged, as they tend to show flicker based on the
lighting source and surrounding equipment.
The available resolution is monitor dependent. All heads must have the same
pixel depth. The pixel depth default is 8 bits per pixel.

4.4 Default Graphics Settings
The default graphics resolution is 1024 x 768. The default refresh rate is 70 Hz
and the default color depth is 8 bits per pixel.
4.5 Determining Current Settings
To find the current settings under OpenVMS, issue the following two
commands, in order, at the DCL prompt:
$ @DECW$UTILS:DECW$DEFINE_UTILS
$ XDPYINFO
In addition, you can show the following logical names at the DCL prompt:
$ SHOW LOGICAL/SYSTEM DECW$SERVER PIXEL_DEPTH
$ SHOW LOGICAL/SYSTEM DECW$SERVER REFRESH_RATE
$ SHOW LOGICAL/TABLE=DECW$SERVER* *SIZE_IN_PIXELS
If any of these logicals is not defined, then the respective default is in effect (see
Section 4.4).
Alternatively, you can also view the following error log file to determine the
current settings:
$ TYPE SYS$MANAGER:DECW$SERVER_0_ERROR.LOG
4.6 Overriding Default Settings
To override any of the default settings, follow these steps:
1. Copy or rename the
SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.TEMPLATE file to
create a new command (.com) file called
DECW$PRIVATE_SERVER_SETUP.COM.
2. Now make the edits for the settings you want to change using a text editor,
and save the file.
4-4 3Dlabs OXYGEN VX1 PCI Graphics Controller Installation Guide
3. For the changes to take effect immediately you must restart the X server so
that the new command file and changed settings will be used. The
command to do this is as follows:
$ @SYS$MANAGER:DECW$STARTUP RESTART
The new file settings will now override the original default settings.
The DECW$PRIVATE_SERVER_SETUP procedure contains documentation for
many of the default X server settings which may be changed. For more
information on making changes to the default settings, symbols, and systemwide logicals, refer to the manual titled Managing DECwindows Motif for
OpenVMS Systems. This document describes the symbols and settings that can
be changed in the DECW$PRIVATE_SERVER_SETUP.COM file. For a copy of
the document, contact your local sales support representative or visit the
Compaq web site located at http://www.compaq.com.
Additional system logicals are described in
SYS$MANAGER:DECW$DEVICE_CONFIG_GF.COM.
However, this file should not be modified. If you wish to make changes to the
default logicals defined within it, redefine them in the
DECW$PRIVATE_SERVER_SETUP.COM file. These changes will supersede
the logicals assigned in the device configuration file.
Some of the items that you can change via system logicals are described in the
device configuration file but are not normally defined in
DECW$PRIVATE_SERVER_SETUP.COM file. Those logical default settings
not defined in that file but that can be changed include the following items:
DECW$XSIZE_IN_PIXELS
DECW$YSIZE_IN_PIXELS
DECW$SERVER_REFRESH_RATE
DECW$SERVER_PIXEL_DEPTH
4.7 Multihead Support
Multiple 3Dlabs OXYGEN VX1 PCI graphics controllers may reside on the same
system. However, only one will be used for the VGA console.
The supported number and configuration of multiple 3Dlabs OXYGEN VX1 PCI
graphics controllers varies by platform. OpenVMS can support up to four
devices on a single system. The actual maximum is a combination of the
Compaq OpenVMS Software Installation and Customization 4-5
number of slots available and the number of heads (graphics modules) qualified
for each of the platforms. Other software may put additional restrictions on the
number of units supported.
Other documentation shipped with your workstation or server may put specific
limitations on the number and configurations for multihead support. Therefore,
you should refer to the appropriate documentation set for limitations or
exclusions that are appropriate to your situation.
The 3Dlabs OXYGEN VX1 PCI graphics controller is not supported in
conjunction with any other graphics board residing in the same system.
4.7.1 Matching Primary Screen with VGA Console
Screen 0 is always the VGA-enabled head and must be installed in the lowest
numbered slot of all installed graphics cards and must be placed on the PCI bus
containing the ISA bridge. If you wish to change a screen with any of the
console displays, you can alter the logical order for mapping of physical screens
to logical screens by making a copy of the file
DECW$PRIVATE_SERVER_SETUP.TEMPLATE and saving it to a new file
named DECW$PRIVATE_SERVER_SETUP.COM. You can then make changes
to the default settings by editing the newly created file. Refer to Section 4.6 for
details on changing the default settings.
Caution: Changing the default settings in the
DECW$PRIVATE_SERVER_SETUP.COM file to try matching a screen with a
console display can have unanticipated and adverse consequences. You should
attempt to perform this operation only if you fully understand all possible
consequences including the chance for loss of your primary screen.
4.8 Messages
Server messages are typically logged to the DECW$SERVER_0_ERROR.LOG file
located in the SYS$MANAGER directory. Be sure to check this file first for
informational messages related to any problems that are encountered during
installation or usage.

4.9 POLYCENTER Software Installation
At the end of the OpenVMS POLYCENTER Software Installation procedure, a
message is displayed that recommends a reboot of the system. At the conclusion
of the installation, the POLYCENTER Software Installation utility does not
prompt for or enforce a reboot of the system for the new software image to
become effective immediately. The 3Dlabs OXYGEN VX1 PCI graphics
controller two-dimensional (2D) support software becomes active only after the
operating system has been rebooted.
If the software is being installed in a clustered environment and it is not
convenient to perform a reboot immediately following installation, then a rolling
reboot may be used for the new image to take effect across all systems.
