HP 7500 I Modifying the Graphics Configuration, Screen Order and Forcing Single Headed Operation

Screen Order and Forcing Single Headed Operation

Screen order is determined by the bus ordering of devices, and will vary across platforms. The

DECW$PRIVATE_SERVER_SETUP.COM file allows the user to override the ordering of screens, or to force single headed operation. See the documentation in the file, and in the Motif documentation for more information. For example, to force a specific graphics option to be used in single head mode (in this case GHB0), add the line:

$ DEFINE/SYSTEM/NOLOG DECW$PRIMARY_DEVICE “GHB0”

Modifying the Graphics Configuration

ATI RADEON 7500 Default Graphics Settings

The default graphics resolution is 1024 x 768. The default refresh rate is 70 Hz. The default pixel depth is 24 bits per pixel and the default visual type is TrueColor.

Determining Current Settings

To find the current settings under OpenVMS, issue the following 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$SERVER* DECW$XSIZE_IN_PIXELS $ SHOW LOGICAL/TABLE=DECW$SERVER* DECW$YSIZE_IN_PIXELS

$ SHOW LOGICAL/TAB=DECW$SERVER* DECW$SERVER_DEFAULT_VISUAL_CLASS

If any logical name is not defined, then the respective default is in effect.

You can also confirm the settings and any errors in the setup by examining the server error log file:

$ TYPE SYS$MANAGER:DECW$SERVER_0_ERROR.LOG

Overriding the Default Settings

The SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.COM procedure contains documentation for many of the default X11 server settings that may be changed. For more information on making changes to the default settings, symbols, and system-wide logical names, refer to the manual titled Managing DECwindows Motif for OpenVMS Systems. An online version of this document is available at:

A complete list of available DECwindows Motif V1.3-1 documentation is available at:

For newer releases of documentation, check the main HP OpenVMS Systems Documentation site at:

OpenVMS Alpha and I64 use the same implementation of X11 and Motif and documentation for one generally applies to the other, unless otherwise noted.
