when using 24 bits per pixel both
DirectColor
and
TrueColor
can be used. At 8 bits per
pixel, all visual types are available.
The default visual types are:
TrueColor
for 16 and 24 bits per pixel, and
PsuedoColor
for 8
bits per pixel.
For information on changing the default visual, see
“Overriding the Default Settings” (page 16)
.
Open3D Support
The HP PCI AMD Radeon 7000 Graphics Adapter is not supported for 3D graphics.
Multiple Graphics Cards Support
The HP PCI AMD Radeon 7000 Graphics Adapter software has been tested for up to four (4)
cards per system. All operations are supported on every card in the system. Consult your Integrity
system options documentation for detailed information on number of cards supported and
configuration limitations.
The embedded graphics available on most HP Integrity systems that are based on the HP PCI
AMD Radeon 7000 Graphics Adapter and AMD RN50 are compatible with multi-headed
operation.
Multi-Screen Versus XINERAMA
By default, multiple screens are handled as traditional X11 multiple screens. However, the screens
can be handled as a single “virtual” screen using the XINERAMA extension. This is documented
in two (2) places:
•
in the
DECW$PRIVATE_SERVER_SETUP.COM
procedure.
•
in the Motif documentation.
Screen Order and Forcing Single Headed Operation
Screen order is determined by the bus ordering of devices, and will vary across platforms. The
DECW$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 this line:
$ DEFINE/SYSTEM/NOLOG DECW$PRIMARY_DEVICE_"GHB0"
Modifying the Graphics Configuration
The following sections describe graphic configuration settings.
HP PCI AMD Radeon 7000 Graphics Adapter Default Graphics Settings
The default graphics resolution is 1024 x 768. The default refresh rate is 70Hz. 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 HP OpenVMS I64, enter these commands in the following
order at the
DCL
prompt:
$ @decw$utils:decw$define_utils
$ xdpyinfo
In addition, you can show the following logical names at the
