configuring an X Server on HP-UX Display subsection The Screen sections include one or more Display subsections. One Display subsection may be provided for each depth that the server supports. The size of the virtual screen may also be specified. The virtual screen allows you to have a "root window" larger than what can be displayed on the monitor. (e.g. the monitor may be a 800x600 display, but have a 1280x1024 virtual size). The Virtual keyword specifies this size. Note that many of the new accelerated graphics drivers use nondisplayed memory for caching. It is not desirable to use all available memory for the virtual display, as this leaves none for caching, and this can decrease server performance. Display subsections have the following format: SubSection "Display" Depth depth Visual visual Modes "ModeName" ViewPort x0 y0 Option... ... EndSubSection The Depth entry specifies what color depth the Display subsection is to be used for. Only Depths of 8 and 24 are supported. The Modes entry specifies the list of video modes to use. Each ModeName specified must be in double quotes. They must correspond to those specified or referenced in the appropriate Monitor section. The server deletes modes from this list which don't satisfy various requirements. The first valid mode in this list is the default display mode for startup. The list of valid modes is converted internally into a circular list. It is possible to switch to the next mode with Ctrl+Alt+Keypad-Plus and to the previous mode with Ctrl+Alt+Keypad-Minus. When this entry is omitted, the largest valid mode referenced by the appropriate Monitor section is used. The Visual entry is optional and sets the default root visual type. The only visual type available for depth 8 is: PseudoColor The only visual type available for depth 24 is: TrueColor The ViewPort entry is optional and sets the upper left corner of the initial display. This is only relevant when the virtual screen resolution is different from the resolution of the initial video mode. If this entry is not given, then the initial display is centered in the virtual display area. Option flags may be specified in the Display subsections. These may include driver-specific options or driver-independent options. The former are described in the driver-specific documentation. Some of the latter are described above in the Screen section, and they may also be included here. However, options set in the Display subsection may be "overridden" in the Screen section.

configuring an X Server on HP-UX
Display subsection
The
Screen
sections include one or more
Display
subsections. One Display subsection may be
provided for each depth that the server supports. The size of the virtual screen may also be
specified. The virtual screen allows you to have a “root window” larger than what can be
displayed on the monitor. (e.g. the monitor may be a 800x600 display, but have a 1280x1024
virtual size). The
Virtual
keyword specifies this size. Note that many of the new accelerated
graphics drivers use nondisplayed memory for caching. It is not desirable to use all available
memory for the virtual display, as this leaves none for caching, and this can decrease server
performance. Display subsections have the following format:
SubSection “Display”
Depth
depth
Visual
visual
Modes
“ModeName”
ViewPort
x0
y0
Option...
...
EndSubSection
The
Depth
entry specifies what color depth the Display subsection is to be used for. Only Depths
of 8 and 24 are supported.
The
Modes
entry specifies the list of video modes to use. Each
ModeName
specified must be in
double quotes. They must correspond to those specified or referenced in the appropriate
Monitor
section. The server deletes modes from this list which don't satisfy various requirements. The
first valid mode in this list is the default display mode for startup. The list of valid modes is
converted internally into a circular list. It is possible to switch to the next mode with
Ctrl+Alt+Keypad-Plus
and to the previous mode with
Ctrl+Alt+Keypad-Minus
. When this
entry is omitted, the largest valid mode referenced by the appropriate Monitor section is used.
The
Visual
entry is optional and sets the default root visual type.
The only visual type available for depth 8 is: PseudoColor
The only visual type available for depth 24 is: TrueColor
The
ViewPort
entry is optional and sets the upper left corner of the initial display. This is only
relevant when the virtual screen resolution is different from the resolution of the initial video
mode. If this entry is not given, then the initial display is centered in the virtual display area.
Option flags may be specified in the Display subsections. These may include driver-specific
options or driver-independent options. The former are described in the driver-specific
documentation. Some of the latter are described above in the Screen section, and they may also
be included here. However, options set in the Display subsection may be “overridden” in the
Screen section.
