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 800x600
display, but have a 1280x1024 virtual size). The
Virtual
keyword is used
to specify this size. Note that many of the new accelerated graphics
drivers use non-displayed 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 ìDisplayî
Depth
depth
Visual
visual
Modes
ìModeNameî
ViewPort
x0
y0
Option Ö
...
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 will delete modes from this list which don't satisfy various
requirements. The first valid mode in this list will be 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 will be used.
The
Visual
entry is optional and sets the default root visual type.
The visual type available for the depth 8 is: PseudoColor
The visual type available for depth 24 is: TrueColor
The
ViewPort
optional entry 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 will be centered in the virtual display area.
