It is also
the preferred configuration of some vision-impaired users, who need a low display
resolution but like a large desktop size.
By default, the virtual screen size is the largest size specified in the Modes entry,
which works with the hardware. The virtual screen size is reported in the log file
(Section 3.15).
Note that a Modes entry does not have to list the highest resolution as the first
(default) entry. The virtual screen size will be set to resolution of the largest valid
mode.
Alternately, you can specify a specific virtual screen size in the Display subsection:
Virtual 2048 1536
Viewport 0 0
The Virtual entry specifies the size of the virtual screen in pixels. In this example,
we??™re configuring a huge 3-megapixel virtual screen. Any display modes larger than
the specified size will be disabled (unlikely in this case!).
The Viewport entry specifies the starting point of the upper-left corner of the
physical screen within the virtual screen; the value of 0 0 given here will position
the physical screen in the upper-left corner of the virtual screen. The default is to
show the center of the virtual screen, but that??™s not always the best choice, since
desktop menus and panels are usually displayed on the edge of the screen so the
initial display may look deceptively empty.
