So when is each mode useful?
Xinerama is probably the best bet if you??™re using multiple screens just to get more
real estate??”for example, if you have multiple monitors side-by-side on a desk or
arranged with monitor arms or frames in a rectangular array.
Multi-screen operation is a good choice when the screens serve different purposes,
such as when one screen is connected to a projector and the other is used for display
management, or one screen is used for a customer-facing point-of-sale display and
the other is used for a staff-facing display.
4.4 Positioning Screens
If you have two or more monitors, you can place them one above the other, side by
side, or diagonally. Even a simple side-by-side arrangement can take different forms,
especially when the monitors are different sizes: do the tops of the monitors line up,
or the bottoms? Or is the side of the smaller monitor centered at the side of the larger
monitor?
Figure 4-2 illustrates a few of the many possibilities for two monitors of different
sizes.
You can use three different methods to describe position information in Screen
entries within a ServerLayout section:
??? You can use an absolute X-Y pixel position within the Xinerama screen.
