1.8.2.2 Device Option Examples

This section provides examples of stacked and side-by-side dual-monitor arrangements.

In all examples, the order of the devices is important. The first device specified must be the screen physically placed to the left or top of the second device. The second device specified must be the screen physically placed to the right or bottom of the first device.

[ left ] [ right ]

The following command line instructs the system to start up two displays. The left display is the default frame buffer and the right display is a monochrome. This enables you to move the cursor left and right between the two displays.

$ openwin -dev /dev/fb left -dev /dev/fbs/bwtwo0 right

The following example is equivalent to the previous example. By default, the first device is to the left of the second device listed in the command line.

$ openwin -dev /dev/fb -dev /dev/fbs/bwtwo0

The following command line instructs the system to start up two displays. The right display is the default frame buffer and the left display is a monochrome. This setup enables you to move the cursor left and right between the two displays.

$ openwin -dev /dev/fb right -dev /dev/fbs/bwtwo0 left

[ top ] [ bottom ]

The following command line instructs the system to start up two displays. The top display is a CG6 and the bottom display is a monochrome. This setup enables you to move the cursor up and down between the two displays.

$  openwin -dev /dev/fbs/cgsix0 top -dev /dev/fbs/bwtwo0 bottom

The following example is not equivalent to the previous example. By default, the first device is to the left of the second device listed in the command line.

$   openwin -dev /dev/fbs/cgsix0 -dev /dev/fbs/bwtwo0

The following command line instructs the server to start up two displays. The bottom display is a CG6 and the top display is a monochrome. This setup enables you to move the cursor up and down between the two displays.

$  openwin -dev /dev/fbs/cgsix0 bottom -dev /dev/fbs/bwtwo0 top
