Scenario 1: All receiving computers have the same configuration

If all receiving computers have the same configuration, then using the Virtual entry under the Screen section

of the file xorg.conf is the easiest method.

For example, if all receiving computers have four monitors configured at 1280x1024 each, configure the X

server to run at a resolution of 5120x1024 by making the following additions to the file xorg.conf.

Add the following under the Device section:

Option "UseDisplayDevice" "none"

Option "UseEDID" "false"

Add the following under the Screen section:

SubSection "Display"

Virtual 5120 1024

Depth 24

EndSubSection

Now, every time you connect via RGS, the X server is configured to have a single screen running at a

resolution of 5120x1024, which covers all four of the receiving computer’s monitors. You can use this

method to support a very large virtual display limited only by frame buffer memory.

Scenario 2: Receiving computers have different configurations

In the more likely scenario where you need to support many different display resolution and monitor

configurations, you can use the NVIDIA TwinView mode to match the resolutions. TwinView mode is where

two display devices (digital flat panels, CRTs) can display the contents of a single X screen in different

configurations. This method for using multiple monitors has the following distinct advantages over other

techniques such as Xinerama (which is not supported by RGS):

●

It uses only a single X screen. The NVIDIA driver conceals all information about multiple display devices

from the X server. As far as the X server is concerned, there is only one screen.

●

Both display devices share one frame buffer. Thus, all the capabilities present on a single display (for

example, accelerated OpenGL) are available with TwinView.

●

There is no additional overhead when emulating a single desktop.

For example, if all receiving computers have either single or dual monitors, you should configure the X server

to think it has the monitor with the highest resolution used on any of the receiving computers. This allows

the X server to support as many display resolutions as possible. You do this by capturing the EDID

information from the monitor (see

Creating an EDID file on Linux on page 51) and making the following

additions to the file xorg.conf.

NOTE: This example uses dual HP LP2465 displays.

Add the following under the Device section:

Option "ConnectedMonitor" "DFP-0,DFP-1"

Option "CustomEDID" "DFP-0:/etc/X11/lp2465edid.bin;DFP-1:/etc/X11/

lp2465edid.bin"

Now that the X server thinks it has dual HP LP2465 displays attached to it, enable TwinView support and

configure the supported single and dual display layouts under the Screen section:

Option "TwinView" "True"
