1 Introduction to HP Remote Graphics

Software

This guide provides information that you will need to install, configure, and use HP Remote Graphics

Software (RGS). RGS enables you to view and interact with the desktop of a remote computer over a

standard TCP/IP computer network.

HP Remote Graphics Software (RGS) is a high-performance remote desktop connection protocol that

delivers an exceptional remote desktop user experience for rich user environments that include video,

web flash animations and graphics intensive applications. All applications run natively on the remote

system and take full advantage of the compute and hardware graphics resources of the sending system.

RGS captures the desktop of the remote system and transmits it over a standard network to a window

on a local client using advanced image compression technology specifically designed for text, digital

imagery and high frame rate video applications. A local hardware keyboard and mouse is supported

as well as USB device redirection to provide an interactive, high performance, multi-display desktop

experience.

RGS supports a broad range of client virtualization technologies including multi-user virtual desktop

infrastructure (VDI) solutions, blade workstations, desktop PCs, mobile PCs, and workstations.

This guide is organized as follows:

Chapter 1:

Introduction to HP Remote Graphics Software on page 1—This chapter provides an

introduction to RGS, describing a typical RGS configuration, and the roles of the Local and Remote

Computers. This chapter also describes the primary features of RGS.

Chapter 2:

RGS overview on page 9—This chapter gives an overview of the RGS capabilities,

including the supported computers and operating systems, RGS connection topologies, multi-monitor

configurations, remote USB, and remote audio.

Chapter 3:

Installing RGS on page 52—Installation of the RGS Sender and Receiver is described in

this chapter.

Chapter 4:

Pre-connection checklist on page 91—Establishing an RGS connection from a Receiver

to a Sender requires that the Local and Remote Computers be in the correct state. This chapter provides

a checklist of items that should be verified before attempting an RGS connection.

Chapter 5:

Using RGS on page 100—This chapter describes how to use RGS. Establishing a

connection from the Local Computer to the Remote Computer in Normal Mode is described, including

the different login methods. Features such as collaboration are also described.

Chapter 6: Advanced capabilities on page 118—This chapter describes the RGS advanced

capabilities that are provided by each of the tabs in the Receiver Control Panel.

Chapter 7:

Using Directory Mode on page 170—Establishing RGS connections using Directory

Mode is described in this chapter.

Chapter 8:

RGS properties on page 174—This chapter describes each of the RGS Sender and

Receiver properties.

Chapter 9:

Sender event logging on Windows on page 206—This chapter describes the Windows

Event Logging capability of RGS.

Chapter 10:

Remote Application Termination on page 211—This chapter describes how the

Windows Event Logging capability of RGS can be used to terminate applications if a desktop session is

left running without supervision.

Chapter 11:

Optimizing RGS performance on page 227—This chapter provides a number of

suggestions to optimize RGS performance.

Chapter 12:

Troubleshooting RGS on page 231—This chapter describes how to troubleshoot issues

related to establishing an RGS connection, network timeouts, graphics performance, remote audio, and

remote USB.

Chapter 13:

RGS error messages on page 232—This chapter lists each of the errors reported by the

RGS Receiver and describes their probable cause.

Appendix A:

Linux remote audio device support on page 235—This appendix provides information

on audio devices that are supported on Linux-based Remote Computers.

Typical RGS configuration

The following illustration shows a typical RGS configuration, consisting of a remote computer (sender)

and a local computer (receiver). In this example, the sender is the personal workstation on the left and

the receiver is the mobile workstation on the right. The user’s applications run on the sender while the

user interacts with these applications from the receiver.

Figure 1-1 Typical RGS configuration

The workstation image is transmitted over the network to the receiver, which displays the desktop image

locally in a window. RGS is designed to provide fast capture, compression, and transmission of the

desktop image over standard TCP/IP networks. RGS also captures user keyboard and mouse inputs

from the client and sends them over the network to the sender.

RGS also supports remote USB, which enables a user to connect USB devices to the receiver and have

the USB devices accessible by the sender. In addition, RGS supports remote audio, whereby audio

output from the applications is transported over the network for playback on the receiver.

RGS Sender and Receiver

Figure 1-2 RGS Sender and Receiver on page 4 shows the two primary RGS software components,

the RGS Sender and RGS Receiver. The RGS Sender runs on the Remote Computer while the RGS

Receiver runs on the Local Computer.

Figure 1-2 RGS Sender and Receiver

The Sender and Receiver provide the following functionality:

●

Sender—Runs on the Remote Computer, and transmits graphics updates, audio, and USB data to

the RGS Receiver on the Local Computer. The RGS Sender receives and processes keyboard

events, mouse events, and USB data from the Receiver.

●

Receiver—Runs on the Local Computer. The RGS Receiver establishes a connection to the Remote

Computer, requests graphics updates from the Remote Computer Sender, and displays the desktop

of the Remote Computer inside a window on the Local Computer. The RGS Receiver transmits

keyboard and mouse events to the RGS Sender.

The RGS Sender captures the actual screen pixels that are generated by the graphics adapter on the

Remote Computer. This process is often referred to as screen scraping, and operates independently of

whether or not a monitor is actually connected to the Remote Computer.

NOTE: Local user refers to the person physically located at the Local Computer. Remote user refers to

the person physically located at the Remote Computer (if, in fact, a person is present at the Remote

Computer).

A local user who establishes an RGS login to the Remote Computer is known as the primary user. Once

a primary user has been established, another local user can view the Remote Computer desktop session

using RGS only if allowed by the primary user. There are situations, however, where a local user may

replace the previous primary user and become the new primary user.

The process by which a local user can become a primary user or view the primary user’s desktop is

described in detail in this guide.
