Getting there

From X Manager, X Manager for Domains, or the X Administrative Console

(Administrative Console only) Click the Domain Definitions tab.
In the left pane, select an existing session definition or click next to Sessions Definitions to create a new one.
In the Session Definition pane on the right, click the Extensions tab.

Available Extensions

The following server-side extensions are available in Reflection X Advantage.

Damage	Allows applications to be notified of the regions of windows and pixmaps that are changed by rendering.
GP MIT Shared Memory	Required by certain applications. Reflection X Advantage does not support any functional capabilities of this extension. However, its presence allows these applications to operate.
GLX	Select and configure to run interactive X client applications that produce still or animated three-dimensional color objects, with shading, lighting, and other effects. See GLX Extension Options for more information. NOTE: GLX is the OpenGL extension to the X Window System; OpenGL is an industry-standard three-dimensional graphics API. Support for GLX requires access to an OpenGL implementation that supports Pbuffers.
MIT Shared Memory	Required by certain applications. Reflection X Advantage does not support any functional capabilities of this extension. However, its presence allows these applications to operate.
MIT Sundry	Permits an application to query and change the server setting that controls tolerance of old (version X11R3) X protocol bugs. The server setting applies to all applications. It is typically safe to leave this extension enabled.
Render	Select and configure to use the three-dimensional graphics capabilities of newer video cards. This extension allows applications to use features such as anti-aliased fonts, drop shadows, and translucency. See Render Extension Options for more information.
Shape	Used to create and manipulate non-rectangular windows. Some applications do not appear correctly when this extension is disabled.
Sync	Synchronizes clients on different hosts running different operating systems. Support of this standard is important for multimedia applications, where audio, video, and graphics data streams are being synchronized. The extension also provides internal timers within the X server to which client requests can be synchronized, allowing simple animation applications to be implemented without any round-trip requests and making the best use of buffering within the client, network, and server.
X Big Request	Enables an application to send protocol requests that exceed 262,140 bytes in length.
X Direct Access	Required by certain applications. Reflection X Advantage does not support any functional capabilities of this extension. However, its presence allows these applications to operate.
X Fixes	Supports notification of selection changes, tracking and naming of cursor images, and region objects. Also improves the reliability of embedded applications. The Damage extension uses the region object support of this extension.
XFree86 Big Font	Removes duplicate font metric (size) data for large fonts. This compresses QueryFont replies and reduces the amount of memory used for displaying large fonts.
X Input	Allows X clients to use the X Input extension APIs to query, change, and modify the core input devices (mouse and keyboard).
X Test	Allows an application to test the X server automatically, with no user intervention, primarily by allowing synthesis of input device events. NOTE:It is typically safe to leave this extension enabled. However, it is only required by automated test applications.
