Exceed onDemand 5 — A Technical Whitepaper Figure 10 — Use Xkeys tool to create or modify keyboard mapping files Screen Settings Screen settings are not only user preference settings; they are also application preference settings. X applications may require the X server to be set up in a particular way in order for the application to function properly. Screen settings are mainly comprised of the configuration for the Server Visual and Window Mode. Server Visual Server Visual defines the color characteristics for the specified screen of the X server display. The Server Visual is crucial to the successful execution of an X application because it defines the colors that are available to an X application. It also determines the ability of the X application to change the color maps based on the application’s requirements. Exceed onDemand offers 5 different Server Visuals and an option to allow Exceed onDemand Server to automatically select the most appropriate Server Visual based on the Windows desktop color depth. Under most circumstances, users should let Exceed onDemand detect and select the Server Visual that is most appropriate for the current X session. However, some X applications demand a specific Server Visual that is not obvious to Exceed onDemand’s detection mechanism. Failing to comply will result in an unsuccessful execution of the application, or it will be executed with poor visual quality. In this case, users should override the Server Visual setting. Exceed onDemand also supports multiple server visuals and multiple color depths, which is required by some advanced X applications. 32
Figure 11 — Select a server visual for the session Window Mode Exceed onDemand supports two window modes: > Multiple Window Mode — Displays each X application in a separate window > Exceed onDemand 5 — A Technical Whitepaper > Single Window Mode — Displays all X applications in a single Exceed onDemand window For users who want the most seamless integration of UNIX and Windows work environments, Multiple Window Mode will be the most desirable choice — X applications will be wrapped by Native (Microsoft) Window Manager by default and blend in nicely to the Microsoft Windows desktop. Other X applications may require support for a different window manager, such as Motif Window Manager, so Exceed onDemand allows users to change the Window manager from Native to any X window manager of their choice. Users who want a consolidated view of all X applications in a single window can easily change the window mode to Single with just the toggle of a switch. Users are required to launch an X window manager to manage all the X applications. 33
