A system providing multiple virtual screens that are associated with one or more display elements in a server within an "X Window" system environment. Only the server within this environment has knowledge that the multiple virtual screens are not multiple hardware frame buffers that serve one or more display elements. The user of the server may change from one virtual screen to another virtual screen in various ways. Since the "X Window" client process is unaware that there are multiple virtual screens, the client sends data to a screen assuming that it is a separate "X Window" screen. When this data is received, the server displays the data only if the particular virtual screen is currently selected for display.
