This section describes the options for window modes: Multiple Window, Single Window, Other.
The following illustration shows the default settings for the Window modes. which includes Multiple Window and Single Window..
The one exception is for the XDMCP connection - for XDCMP, only Single Window Mode is available.
Multiple Window mode provides a separate window for each session. This window mode is recommended.
The one exception is XDMCP connection in that case, Single Window is automatically selected and Multiple Window is not an option. However, XDMCP connections can be displayed on specific monitor(s). For more information, see Spanning Monitors in the following section.
Single Window mode is automatically selected when the XDMCP connection method is used. To view the desktop of the local workstation, the size of the Single Window can be adjusted. For more information, see Single Window.
Additionally, a remote window manager or desktop (such as twm, open look, motif, CDE, HP-VUE, etc.) may be run in the Single window mode. These window managers need to take over the whole screen to provide the user's preferred look. To accommodate these window managers, the X server has the Single window mode, which gives the window manager (and the X-applications) a virtual root window, which looks to the window manager like a separate X-terminal.
Only advanced users should specify Single Window as the default mode.
Check this box if you would like the X-Win32 single window to extend itself over all the monitors connected to your system. This options only has an effect if you have multiple monitors connected to your Windows Machine.
The maximum number of monitors is dependent on the local workstation and its Windows operating system. Windows provides the numerical identification of each monitor, which can be viewed as follows:
The following example is for Windows XP. The display for other operating systems may vary.
Right-click the desktop (display) of your monitor.
In the drop menu, select Properties.
In the Display Properties window, select the settings tab.
The available monitors will be displayed.
By default, X-Win32 uses the RANDR extension to resize a single window. This extension will resize and shrink or expand the window. Certain applications do not behave correctlyl with the RANDR extension. The "Use Scrollbars" option adds scrollbars to the single window allowing the viewport to be resized and shrunk as needed.
Some X-applications may request backing store on windows that are complicated to draw, which can slow down the response of the display. When a window is obscured, hidden behind another window, it must be redrawn when it is returned to the front. When cached, CPU usage is significantly decreased, and display time is accelerated.
How memory is stored, such as placed in memory that is reserved for graphical interface, can be configured.
When necessary to support legacy applications, PseudoColor can be selected.
