configuring X Windows on HP-UX (HP Visualize graphics cards) X Server configuration Figure 2-2 Two physical displays, two separate screens :0.0 /dev/crt0 :0.1 /dev/crt1 • This sample X*screens file could be used on a system using HP VISUALIZE-FXE with a 17-inch monitor. In this example, the GraphicsSharedMemorySize is decreased to 1 Mbyte in order to reduce the swap space requirements of the system. Decreasing GraphicsSharedMemorySize is appropriate when you do not intend to run any 3D graphics applications. ServerOptions GraphicsSharedMemorySize 0x100000 Screen /dev/crt MonitorSize 17 inches The display diagram would be the same as that of the "Results of Minimal Legal X*screens File" configuration, above. • This sample X*screens file could be used on a system with a HP VISUALIZE-FX5 graphics device. The overlay visual is selected as the default. There are 255 overlay colormap entries available on the HP VISUALIZE-FX5. The 256th entry is hard-wired to transparent. Having less than 256 colormap entries should not cause a problem for most applications, but for those applications that require 256 colormap entries, the CountTransparentInOverlayVisual screen option should be used as shown below. Note that any attempts to modify the 256th entry will have no effect on the colormap. Screen /dev/crt ScreenOptions CountTransparentInOverlayVisual The display diagram would be the same as that of the "Results of Minimal Legal X*screens File" configuration, above. • This sample X*screens file could be used on a system with a HP VISUALIZE-FX10 graphics device. The default visual on the HP VISUALIZE-FX10 is the opaque overlay visual. All 256 colormap entries are opaque and allocable. If an application requires transparency in the default visual, the "Transparent" keyword can be used to select the transparent overlay visual as shown below. 16 Chapter 2
