• This is the minimum specification for a two-screen configuration. The maximum number of
screens supported on the X server is four. Here, the displays associated with /dev/crt0 and
/dev/crt1 are referred to as "<host>:0.0" and "<host>:0.1", respectively.
Screen /dev/crt0
Screen /dev/crt1
• This sample X*screens file could be used on a system using Internal Color Graphics 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.

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 CRX24 graphics device. The
overlay visual is selected as the default. There are 255 overlay colormap entries available on the
CRX24. 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. Any attempts to modify the 256th entry will have no effect on the colormap.

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 HCRX-24 graphics device. The
default visual on the HCRX-24 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.
