NAME

Xnest - Recursive X window system implementation

DESCRIPTION

This implementation allows you to run an X server in a window of another X server.  Full functionality is supported.  The number of planes provided by this pseudo-device is the same as the underlying device.  The cursor sizes, tile sizes, and brush sizes supported are also the same.  The number of color cells provided is specified with a .Xdefaults option. 

Aside from being a good hack, this implementation exists primarily to aid system developers when debugging the device-independent portion of the server.  The debugging can be accomplished without requiring a second physical display. 

Exposures on (and resizings of) the window are ignored, and so corrupt the "screen". 

X DEFAULTS

Accepts the following defaults (for the program "X", not "Xnest"):

BorderWidth
Set the border width of the window.

Border Set the border color. 

CellExponent
If not set or set to zero, a monochrome psuedo-display is created. Otherwise, if a value of N is provided, specifies the maximum number color cells to be 2^N.  The number actually provided will be a power of two, but may be less than 2^N if allocation fails.

ENVIRONMENT

Uses the environment variable “DISPLAY” to specify which display to use.
