X Version 11 (Release 6.1)

xrefresh(X1)

xrefresh -- refresh all or part of an X screen

Synopsis

xrefresh [-option ...]

Description

xrefresh is a simple X program that causes all or part of your screen to be repainted. This is useful when system messages have messed up your screen. xrefresh maps a window on top of the desired area of the screen and then immediately unmaps it, causing refresh events to be sent to all applications. By default, a window with no background is used, causing all applications to repaint ``smoothly.'' However, the various options can be used to indicate that a solid background (of any color) or the root window background should be used instead.

Arguments

-white: Use a white background. The screen just appears to flash quickly, and then repaint.
-black: Use a black background (in effect, turning off all of the electron guns to the tube). This can be somewhat disorienting as everything goes black for a moment.
-solid color: Use a solid background of the specified color. Try green.
-root: Use the root window background.
-none: This is the default. All of the windows simply repaint.
-geometry WxH+X+Y: Specifies the portion of the screen to be repainted; see X(X1M).
-display display: This argument allows you to specify the server and screen to refresh; see X(X1M).

X defaults

The xrefresh program uses the routine XGetDefault to read defaults, so its resource names are all capitalized.

Black, White, Solid, None, Root: Determines what sort of window background to use.
Geometry: Determines the area to refresh. Not very useful.

Environment variables

DISPLAY: To get default host and display number.

Warnings

It should have just one default type for the background.
