xrefresh1

Usage

Overview

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. 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(7).

-display display

This argument allows you to specify the server and screen to refresh; see X(7).

-delay ms

Wait for ms milliseconds between mapping and unmapping the window. This can be useful for screens with slow response times, such as e-ink displays. The default is 0 ms.

-help

This argument prints the program options and exits.

-version

This argument prints the program version and exits.

X defaults

The xrefresh program uses the routine XGetDefault(3) to read defaults, so its resource names are all capitalized.

Environment

DISPLAY

To get default host and display number.
