## Name

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(7) .

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

## X Defaults

The xrefresh program uses the routine XGetDefault(3X) 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

DISPLAY - To get default host and display number.

X(7)

## Bugs

It should have just one default type for the background.
