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.
-

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.
-

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).
