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 immedi-
     ately 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  back-
     ground 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 X11(7).

     -display display
               This   argument   allows   you   to   specify  the
               server and screen to refresh; see X11(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.

SEE ALSO
     X11(7)

BUGS
     It should have just one default type for the background.
