xrefresh - refresh all or part of an X screen


   xrefresh [-option ...]


   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.


   -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

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


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

   Black, White, Solid, None, Root
           Determines what sort of window background to use.

           Determines the area to refresh.  Not very useful.


   DISPLAY - To get default host and display number.




   It should have just one default type for the background.
