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 X(7x)
.
- -display display
- This argument
allows you to specify the server and screen to refresh; see X(7x)
.
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.
- DISPLAY - To get default
host and display number.
X(7x)
It should have just one default
type for the background.
