XREFRESH(1) MachTen Programmer’s Manual XREFRESH(1)

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 win-
dow 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 back-
ground 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

-geometry WxH+X+Y
Specifies the portion of the screen to be
repainted; see X(1).

-display display
This argument allows you to specify the
server and screen to refresh; see X(1).

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

Black, White, Solid, None, Root

It should have just one default type for the background.
