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(7). |
−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. |
Geometry |
Determines the area to refresh. Not very useful. |
DISPLAY - To get default host and display number. |
X(7) |
It should have just one default type for the background. |
