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. |
|
