| xdg-screensaver - command line tool for controlling the screensaver |
| |
| Synopsis |
| |
| xdg-screensaver suspend WindowID |
| |
| xdg-screensaver resume WindowID |
| |
| xdg-screensaver { activate | lock | reset | status } |
| |
| xdg-screensaver { --help | --manual | --version } |
| |
| Description |
| |
| xdg-screensaver provides commands to control the screensaver. |
| |
| xdg-screensaver is for use inside a desktop session only. It is not recommended |
| to use xdg-screensaver as root. |
| |
| Commands |
| |
| suspend WindowID |
| |
| Suspends the screensaver and monitor power management. WindowID must be the |
| X Window ID of an existing window of the calling application. The window |
| must remain in existance for the duration of the suspension. |
| |
| WindowID can be represented as either a decimal number or as a hexadecimal |
| number consisting of the prefix 0x followed by one or more hexadecimal |
| digits. |
| |
| The screensaver can be suspended in relation to multiple windows at the |
| same time. In that case screensaver operation is only restored once the |
| screensaver has been resumed in relation to each of the windows |
| |
| resume WindowID |
| Resume the screensaver and monitor power management after being suspended. |
| WindowID must be the same X Window ID that was passed to a previous call of |
| xdg-screensaver suspend |
| activate |
| Turns the screensaver on immediately. This may result in the screen getting |
| locked, depending on existing system policies. |
| lock |
| Lock the screen immediately. |
| reset |
| Turns the screensaver off immediately. If the screen was locked the user |
| may be asked to authenticate first. |
| status |
| Prints enabled to stdout if the screensaver is enabled to turn on after a |
| period of inactivity and prints disabled if the screensaver is not enabled. |
| |
| Options |
| |
| --help |
| Show command synopsis. |
| --manual |
| Show this manualpage. |
| --version |
| Show the xdg-utils version information. |
| |
| Exit Codes |
| |
| An exit code of 0 indicates success while a non-zero exit code indicates |
| failure. The following failure codes can be returned: |
| |
| 1 |
| Error in command line syntax. |
| 3 |
| A required tool could not be found. |
| 4 |
| The action failed. |
| |
| Examples |
| |
| xdg-screensaver suspend 0x1c00007 |
| |
| Causes the screensaver to be disabled till xdg-screensaver resume 0x1c00007 is |
| called. 0x1c00007 must be the X Window ID of an existing window. |
