DESCRIPTION
       xdg-screensaver provides commands to control the screensaver.

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 existence 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
