* XScreenSaver 4.18: screen blanked since Tue Sep 14 14:10:45 2004
*
* Or you can monitor the _SCREENSAVER_STATUS property on root window #0.
* Element 0 is the status (0, BLANK, LOCK), element 1 is the time_t since
* the last state change, and subsequent elements are which hack is running
* on the various screens:
* % xprop -f _SCREENSAVER_STATUS 32ac -root _SCREENSAVER_STATUS
* _SCREENSAVER_STATUS(INTEGER) = BLANK, 1095196626, 10, 237
*
