SCREENBLANK(1)		  BSD General Commands Manual		SCREENBLANK(1)

NAME
     screenblank — screen saver daemon for wscons and FBIO machines

SYNOPSIS
     screenblank [-k | -m] [-d inactivity-timeout] [-e wakeup-delay]
		 [-f framebuffer] [-i input-device]
     screenblank {-b | -u}

DESCRIPTION
     screenblank disables the framebuffer if the keyboard and mouse are idle
     for a period of time, and re-enables the framebuffer when keyboard or
     mouse activity resumes.

     When killed with a SIGINT, SIGHUP, or SIGTERM, screenblank will re-enable
     the framebuffer.  The pid can be found in the file
     /var/run/screenblank.pid.

     The options are as follows:

     -b	     Overriding the other options, simply try (once) to blank the
	     framebuffer, then exit.

     -d inactivity-timeout
	     Wait the number of seconds specified by inactivity-timeout,
	     expressed in the format “xxx.xxx”, before disabling the frame‐
	     buffer due to inactivity.	The default is 600 seconds (10 min‐
	     utes).

     -e wakeup-delay
	     Wait the number of seconds specified by wakeup-delay, expressed
	     in the format “xxx.xxx”, before re-enabling the framebuffer once
	     activity resumes.	The default is .25 seconds.

     -f framebuffer
	     Use the framebuffer device framebuffer instead of the default
	     /dev/fb.

     -i input-device
	     Add input-device to the list of devices to monitor for activity.

     -k	     Do not check the keyboard for activity.

     -m	     Do not check the mouse for activity.

     -u	     Overriding the other options, simply try (once) to unblank the
	     framebuffer, then exit.

     Note that the -k and -m flags are mutually exclusive.
