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 framebuffer due
	     to inactivity.  The default is 600 seconds (10 minutes).

     -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.
