screenblank
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 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.
FILES
/dev/kbd The keyboard device.
/dev/mouse The mouse device.
/dev/console The console device.
/dev/fb The default framebuffer.
/dev/wskbd The keyboard for wscons machines.
/dev/wsmouse The mouse device for wscons machines.
