SCREENBLANK(1) BSD General Commands Manual SCREENBLANK(1)NAMEscreenblank — screen saver daemon for wscons and FBIO machines
SYNOPSISscreenblank [-k | -m] [-d inactivity-timeout] [-e wakeup-delay]
[-f framebuffer] [-i input-device]
screenblank {-b | -u}
DESCRIPTIONscreenblank 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.
