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.
