SCREENBLANK(1)              NetBSD Reference Manual             SCREENBLANK(1)


NAME

     screenblank - screen saver daemon for wscons and FBIO machines


SYNOPSIS

     screenblank [-k | -m] [-d timeout] [-e timeout] [-f framebuffer]


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:

     -k      Do not check the keyboard for activity.

     -m      Do not check the mouse for activity.

     -d timeout
             Wait the number of seconds specified by timeout, expressed in the
             format `xxx.xxx', before disabling the framebuffer due to inac-
             tivity.  The default is 600 seconds (10 minutes).

     -e timeout
             Wait the number of seconds specified by timeout, expressed in the
             format `xxx.xxx', before re-enabling the framebuffer once activi-
             ty resumes.  The default is .25 seconds.

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

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