NAME

screenblank − turn off the screen when the mouse and keyboard are idle

SYNOPSIS

screenblank [ −l ] [ −m ] [ −k ] [ −d interval ] [ −e interval ] [ −f frame-buffer ]

DESCRIPTION

screenblank turns off the display when the mouse and keyboard are idle for an extended period (the default is 10 minutes).  screenblank will continue to run until killed by hand, using ‘kill −9 processid’ or by logging out. 

OPTIONS

−l screenblank runs lockscreen -n so no password is required. 

−m Do not check whether the mouse has been idle. 

−k Do not check whether the keyboard has been idle. 

−d interval
Disable after interval seconds.  interval is a number of the form xxx.xxx where each x is a decimal digit.   The default is 600 seconds (10 minutes). 

−e interval
Enable within interval seconds.  interval is the time between successive polls for keyboard or mouse activity.  If a poll detects keyboard or mouse activity, the display is resumed.  interval is a number of seconds, of the form xxx.xxx where each x is a  decimal digit.  The default is 0.25 seconds. 

−f frame-buffer
frame-buffer is the path name of the frame-buffer on which video disabling/enabling applies.  The defaults is /dev/fb. 

On the Sun386i only, getty(8) commands in /etc/ttytab (see ttytab(5)) invoke logintool(8), which starts screenblank on you behalf.  screenblank runs with the −l option, and the −e option (for 30 minutes).  Logging out does not terminate the screenblank process because it was started by logintool.
