<P><CODE>setterm -blank</CODE> <I>nn</I> will tell the console driver to blank the
screen after <I>nn</I> minutes of inactivity. (With <I>nn</I> = 0, screensaving
is turned off. In some old kernels this first took effect after the next
keyboard interrupt.)
<P>The <CODE>s</CODE> option of xset(1) will set the X screensaving parameters:
<CODE>xset s off</CODE> turns off the screensaver,
<CODE>xset s 10</CODE> blanks the screen after 10 minutes.
<P>The video hardware powersaving modes can be enabled/disabled
using the <CODE>setvesablank</CODE> program given in the starting comment of
<CODE>/usr/src/linux/drivers/char/vesa_blank.c</CODE>.
