Hi,

I'm using X and an Intel graphics, so I only could try to interpret the
manpage.


$ man setterm | grep powerdown
       --powerdown [0-60]
              Sets the VESA powerdown interval in minutes.  Without an argument, it defaults to 0 (disable powerdown).  If the console is blanked or the monitor is in suspend mode, then
              the monitor will go into vsync suspend mode or powerdown mode respectively after this period of time has elapsed.
       --powersave powerdown
              Puts the monitor into VESA powerdown mode.

IIUC it's turned off by default. It's turned on by default, when using
X.


$ man xorg.conf | grep OffTime -A4
       Option "OffTime"  "time"
              sets the inactivity timeout for the off phase of DPMS mode.  time is in minutes, and the value can be changed at run-time with xset(1).  Default: 10 minutes.  This is only
              suitable for VESA DPMS compatible monitors, and may not be supported by all video drivers.  It is only enabled for screens that have the "DPMS" option set (see the MONITOR
              section below).

$ man xorg.conf | grep n\ \"DPMS -A2
       Option "DPMS" "bool"
              This option controls whether the server should enable the DPMS extension for power management for this screen.  The default is to enable the extension.

Regards,
Ralf
