Monitor Standby in Init3 Console


Hello,

I'm sorry if this question has been posted and answered elsewhere; search results for applicable terms either result in too many results or not enough.

Anyhow, here's the issue: To conserve memory, I operate my Linux (FC5) box in Init 3 (commandline console). When I am away from the console for a period of time, it blanks my monitor's screen but does not actually put it into Standby or Suspend. This, of course, is what I want to do. I'd prefer to have the monitor in a Power-saving mode than just a blank screen, for the sake of my electricity bill.

Can this be accomplished? If so, please tell me how.

<edit>
I'd like to add that Standby/Suspend works fine when running in Init 5, both KDE and Gnome. Similar posts all seem to refer to X rather than simple console.
</edit>

Regards,

diggerB

Try running this command:

Code:
xset dpms force off

Thanks very much for your response.

But when I enter that command, I get the following:

Code:
~]# xset dpms force off
xset:  unable to open display ""
This I imagine would be because I'm not running X. Any other ideas?

Regards,

diggerB

Same problem

I have the same problem, it seems that the video card doesn't tell the monitor to shut down, but in fact, it stops transmitting data to the screen.

Where else can the power management for console be configured?

You can use setterm to control the dpms in the console.

In my experience if you use DVI cables then the monitor never powers down properly.

Hi phil.d.g thanks for your response. I tried the setterm command as follows:

setterm -powersave 1 (to make it powerdown after 1 minute)

As this didn't work, i tried with (-powersave hsync , -powersave vsync , and -powersave on) modifiers.
None of them did anything. Could you tell what am I doing wrong?

PD: BTW, I have VGA, just in case you needed to know.
