Problem description:
My RPi is connected to a Samsung LCD SyncMaster 2243N VGA monitor through an HDMI-VGA adaptor.
When the black screensaver starts, the monitor doesn't go to standby and stays on, illuminating the room by showing a black image.
Is there a way to make the monitor switch to standby when idle?

Thanks in advance for any help,
Alex

Have you tried in xbian-config "Turn CEC capable TV OFF with screensaver"?

Never tried it but it might suit your needs.

Or try System -> Input -> CEC adapter "Put devices in standby mode"

If your screen is not CEC enabled, I think you are out of luck.

[mrpi]

Yes, but sadly, it doesn't work. What could influence this? Could you point me in the right direction?

[IriDium]

Missed this point - you're going through a HDMI -> VGA adaptor. If I'm right, VGA has no CEC capabilities, so I'm afraid there is nothing that can be done in software.

[mrpi]

When I shutdown, the monitor normally switches to standby like at the first command.
Isn't there a way to simulate this lack of signal?

[IriDium]

That's the monitor detecting no signal from the hardware. As far as I know there is no way of doing that in XBian. Sorry

BTW: In future, if you add your RPi configuration into your user profile you can just point a post to it, instead of entering it each time you post a new thread.

I found that I can turn it off with:

Quote:/opt/vc/bin/tvservice -o

But if I try:

Quote:/opt/vc/bin/tvservice -p

It will turn on without image.

Try:

Code:

vcgencmd display_power 0
vcgencmd display_power 1

Thank you menakite!
It's working perfectly!
Now I can finally automate this
