Why won't this TFT go to standby mode?!


I have an HP Pavilion F1903, when it is running, it normally has a blue backlight to the button. When it goes in to standby, it has an orange backlight - however, I've only seen it do that once and I can't remember how I did it - but I want it to do that!

As you can see, ACPI is compiled in, APM isn't.

in X with a CLI: xset dpms force [off, standby, suspend] all do the same thing: The backlight stays blue, the monitor stays outputting a black screen (as opposed to actually switching off) and then it says: Check Cable.

What am I doing wrong? All I want is to put the monitor in real standby. I always remember to turn off the monitor when I leave it, but my wife sometimes forgets, I'd rather not waste tons of electricity :)

Cheers for reading!

Steve

Ooooh, *embarrassed look*

Turns out I'm just an impatient idiot!

A friend popped around with his shiny new laptop, so I decided to use the video out on that and set up power saving under Win2k. Low and behold when we came back a couple of minutes later, it was in standby. I decided to sit down and watch it, about a minute after displaying, "Check Cable", it displays "Going to sleep" and goes into standby.

All I can suggest for those of you having problems is check that you have the following in xorg.conf:

Section "Monitor"
Option "DPMS"

Section "ServerLayout"
Option "OffTime" "1" # 1 minute of inactivity and your monitor will turn off

Oh well, I still feel silly!

Steve
