Damn Small Linux & Power Management

ACA:Sleeper · 10th September 2009, 11:57 AM

I setup an old laptop with the latest DSL to simply show a webpage on an external monitor. This works great, BUT, I can't work out how to change the power management to just leave it running 24/7.

Any ideas?

What's the issue you've got with the current power management? What does it do that makes it a problem?

DSL is based on debian iirc,

Code:

dpkg -l | grep power
#or
dpkg -l | grep pm

will narrow down the list of packages that provide some sort of power management capabilities -

Code:

dpkg -L <package>

will tell you what files that package installed - have a look for the files under */bin/* and /etc/ and between man and */bin/<prog> -h you should be able to narrow down how to manipulate it.

Thanks for the reply Cleary.

The screen shuts down after 15min or so, I assume if this is fixed, other issues like time till susspend or hibinate will be an issue too.

Overview....
Where I work, they just built some 'green' buildings, these have everything controlled with a building management system. It operates the heating and cooling, water tanks etc etc...
They put an LCD in the foyer, and it is ment to display the building statuses via a scrolling webpage. So I just need it to be on 24/7 showing a single website. I need to turn all power management off and just let it run.
