KDE: Display Power Control is missing

Hi,

Google says that in System Settings->Display there should be a Power Control tab. I've got none; probably, a package is missing. What is it?

It looks like that must be an older version of KDE 4. In my KDE 4.4.3 it has moved. Now in System Settings click the Advanced tab and then choose Power Management.

Re: KDE: Display Power Control is missing

Thanks! I've got a normal mains powered box; I want to prevent my display from turning off, that's all. Judging by the looks of System Settings->Power Management it's dimly aware that the box isn't a notebook, which is good. Unfortunately, unchecking Enable display power management in profiles doesn't make any difference. Any suggestions?

That I cannot help you with. You said you didn't have a notebook; I do and I use the power management to turn off my screen after 30 minutes of inactivity. Before I enabled that it would always stay on. I'm not sure why yours WOULD turn off if you didn't have it set to do that.

If you have a desktop and an external monitor maybe it has something to do with the monitor (don't monitors turn themselves off after some time of inactivity? I don't really know).

Now that you mention it: I do have a notebook. Arch+KDE, too. The screen would turn off after a timeout, just as it should. I've never touched a thing in Power Management there

Re: KDE: Display Power Control is missing

Did you install pm-utils? ( http://wiki.archlinux.org/index.php/Pm-utils )

I believe I had to install that to get any of the powersaving features to work in KDE. If you didn't, or if they are installed but turned off in Power Management then I can't imagine what it would be. My suggestion would be just to go into Power Management and just look around and turn all that off, even though you haven't changed anything in there to begin with.

Yes. Looks like they've always been there
