PowerDevil

   1.4.2  

KDE System Tool

Score 90%
Minimum required   KDE 4.x
Downloads:  5218
Submitted:  Jul 12 2008
Updated:  Feb 1 2009

Description:

--- ATTENTION ---

This page will be no longer updated, just like 4.1 backports, now that 4.2 is out. PowerDevil is now in kdebase module, so from 4.2 on there is no need to download/install it as a separate application. Please use bugs.kde.org for bug reports/feature requests/whatsoever. Thanks for testing and trying PowerDevil in 4.1, we have a rock solid powermanager in 4.2 mostly thanks to you!

PowerDevil is an utility for KDE4 for Laptop Powermanagement. It consists of a Daemon (a KDED module), a KCModule to configure it, and will feature a Plasmoid soon.

With PowerDevil you can set up preferences for lid Closing, Brightness, CPU scaling, Idle time, both when connected to AC and when on Battery. It is built upon Solid, and it's very lightweight and won't overkill your system resources. If you missed KLaptop or KPowersave, this might be the tool you were looking for.

PowerDevil is part of kdebase from 4.2 on. This means it's included in kde core releases and you no longer need to compile it as an external application.

Though, I keep a branch and a tarball updated for people on KDE4.1. Enjoy it!

-- Changelog for the 4.1 branch --

How does one go about compiling and installing this app?

Rather simple: it just builds like any other KDE app (cmake . -DCMAKE_INSTALL_PREFIX=/usr && make && make install).
Once done that, relogin. In systemsettings you'll find a new module, configure powerdevil from it, and you're done.

Thats what I thought, but...

I extracted the tarball, cd'd to the directory, created a build directory and cd'd to it.

Then

cmake . -DCMAKE_INSTALL_PREFIX=/usr && make && make install

and I get the following:

-- The CXX compiler identification is unknown
-- Check for working CXX compiler: CMAKE_CXX_COMPILER-NOTFOUND
CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found. Please set CMAKE_CXX_COMPILER to a valid compiler path or name.

No difference if I run sudo.

Looks like you're missing a compiler. Try installing g++ and gcc and retry, ask on your distro forums what packages you need to set up a building environment

make still failed. the missing file from krunner is located at:

instead of /usr/share/

 Does it work?

 
 by dbglt1 on: Sep 8 2008
 
Score 50%

Tried from both svn and the tarball. Built and installed succesfully.

My problem is that the plasmoid just displays a little black box (no image).

Also, I can change the settings in systemsettings module, but it doesn't actually seem to have any effect (ie. brightness not dimmed, cpu not slowed, etc.)

Not sure what's going on!

It does work, the plasmoid is still being worked on. Check if PowerDevil service is running under "Services" in systemsettings. Then be assured to configure correctly your profiles, refer to the manual if you're in doubt (svn version)

Yeah, that interface is installed by KRunner, so you eventually miss one, check in your distro forums what's missing.

well, it seems the file org.freedesktop.ScreenSaver.xml is located in /usr/lib/kde4/share/dbus-1/interfaces/ instead of /usr/share/dbu..., copying it to the latter directory solved the problem and it compiles now. I am running Kubuntu 8.04, and I guess this might be a distro thing.

Found the reason - if you compiled and installed the stuff with that
cmake -DCMAKE_INSTALL_PREFIX=/usr
in Kubuntu 8.04 then it won't work - the thing is KDE4 is installed into /usr/lib/kde4 thus everything kde related should be installed there. So, just instead of ...PREFIX=/usr it should be ...PREFIX=/usr/lib/kde4
The system settings control module will appear under advanced tab. But i haven't found any plasmoid for it. i'll search better for it, though...

Looks like you're missing XScreensaver library. Please install it (along with the -dev package, if your distro has it), and retry.

That's what I think. But I've not been able to determine the actual package.

Here's what is installed.

ii xscreensaver 5.05-3 Automatic screensaver forX
ii xscreensaver-data 5.05-3 data files to be shared among screensaver frontend.

Do you guys have an idea what -dev package it is (Debian)?

I found this guide http://www.heutediewelt.nl/2008/09/switch-to-kde-4-and-compiling-powerdevil/ , obviously the svn address is now outdated, but it should be what you're looking for :)

So I successfully installed and ran it.

Here's some observation:
My current power manager is powersaved. * When using PowerDevil, I see only 1 profile, Performance.
* The CPU temp rises to 86 degree celsius. With powersaved, it was 55.
* Some kded crashes occured.

Well, there are still no defaults, you have to create your profiles and assign them. The default profile puts the system in performance mode, so it's quite expected your CPU temperature rises :)
About the crashes, can you please provide backtraces?

I've updated the guide drf mentioned earlier with the new SVN URL (http://www.heutediewelt.nl/2008/09/switch-to-kde-4-and-compiling-powerdevil).

The current SVN source is giving me problems though, cmake reports an error about a missing function (kde4_add_kcfg_files). The tarball works perfectly for me though.

To everyone: you need development files for libxss, the equivalent of libxss-dev in Debian.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
