Description:

KPowersave is the KDE frontend for powermanagement. It provides battery monitoring, suspend/ standby triggers and many more powermanagement features for KDE (and GNOME).

Current feature list:
- support ACPI, APM (and PMU since 0.7.x)
- trigger suspend to disk/ram and standby
- switch cpu frequency policy (between: performance, dynamic and powersave)
- applet icon/tooltip with info about AC state, and battery fill/(warning) states, remainig time
- scheme specific settings (see below)
- autosuspend (to suspend if a user was a defined time inactive)
- autodimm
- a global and scheme specific configurable blacklist with programmes to prevent autosuspend/autodimm (e.g. videoplayer and cd burning tools)
- trigger lock screen on lidclose ans suspend and select the lock methode
- define battery warning levels and related actions if a level reached
- actions for special button events (power/lid/suspend/sleep buttons)
- define AC/Battery default scheme
- KNotify support for many events
- online help and localisations

- KPowersave support schemes with following configurable specific settings for:
* screensaver/DPMS
* brightness (if supported by hardware)
* autosuspend/autodimm
* scheme specific blacklist for autosuspend/autodimm
* CPU Frequency Policy

- KPowersave contains a detailed dialog (on left mouse button on the applet icon) with all PM relavant info

To run KPowersave you need currently:
- dbus/dbus-qt3 (http://www.freedesktop.org/Software/dbus)
- HAL >= 0.5.9 (http://www.freedesktop.org/Software/hal)

Additionaly you can use the powersave daemon to handle powermanagement if no user is logged in to the system (http://sourceforge.net/projects/powersave/).

For (additional) dependencies see the project homepage and documentation.

If you run KPowersave on KDE you can remove klaptop from your system. KPowersave was developed as a replacement.

KPowersave and powersave are (as we know) running on this distributions:
* SUSE Linux (defaultly, available RPMs are for 10.0, for 10.1/10.2/10.3 see related repositories (www.opensuse.org), for 9.2/9.3 see older version on sf.net available)
* ALTLinux: default
* K/Ubuntu: from universe repository
* Debian: available via 'apt-get install kpowersave'
* Fedora Core 6/7/8 (sf.net)
* Mandriva 2007/2008(sf.net)
* Gentoo (ebuilds see download link)
* Arch Linux
* Slackware (http://www.mytux.org/content/viewslackpackage.php)
* (Simply)Mephis (since 6.0 default)
* FOX Linux (default)
* RR/RR64 Linux (default)
* PLD Linux (devel tree)
* Aurox (devel tree)
* Pardus
Packages and porting information for other distributions would be appreciated.

KPowersave 0.7.3:

Major changes since the last version/release:
- added new dialog to show logfiles if a suspend/resume fail and allow the user to save the log (need to get enabled per distro)
- added support to handle brightness key events if the machine not already handle this in the hardware directly
- added new feature named autodimm to reduce the brightness of the display if the user is inactive and dimm up if the user get active again
- new dialog shown up 30 seconds before
autosuspend call the suspend to warn the user and allow chancel the suspend
- added code to work with new PolicyKit/ConsoleKit/HAL combi to check if the user is privileged (for HAL >= 0.5.10 and related PolicyKit versions)
- added code to check if the current desktop session is avtive and handle if the session get inactive (via ConsoleKit)
- added code to release/aquire org.freedesktop.Policy.Power if the session get inactive/active to allow powersaved or other active KPowersave instances to handle powermanagement
- prepared KPowersave to work also with HAL >= 0.5.10 (handle renamed policy names in HAL)

Minor changes:

- fixed configure script to detect if we should use HAL to get information about policies instead of PolicyKit
- force update detailed dialog on AC events to get always e.g. the correct scheme info in the dialog

We found the reason for the not working autosuspend feature. The problem is the path for pidof in the code (/sbin/pidof). On Gentoo this is /bin/pidof. We fixed this for the next release, you can workaround this if you add a link to /sbin/pidof.

yes, the problem was with xsl libraries.
for people having the same problem:

hum... i've never created an ebuild before. i could do it if i wasn't completly stacked out of work... i'm on my final exams, finishing my final project on bioinformatics, and another project on advanced functional programming. if no one does it before the 21st february, i'll do it myself. otherwise... i won't :S

You couldn`t only compile the help. Looks as if you miss some xls or KDE doc packages.

please generate a .deb file to be able to use your so useful program (sincerely great) with ubuntu (debian).

Thanks a lot for this if you do it.

Have a nice day.

If you take a look in the description, there are already dep files for debian/ubuntu available (currently v0.5.2).

On Debian you can get KPowersave/powersave with 'apt-get install kpowersave' and for Ubuntu you can download packages from http://www.teco.edu/~biebl/ubuntu

I think the packages will be updated as soon as possible by the debian/ubuntu package maintianer/packager (Michael Biebl).

It works like a charm on my fc4 laptop.

I've compiled and installed both powersave and kpowersave, but when I start the latter, it only has two items in it's menu: "Help" and "Quit". What could that be?

Report

In this case I think powersaved or DBUS is not running - start/restart both daemons and it should work (maybe check also if HAL is running).

Report

I found out that powersaved quits just after being started. It creates /var/run/powersaved.pid, but there's no process with that PID.

I tried to debug, but GDB told "Program exited with code 01.", so it didn't crash.

Please set the variable DEBUB="" to DEBUG="15" in /etc/powersave/common, restart powersave and tell us what you see in /var/log/messages when powersave shuts down.

BTW: What is the powersave version and distribution you are working with?

Report

blaster999

13 years ago

Well, I realized I didn't have the /etc/powersave dir, so I created it and copied all the files from the source dir. Still, nothing worked. Although I've set the debug level to 15, not a single message appeared in the logs.

I'm using Gentoo, compiled powersave-0.11.5 by hand.

It would be usefull if you could write a mail to: 'powersave-devel at forge dot novell dot com' with a short description of your problem on Gentoo.

We could discuss this there in a better/easier way than here and would try to help you. Thanks.

No, there is everything you need to compile the package. Please take a look at the README, you will find there all needed information.

I try to install it with YaST and I get conflicts regarding libpowersave_dbus.so.10 not being available along with 2 other .so files.
Do I have to be running a special kernel or anything?

If you use SUSE 10.0 you also need to update your powersave with the new package from http://sourceforge.net/projects/powersave/ The powersave package was split off to powersave, powersave-libs and powersave-devel packages. So you need to install also the powersave-libs package.

Hi,
this is a great app especially since I'm right now struggling with KLaptop, which always shutsdown my laptop even though i'm not running that low on battery.

Do you plan to make it a replacement for the standard Kcontrol module for energy management? This would be really really great. Or don't you plan to make it Kcontrol module at all?

cheers
