How to: Update Kpowersave -> better Battery Management

Hi hiker_jon!

1. with "garbage" you mean the screen displays odd things? (haven't noticed anything with my AAO)
2. Indeed its fast and its not the same as when shutdown through panel. But its the common way to shutdown linux!
Is it safe? Again, haven't noticed anything wrong with this method. For me its safe, although I prefer the panel method ;-)
3. /home/user/.kde/share/config/kpowersaverc

With KPowersave update, Power Center shortcut will stop working. To fix it, you must change /usr/share/applications/powercenter.desktop :

Code:

$ sudo mousepad /usr/share/applications/powercenter.desktop
...
#Exec=kpowersave --show-config
Exec=dcop kpowersave KPowersaveIface openConfigureDialog
...

 

I had the power button set for shutdown. That doesn't work and neither does the logout dialog option. So I figured that nothing worked, but I see that the suspend to ram option does work. That is good enough for me.

Sorry for snipping like that. I had (incorrectly) assumed that the OP's previous reply to the same problem had resolved it. I now realize that I had the same problem as you, and am glad you brought it up again, getting a resolution for both of us.

I used the OP's fix, which works fine, and the power center shortcut fix, which doesn't. It's not necessary, as the tray icon is more convenient, but does the edit work for anyone else?

 

I recently did the kpowersave update and when i rebooted my touchpad stopped working!
any ideeas what the problem might be its really irritating. i myself has no clue what it might be. i need to fix this ASAP!


Update: i just uninstalled kpowersave and now my touchpad works :S.
i want the kpowersave, does anyone know a solution?

thanks for your time.

To get the power button to make the computer sleep again after updating Kpowersave do the following:

Make the action line of /etc/acpi/events/power.conf read:

Code:

action=/etc/acpi/actions/sleep.sh %e

Then from the commandline do:

Code:

sudo kill -SIGHUP `pidof acpid`

to restart acpid and reload the config.

Your power button will now act as a sleep button.

have anyone tried rob's solution?

 

Hi Blackhawk,

I've tried editing my powercenter.desktop file as you suggest, but the Power Center shortcut still doesn't work.
However, when I enter the command 'dcop kpowersave KPowersaveIface openConfigureDialog' in a terminal window, the kpowersave configuration menu comes up no problem.

Any ideas?...sorry, I'm still a Linux noob!

Ken...

 

Have you rebooted? It definitely does work.

Rob

 

Does the new Power Center update overwrite this newer version of Kpowersave? If so, which works better on the AA1?

 

Hi Rob,

Yes I have rebooted and the shortcut still doesn't work...I am talking about the shortcut in the xfce menu though as I've done tha chnages to have the 'normal' xfce menu instead of the Acer one...maybe that's the difference?

Ken...

 

I tried this just this morning and everything was working fine, the shutdown on the panel, the power button, suspend etc.

I thought I have to edit the file so that the power button would work but when I get there, the file I am supposed to add is already there on the last part of the line so I did not touch it at all. I felt skeptic and tries the power button and it was working.

So basically, I just downloaded it via the yumdownloader and forced install the rpm and everything works fine out of the box, with no problems and minus the tweaking, aside from setting up my preferences. I wonder if what I got is some sort of a new version? By the way, thanks a lot Tybor, this is extremely useful.

 

I followed the instructions in this thread too to install the full blown kpowersave.
It installed and runs fine, however, I noticed that it cant play any sounds.
Sound on my AAO is basically OK (plays well on VLC and youtube) but kpowersave cant play .ogg or .wav files.
Any ideas what it could be? Do I need to install a separate package?

 

mine either, I have been wondering why you cannot use "system sounds"

 

hello,
before restoring a backup, I tried updating different stuff,
and then I directly update Kpowersave with yumex (without taking into account that post, I did not even read it)
and I was very surprised : everything just worked very well, directly out-of-the-box.
I didn't need to tweak anythings.
of course I didn't performed deep test,
and I finally broke everything by updating fuse and hal (and kernel)...

but when I read now your post, I'm septical...
do we still need to perform all these action you mention ? maybe it's outdated with new package ?

does anybody else did perform such update before reading that post ?

The problem is I've now customized a lot and I don't want to perform tests again.

 

Hi hpfx,

Your "all these actions" are 3 simple commands. First one is to update your repository config, Second downloads the newest kpowersave package and last one installs this package via rpm. Basically yumex does the same but will probably complain about dependencies.

So to answer your questions: Yes; No; Perhaps

I read in this thread that some people get ~3 hrs after updating Kpowersave and changing some settings...What settings are you guys using. I can only get it to about 2 hours 15 mins max.

thanks

 

Same question here, I dont get those 3 hrs.
I keep getting something around 2.5 hrs with and without kopwersave described here.

 

Hi Tybor,

Thanks for your hard work and sharing.
I've got a few questions, sorry to bother you but i don't want to wreck my new gadget.

in your first post you're talking about the new fedora-release 8-6 package
Are you referring to, already installed on my system:
fedora-release - 8-6 transition.noarch? (Question.1)

when i check package manager for yum-utils i find 2 "Available' packages:
yum-utils - 1.1.8.1.fc8.noarch
yum-utils - 1.1.17-1.fc8.noarch
Which one do i need, if any of these (Question.2)

Another check in package manager gives me as "Installed "
kpowersave - 0.7.3-2.9.noS4.lp.i386
i can find no "Available" kpowersave packages (Question.3)

In one of your last post on 27 Dec 2008 17:42 you say

Somewhere i'm getting lost in your explanation.
As far as i am aware i haven't updated my repositories. and to be honest i don't understand where that updating takes place... i guess, based on the quote above, by issuing the command:
sudo yum install fedora-release yum-utils, (Am i right?) (Question.4)

I have Linpus Linux Lite v1.015.E, would that account for my confusion?(Question.5)

Sorry for all the reading material..and questions

Regards,
woodland

 

Thanks works perfectly!

 

To get about 3hrs you have to set the CPU Frequency Setting to "Energy saving" (sry don't know exact english names, I'm using german), so the CPU stays at 800MHz in Battery mode. Next the time is measured without active WLAN! This is important becasue WLAN consumes a lot of power.

So to woodlands questions:
Q1: Looks like it, so yes.
Q2: One is installed on your system, the other one is the actual package, you need most recent one (1.1.17)
Q3: see quick guide
Q4: yes
Q5: might be, dunno this version.

quick guide:
You don't need to have any concerns about messing up your gadget. This HowTo is used by several ppl all having no problems.
To clarify instructions, you only have to open a terminal (press Alt+F2; type terminal; Run) and execute the 3 commands one after the other.

• The 1. updates your repository and installs yumdownloader.[/*:3w3rgm1t]
• The 2. downloads most recent kpowersave package.[/*:3w3rgm1t]
• The 3. installs the previously downloaded kpowersave package.[/*:3w3rgm1t]
