[SOLVED] Power Management in KDE doesn't work

Hello world :-)
I just installed Arch and everything works well except for Power Management in KDE. The Power Management settings in System Settings are completely grayed out and provided with following message:
"Power Management configuration module could not be loaded. The Power Management Service appears not to be running. This can be solved by starting or scheduling it inside Startup and Shutdown."
However the Power Management service is already running and if I restart it I get the message:
"KDE Power Management System could not be initialized. The backend reported the following error: No valid Power Management backend plugins are available. A new installation might solve this problem. Please check your system configuration."
I have this problem since KDE installation, Power Management just never worked. After two days of googling I becoming a little bit desperate :-) Any idea what's wrong here?

Not sure about that. I installed upower but I don't know how to configure it or if any configuration is needed. If I understand official documentation correctly, upower daemon should be started automatically if some application needs it.

I have full KDE installation (# pacman -S kde-meta) so problem should be in my Arch installation, no in KDE itself. I have only installed Arch, Xorg, proprietary Nvidia drivers and KDE so far, so there is only small chance I break or messed up something - it's more likely something I didn't install yet or didn't know how to configure.

[Solved] power management during kde startup not loading

Hi,
after solving one problem here comes another. From on side it's onying, but on the other side I lesrn a lot about my system.
Well this time after the last kde update, I get the following message:
KDE Power Management System could not be initialized. The backend reported the following error:
No valid Power Management backend plugins are available. A new installation might solve this problem.
Please check your system configuration.
So I went to:System Settings>>Power Management and the pane on the right is greyed out and there is a message:
Power Management configuration module could not be loaded. The Power Management Service appears not to be running.
This can be solved by starting or scheduling it inside "Startup and Shutdown"
System Settings>>Startup and Shutdown>>Service Manager, shows that Power management is running.
If I try to start upower manually I get the following message:
/usr/lib/upower/upowerd
(upowerd:30849): UPower-WARNING **: Failed to acquire org.freedesktop.UPower: Connection ":1.77"
is not allowed to own the service "org.freedesktop.UPower" due to security policies in the configuration file
(upowerd:30849): UPower-WARNING **: Could not acquire name; bailing out
I found this post: http://forums.opensuse.org/showthread.p … KDE-4-11-1
where it states tha this was a bug in some previous kde releases.
Well apparently it happened again here.
I read somewhere that it could be because the policykit rules weren't update. I tried to understand policykit conf files but for no avail. I'm twice lefthanded on that matter.
Any takers?
PS.: Checking with journalctl -r I found that upowerd was masked, so I did;
#systemctl unmask upower.service
than I enabled it;
#systemctl enable upower.service
and if you want to start it right away than;
#systemctl start upower.service
Well that's it.

Hi Tim,
To answer your question, I use the Lenovo pages in the US because support takes you right back to the US pages even if you begin at the lenovo.com.mx page. All driver and downloads revert to the www.307-ibm pages.
As for the link, unless they are filtering on my Latin American IP address, it should work as well as any other link anywhere in the world. It's just an http: URL. isn't it?
Here's the link that the item points to:
http://www.pc.ibm.com/cgi-bin/tpsolutions.cgi?version=20&link=battery_replacement&mtm=6459CTO&countr...
Is it the same as your? I suspect the error is in the syntax of the link which is pointing to my model and the correct battery FRU.

[solved] power management without HAL and pm-utils

hi guys! i got rid of hal and pm-utils, but i'm having some troubles now with the powersaving settings.
i'm using hibernate-script with uswsusp tools to hibernate etc, and laptop-mode-tools with acpi for the power management, but this looks like it isnt working anymore.
for example the screen backlight wont shut down anymore when i close the lid, despite the acpi action scripts are all ok.
far more importantly the cpu fan doen't ever start!! earlier this morning the cpu hit 77°C (while it's normally 40°) but the fan didn't kick in!
what can i do?
EDIT:
wait, maybe it's just the new kernel i've installed this morning! it's some days now that i've uninstalled hal and i think i would have noticed before!
Last edited by v43 (2011-02-23 11:25:10)

disabling laptop-mode-tools temporarily solved the problem. i mean the fan is now spinning free ^^
i'll try reinstalling it or downgrading the kernel later

Windows 7 RTM x64 Power Manager and switchable graphics not working

Installed Windows 7 RTM x64 on my T400. After windows update and installing Lenovo's drivers, everything is accounted for. ATI graphics works fine, and I can see the Intel graphics on the shortcut menu. I just cannot manually switch to the built-in graphics, nor did I see the Power Manager. What do I need to do? I have installed the drivers for the power management, even though on the list of driver on lenovo's webpage it says it's only for SL models.
Help would be appreciated.
Specs:

Have you installed the Power manager http://www-307.ibm.com/pc/support/site.wss/WIN7-BETA.html#powm ?
And after that, make sure you have installed the right driver (the one for switchable graphics): http://www-307.ibm.com/pc/support/site.wss/WIN7-BETA.html#m8xswitch
Hope that helps.

Hello, stashmore94.
Thank you for visiting Apple Support Communities.
Usually the reason for interrupted, stalled or canceled syncing alerts is a result of either security software interference or TCP/IP modifications. Also, non Apple cables and low powered USB hubs can cause this issue. Here are a couple resources that I would recommend going through as they may help resolve the issue.

How to disable safe mode on xperia z1,power and volume button doesn't work

Hi rafharum,
Welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
A simple restart to the device would generally resolve this issue, however if the power key and Volume key are not working they may very well be causing the handset to execute safemode when ever you power the device on.
If this is the case, you will need to get the handset to a service agent for assessment. Please use the link below to contact Sony Mobile Customer Care directly.

[SOLVED]Something wrong with Locale, "ÅÖÄ" doesn't work in terminal.

If you have this kind of problem stated above in the title, or similar, here is what I did...
Make sure you have correct locale, you'll need a UTF-8 one.
As stated in the install guide(or beginner's guide iirc) do the following:
Uncomment one of the locales in "/etc/locale.gen", it doesn't have to be language pacific if you're only after using UTF-8 which provides more characters than normal ASCII.
then run "locale-gen". Make sure to set your "/etc/locale.conf" to "LANG=en_US-UTF8" of course you can choose whatever locale you want not just "en_US-UTF-8". After that make sure to reboot, it may also work with just log-out and log-in again, but I did not reboot and neither log-out and when back in. If it still doesn't work, run "locale" and "locale-a" if the output is "C" in each column just redo what I stated above, if it still not work, then you have to consult the manual, wiki and if you don't find the problem use a search-engine and if you still don't find answer here on the forums, the people here is really helpful!

" Okey I uncommented sv_SE.utf8 in /etc/locale.gen ...
You're supposed to uncomment "sv_SV.UTF-8 UTF-8", then run locale-gen (with sudo), not "sv_SE.utf8".
That's what I did.
https://wiki.archlinux.org/index.php/Be … ide#Locale
^ Except that you shouldn't use "echo" in this case. That command works well when you're logged in as root, but for sudo, not so much. Check the file with nano and you'll see that nothing changed. For sudo, use tee.
$ sudo tee /etc/locale.conf <<< "LANG=en_US.UTF-8"
Note: You don't necessarily need "sv_SV" for those characters to show up. Setting a "sv_SV" locale would make programs show up in Swedish instead of English - unless that's what you want. UTF-8 locales will cover those characters just fine (provided that the font from the terminal actually contains those glyphs, of course).
So you mean I can have en_US.UTF8 as locale but still write swedish letters? So the problem is with the font or somthing, not the locale?
If you still have problems, post the output of:
$ ls -l /etc/profile.d/locale.sh
$ curl sprunge.us -F sprunge=@/etc/locale.gen
$ curl sprunge.us -F sprunge=@/etc/locale.conf
$ locale -a
$ locale
Well, I did as the guide told about locale.conf, it doesn't seem to work, even if "locale" outputs correct info now, but I'll try with restarting the X server too, just in case.....

[SOLVED] vfs_zip plugin for deadbeef doesn't work

hello everybody here,
i found vfs_zip plugin here doesn't work,
that is, i can import music files from zip archive, but i can't play them-
if i play those ones, the deadbeef'll be stuck ,even if i try play other files.
so, any solution here? any idea is appreciated, and thanks in advance:-)
BTW:
i have installed libzip in advance, so i think it's not the cause...
and i've tried deadbeef (from repo) and deadbeef-git (from aur), but still useless, eh

It's working fine for me, I just zipped up 1GB (262 files) of MP3's to test it out for you, and it's working just fine for me after it imports them into DeaDBeeF.
Open up a terminal, and type deadbeef and when you try and play the MP3's from the zipfile does it show any type of error message in the terminal? If so, paste it here.
oh my... I found it actually can play when I tested again to see the err output... sorry to bother you for my carelessness, and thank you very much:-)
and also, the only problem is it'll take 5s~30s before start playing after click, which made me thought it couldn't work for a year or two... I should say it's much slower than rar reader(see deadbeef archive reader i packaged in aur, you can try it:-D)
I doubt if it's abnormal, so would you mind sharing with me that how's it going on on your computer? thanks in advanced:-)

Power Manager idle timers don't work correctly when set to dim the display in 15 minutes

Instead of dimming the display to 0 on AC power, Power Manager dims it to 4, which is a normal setting when on DC power. Then when the laptop is resumed by tapping a key, it "restores" the brightness to an incorrect setting of 15, and a few seconds later back to 8, which is the correct setting. I haven't noticed this problem when setting to dim the display below 15 minutes, but the restoration of screen brightness onscreen notification is displayed twice in both cases.

Hey there lenssd9,
It seems strange that the Power Manager would be behaving this way, although speaking with some colleagues they also have encountered similar occurences- but instead describing it as if "the engine were warming up with a high idle, and then returning to a standard idle."
What I can recommend is to first, ensure that your Power Manager Software is up to date. And then try adjusting the configuration within the Power Manager. If you will, see if you encounter this with a idle display under 15 minutes.
Thank You lnssd9, I look forward to your response.

[SOLVED]Login manager in KDE 4.3 does not work!

This is a fresh install (just two days old and installed KDEbase just yesterday), and almost everything is working like a charm the only glitch I have experienced till now is that the login manager module in System Settings is not working as it should be. When I click on its button I know that it should normally ask me for my password but it does not do that and therefore when it opens up all the settings are greyed out and thus unchangable . Is this a bug or am I missing something (Anyone else experienced this!)?
Also, although not related to this topic, can somebody tell me where to find the setting for making windows shift to different workspace while dragging them through the edges of the screen. I'm sure I found this setting under Window Behavior>Window Behavior module in Kubuntu but it is nowhere to be found on the Arch KDE.

As nobody answered this question, I guess I'll just mark this thread as solved as even after a lot of search I'm unable to find the preference and so none of the arch users here know about it as well. I think that feature was kubuntu specific and as Arch ships vanilla KDE I think its useless trying to find it here.
Anyways thanks for the help guys

[SOLVED] Automount CD or DVD doesn't work (consistently)

Problem with mounting CD's / DVD's and Device Notifier
DVD's are not mounted in /media/, and the Device Notifier does not show them.
CD's (which aren't actually mounted) I can always access in Dolphin with "AudioCD:/", but Device Notifier rarely pops up (maybe 1 out of 10 times).
facts:
- No device listing in /etc/fstab for DVDROM
- File in /etc/hal/fdi/information/<device>.fdi has bool set to 'true' (and I tried deleting the whole file as well)
- HAL notices that the CD / DVD is inserted (with lshal -m):
storage_model_DVDRW___DVR_K17B property storage.removable.media_available = true
- Tried deleting .KDE4 profile, but that didn't change anything,
- I've got Ubuntu 10.10 installed on the same hardware, and it mounts / shows everything without problems (conclusion: problem is not hardware-related). Ubuntu doesn't use HAL.
- SystemSettings -> Removable Devices -> Automount on Attach is enabled (just in case),
- USB flashdrives and external Hard Disk are mounted and shown by Device Notifier without problem.
- I do get these errors with cat /var/log/errors.log | grep sr0, but they also appear in the rare event when a CD or DVD is actually mounted and shown by Device Notifier:
DVD:
Sep 7 13:55:05 localhost kernel: end_request: I/O error, dev sr0, sector 4096
Sep 7 13:55:05 localhost kernel: Buffer I/O error on device sr0, logical block 1024
Sep 7 13:55:05 localhost kernel: Buffer I/O error on device sr0, logical block 1025
CD:
Sep 7 13:58:57 localhost kernel: end_request: I/O error, dev sr0, sector 0
Sep 7 13:58:57 localhost kernel: Buffer I/O error on device sr0, logical block 0
Sep 7 13:58:57 localhost kernel: Buffer I/O error on device sr0, logical block 1
(the CD in this case was actually shown by Device Notifier normally! So these errors don't seem to have anything to do with it)
I don't think this is HAL - related, so it must be udev, dbus (not likely), or maybe KDE / device notifier.. ?
How do I troubleshoot this? Any suggestions?

Problem solved:
At one time, I was using the [testing] repo. Removed it from pacman.conf a week ago, because i wanted to get back to the stable packages. I re-installed all the older versions of the packages that are in core / extra and that pacman warned me about. Did not get any further warnings after that, so I assumed everything was fine, and the rest of the system was stable and working just fine. But something must have been broken, see the above. In other words: I messed up things without knowing about it. :-S
Today I added [testing] again to check if this would solve my problems, and it did!
Or... is it just the newer version of udev that is in testing at the moment. :-) Who knows.
This leads me to my next question: how can i safely disable [testing] and return to stable packages, without breaking anything?
