Ubuntu :: Power Profile/power Management App?

May 28, 2010

On the last release, I had this app installed where I could pick my power profile. I could use power conservatively, and performance would suffer a bit, but longer batt life,or I could have it automatically detect, or I could have the apps use all the power they want and then some. I'm looking to reinstall that app. What was the name of it?I can't remember, and so far, can't find.

If i set it to an 1 it still like every 5 minutes turns off my screen. Im running 9.10 on a toshiba satellite with an intel graphics card.

Ubuntu :: Power Management Has No Effect?

May 15, 2010

I have a laptop with 10.04 installed. When it is plugged in with AC Power, the screen fades black after a few minutes and locks up after about 10 minutes (shows a dialog for passwd when back).This gets really annoying when listening a movie or just reading text.System->Preferences->Power Management is set to "never" for everything.gconf-editor->apps->gnome-power-management is set to "0" for everything finishing with *_ac.

Ubuntu :: How To Disable Power Management

Sep 22, 2010

I am wanting to completely disable Power Management, can I do it through the GUI? I am a former OpenSuSE user & am use to YaST. So it is a little hard finding ways to edit some settings.

Ubuntu :: Power Management In Kubuntu 10.10?

Oct 12, 2010

I just did a fresh installation of Kubuntu 10.10 on a laptop last night, which has a 1.6GHz Intel Core Duo CPU.

I was very disappointed to find that there appears to be no way to configure CPU frequency scaling in the System Settings. There were options for this in 10.04.

I prefer to have the CPU running at maximum speed when running on A/C. In Maverick, however, I have had to resort to installing cpufreq-utils, and setting the CPU cores to 'performance' from the command line.

I like this laptop a lot, but even many simple games run sluggishly if the CPU cores are not set to run at max GHz. (As a matter of fact, this machine is much more sluggish even with CPU cores running at maximum in 10.10 than was the case in 10.04.)

I wonder why such an important option would have been removed from the power management settings?

Ubuntu :: Power Management Not Suspending?

May 30, 2011

Ok, I am running a file server that can be accessed throughout the house. I was able to successfully wake from suspend and it works beautifully. Now what I need the computer to do is go to sleep after lets say 30 minutes of inactivity so that I never have to touch the computer and it will use minimal power until I need it.

Anyhow, I tried to set the settings in Power management and the only thing that happens is the display turns off. the suspend on the desktop works fine, I can type in sudo pm-suspend and that works fine. but the computer just wont go to suspend automatically by way of the power manager.

I have tried changing the /etc/pm/config.d/00sleep_module to say SLEEP_MODULE="uswsusp", but that only made the computer go into some crazy linux mode that I had to reboot from. I had to change SLEEP_MODULE="kernel" (actually, I left it blank as it is the default).

I also turned off my screensaver so there wouldn't be any confusion from that.

I also ran cat /var/log/pm-powersave.log and I got a long list with the following being one of the main texts that kept repeating. "/usr/lib/pm-utils/power.d/sched-powersave false:**sched policy powersave OFF"

Ubuntu :: Power Management Screen Not Turning Off?

May 12, 2010

I have an issue where the screen on my laptop will not shut off with the power management tool. The Default Power Manager does not have an option for this.My screen will go blank after a set amount of time, but the lcd-backlight will remain on. I would want the power manager to shut the screen off completely (including turning off the lcd backlight) without shutting down the computer it-self. So the computer can continue to do what I left it to do in the case I forget to close the lid. With the screen shut off completely, will preserve the life of the back light and reduce power consumption.

Is there a better power manager app that will allow me to do this a tweak to the existing default power manager that will allow the functionality I am seeking? laptop was perfectly able to do this under a win-xp environment, so I know the machine is physically capable of doing this. Note: My WinXP OS and Ubuntu OS are on seperate physical drives so there is no dual boot issues. So when I am using one there is no trace of the other present

Ubuntu :: 10.04 Missing Power Management Buttons?

Jul 6, 2010

when I boot up ubuntu, the suspend and hibernate buttons will be missing and the alsa stuff wont work. When I select shutdown or restart or log out from the power menu ( the one that's missing the 2
buttons) it only logs off the user. I've tried reinstalling the kernel and updating grub for a solution to no avail. The only way to shutdown the system when this occurs is through a sudo halt command in terminal. I may have to use the command a few times until the computer will boot with sound and all of the suspend/hibernate buttons in place.

OpenSUSE :: Power Management Is Incompetent

Mar 21, 2010

I have selected to power down the monitor after 30 minutes, and suspend the computer after an hour. It does not work. With Beagle not running (more below), the monitor powers down after 30 minutes as expected. But then later (probably after an hour?) it powers up again and stays that way. Not exactly what I envisioned.I have removed Beagle from the set of running processes. The process list ("ps ax") shows Beagle as a serious consumer of CPU time, far more than any other process. (At termination it was at 500:00; the next most hungry process was /usr/bin/Xorg at 10:00. Most barely get over 0:01.) It introduces these problems:

1. after some amount of system idle time (it is about 5 - 10 minutes) Beagle starts consuming vast wodges of CPU time. I have dual core AMD 5200; both CPUs run up to about 70% usage until I do anything, like move the mouse. Then the usage drops back to the usual 5 - 10%.
2. When Beagle is thrashing the CPUs, the power management monitor thinks the system is busy. And powers down nothing.

OpenSUSE :: Power Management Options For UPS?

Sep 29, 2010

I've attached a UPS to my server through USB. and sure enough up came a tab in Power Management Preferences for the UPS -- great.

There are power low options as follows:

"When UPS power is low"
"When UPS power is critically low"

The UPS sends a message to the computer when a threshold you set in the UPS is reached, in my case 25% of battery left.

The obvious guess is that this warning from the UPS is the "When UPS power is low" however, I don't know. It's just a guess.

Looking further at the data I can get from the UPS the battery data is as follows:

battery.charge: 100
battery.charge.low: 25
battery.charge.warning: 50
battery.runtime: 760


However, again, that's just a guess from what would make sense.

So my first question is, is there a way to know this information, and is there a place were these critical points are set, or are they all from the UPS. I'm guess there are some settings somewhere because not all UPSs are going to be able to supply this information. Some may only supply a battery level or some just a warning message so there must be some configuration for this somewhere.

My 2nd question is a probably a little harder to know the answer to. After getting this to work I wanted the added functionality of nut so I installed it and got it working and it uses the On UPS Power panel as far as I can tell.

Through all the nut documentation it talks about powering down on once the battery level reaches the critical point (I assume that is "When UPS power is critically low"). I don't see anywhere however where it mentions handling "When UPS power is low" so now the question comes up, will it have any effect at all with nut installed, i.e. what will happen?

Of course I can just "pull the plug" and start finding this stuff out but Linux is all about having the information and "knowing" (assuming all works as it should) I am asking to find out where this information would be -- and become smarter for it

General :: Power Management In Openbox?

Jun 16, 2011

I'm fairly used to working with Fluxbox.There,if I want to let myself suspend the computer, all I have to do is add something like Code:[exec] (suspend) {sudo /usr/sbin/pm-suspend}to my .fluxbox/menu and it works like a charm, after having added me to the sudoers. I nstalled openbox earlier today because I was having some font rendering issues in flux and I've been trying to find a way to add something similar to my menu without success. I added this to .config/openbox/menu.xml:

<item label="suspend">

Slackware :: Power Management On Laptops?

Apr 17, 2010

I've got a new netbook - Dell Inspiron mini 1011. I have installed slackware 13 on it. According to dell's website its battery should last up to 9 hours:Quote:Mini 10 offers up to 9.5 hours of battery life1 to keep you on the go.I understand that it depends on a variety of factors and these are just testing estimations that will probably never be achieved IRL.For 95% of the time I don't run X on it. Just emacs (gnus), nethack, elinks. If I do run X, it's fluxbox. The average battery time is 2hrs - 2.5hrs. I understand that Slackware 13 is not designed specifically for netbooks, but 2hrs is way off the 9-hour estimation. Either the battery is faulty, or it's the power management issue. Before I deal with the battery, I'd like to ask you for some suggestions on improving the power management. The acpi and acpid are installed on the system. Are there any packages that would improve the battery performance? Or perhaps some config options?I believe that recompiling the kernel would improve it, wouldn't it? What options I'd have to set/unset?P.S.Unfortunately, once I checked the netbook is ok, I removed WinXP that came with it, so can't compare with it.

Ubuntu / Apple :: Macbook Pro 5 - 4 Battery / Power Management

May 2, 2010

I am having several problems with what i believe to be gnome-power-management. Power management will randomly say that either i do, or don't have a battery. This means that the icon in the notification area does not appear, and I can not access the settings for on battery power. also, when i tell Ubuntu to suspend, it just goes to the screensaver and nothing happens. conky is still able to read the battery just fine, its power management thats having problems.

Ubuntu :: Power Management Working In Failsafe Mode Only

Oct 8, 2010

Whatever settings I use in the power manager, (Ubuntu default Gnome Power Manager) nothing appears to change. Screen brightness does not change when moving the slider, but is reduced after 5 or 10 minutes (haven't timed it. Probably whatever is default) of inactivity, even though the reduce screen brightness checkbox is unchecked. The latter is pretty annoying when watching online TV streams, especially since the video also exits full screen mode when the screen brightness is reduced.

The weird thing is, as the title implies, that when booting in recovery mode with FailsafeX the power settings seems to work. At least the screen brightness varies as the slider is moved I should probably mention that it is possible even in normal mode to adjust the screen brightness by using the buttons for adjusting screen brightness on my laptop (Fn + arrow up/down)

Ubuntu :: Root Script At Startup For Power Management

Apr 25, 2011

I'm trying to enable a few of the powertop suggestions at boot. My plan had been to put the changes in /etc/rc.local, but it appears possible that some of the changes are happening too early in the boot process to take effect. Specifically

echo 1 > /sys/devices/system/cpu/sched_mc_power_savings and cd /sys/devices; find . -name link_power_management_policy -print0|xargs --null -n 1 -I{} -t bash -c "echo "min_power" > "{}""

both work if run with sudo permissions after I've logged in. where to put these such that they'll take effect on boot? Or can I put a sleep in the rc.local?

Ubuntu :: Disabling Screensaver And Power Management In XFCE?

Jul 22, 2011

Because Ubuntu 11.04 is a bit heavy for the capabilities of my older desktop hardware, I am in the process of switching over to Xubuntu 11.04 going forward. I found the "sleep inhibit applet" very useful when I was using the Gnome DE, and was searching for a replacement in XFCE that doesn't require installing a bunch of Gnome libraries. I found a description of "caffeine" as a utility that seems to be what I'm looking for, but when I added the caffeine ppa to my repositories, and select it for installation in Synaptic, it wants to add a long list of Gnome-related components. Is there any quick way to temporarily disable the screensaver and power management functions in XCFE that doesn't depend on Gnome?

Fedora :: Power Management Preferences Not Working.

When I change the "Put display to sleep when in active for" it seems to make no difference. The screen goes to sleep when it wants. Some times in the middle of watching a dvd (after about 10 mins when it is set to 1 hour).Could this be done by terminal, perhaps there is a problem between entering in the GUI and actually telling the machine.

Fedora Installation :: No Power Management After Upgrade?

For example, when pressing the power button, there is just a 'Cancel' button (no button for shut down, suspend, hibernate), in Gnome menu there is no possibility to shut down, and in 'gnome-power-preferences' most options do not work at all. For example, there is no other option than 'Blank screen' for 'When laptop lid is closed' action. When starting 'gnome-power-preferences' with '--verbose' parameter, I get following error messages:

It's seems like screen energy saving is set permanently for couple of minutes, don't matter what time do i set, it just discards my settings, even they are correctly viewed in the gui.
