One of the PC having Ubantu gets disconnected automatically from the network.As we do in normal windows is that we get to the device manger and select the LAN card properties and check off the power management check box similarly how can be do this thing in a linux OS.
View 2 RepliesI 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.
View 2 Replies View RelatedI've just installed openSuSE 11.2, and I need to disable the feature that causes the laptop to suspend when you close the lid (and it's plugged in to the wall). I've already done this for my user profile, and I've attempted to do it for the root profile, as well, but when the GDM login screen is shown, the laptop still suspends when you close the lid.

I want to disable display power management.
I tried to achieve this by disabling 'Enable display power management' checkbox in the 'Configure Desktop -> Display -> Power Control' KDE configuration dialog. That didn`t help and display still goes into standby mode after some period of inactivity. Also, I tried to disable dpms functionality by calling 'xset -dpms'. That didn`t help too. Note that 'xset dpms force standby'
I have recently loaded Ubuntu 9.10 which runs perfectly, except for the power management system.I go into the GUI power management screen and tell it to use the screen-saver after ten minutes, but NEVER suspend/ hibernate but it suspends/hibernates anyway,sometimes after an hour, sometimes hours later.Is it possible to keep the screen-saver but disable the rest of the power management system?
View 2 Replies View RelatedI just upgraded to 10.4 and there is no longer an option to "Do Nothing" when the laptop lid is closed. Since I use a dock and external monitors, this is a critical setting. If I choose "Blank Screen", it blackens my externals... and I certainly don't want it to suspend or hibernate just because I dock the laptop..

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.
View 2 Replies View RelatedI am facing a problem with the management of my network card after installing Ubuntu 11.04 32-bit Desktop edition.
There are two Network Cards and one USB adapter which I'd like to drive:
- Ethernet controller Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet (rev 02)
- Ethernet controller Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
- Realtek Semiconductor Corp. RTL8187 Wireless Adapter
Actually I need the wireless adapter to connect to the AP, so both of the ethernet card should be disabled. Infact, when I try to access to the AP I must disable the eth0 card by using (sudo ifconfig eth0 down), otherwise the route assigns the default gw (192.168.1.1) to the eth0 device and the network is useless.
I am using ubantu 10 and broadband where userid and passwd has been configured in router box. So when I connect this from windows its automatically connected (using ppp0e and dhcp), whereas in linux it could not connect.

View 1 Replies View RelatedI 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.
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
[Code]....
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
Alright this is not a huge issue but a rather annoying one. I hook my laptop up to my lcd to watch movies all of the time. The problem is though I have selected and reselected many times for the screen to not power off after so many minutes of inactivity. But for some reason it doesnt work. 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.

View 1 Replies View RelatedI 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?
when i get the Graphics device driver on, then the power management not work. it can not change the CPU frequencies, and it can not change the LCD backlight and save the change. I try a lot, install laptop-mode-tools,and change thd setting, it still not work...

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"
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:
Code:

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.
View 14 Replies View RelatedThis is very likely a silly question but .. where is the power management setup in KDE? I have set it up before in Slackware 13.1 but now that I'm running 13.37 I'd like to set it up again but can't seem to recall where to set it up.

I've got openSUSE 11.4 64 bit system with stable 2.6.38 kernel and KDE 4.6.3. Problem is that when I want to change some settings in the power management (like brightness, screen energy saving time-off, display dim), they doesn't seem to save, even after the X restart and full reboot. 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.

View 2 Replies View RelatedOn a couple of Linux laptops I have the built in screen never turns off it's backlight, regardless if a 'black screen' sort of screen saver is activated (this both for a laptop running an X-based desktop as well as for a laptop only having a text console) or if I even close the lid of the laptop (looking carefully in the dark, I can tell that the screen still has the backlight on, even if the laptop "know" it is closed).
This is a bad thing for a couple of reasons:
It wastes power
It generates heat which when the laptop lid is closed increases the cooling need (the fan goes on more often etc).
Backlights have limited lifetime like all electric components and IIRC, the less a backlight is turned on, the longer it will last. So, what is the best approach (considering a Gentoo with a 2.6.36 kernel) to remedy this? I recon that there probably are two approaches:
One for text-only laptops which never displays a desktop, e.g a laptop sitting there acting like a firewall or server
one for those running a Gnome/KDE/XFCE desktop (and a SLIM or GDM display manager).
The laptops I have in mind is a Dell Latitude CPi (built 1999, yes, it is from another millenea), a Compaq Armada M700 (built 2001) and a Dell Latitude D630. If this can be accomplished only by configuring things in the Linux OS (be it kernel setup or editing config files) without touching anything in BIOS, that would of course be preferable.
