Fedora Hardware :: Power Consumption In Runtime Level 3?
Mar 21, 2010
I'm very curious about something. I like to use my command line as much as possible. So, most of my work and usage of my computer revolves around the command line. In such a case I could work without having to use any graphical interfaces. My only current limitation is WLAN connection isn't working for me, but that belongs in another thread and something for me to do for now.
My question is, Is it worth it in terms of battery life to work in level 3 when running a laptop on a batter? What sort of extension to the life would one expect?

According to Phoronix [URL]... aspm&num=1 (which seems to only test Ubuntu kernels) the problems should affect all users of the affected kernels, including Debian's, but that article provides a fix. I don't remember anyone here mentioning lower battery life and increased heat on their mobile platforms, though.

I have installed a new PC system
- OpenSuSE 11.3, 64bit
- AMD Phenomen II X4
- ASUS M4A88TD-V Evo/USB3
- 3 hard disks
- etc.
After start-up with runlevel 3, no applications running, network is up, the overall power consumption of the PC (without monitor) is ca. 70 Watt. After some minutes the monitor goes to power saving (terminal mode, runlevel 3 !), but the power consumption rises to 120 Watt! After pressing a key on the keyboard (e.g. Num) the monitor leaves the power save mode, shows the login screen, and the power consumption falls to 70 Watt. In parallel I have investigated the system via ssh and running top, but I have not observed any abnormal operation. I looked into /proc/acpi/* but I did not find something unusual.

my SheevaPlug just died, and I need to look for new device to replace it. My goal is to build a fanless, low power consumption, linux server. Currently I am thinking of purchasing a QNAP NAS device (TS-110 model) and installing Debian on it.

I am working on a traffic surveillance project which performs various image processing tasks with a number of visual sensors and a computing platform. My basic task in the project is the power optimization/management. I am using a ZOTAC-IONITX computing platform (Intel ATOM CPU + NVIDIA ION GPU). The problems that I am currently facing are:
I am unable to model the power consumption of various components e.g., processor, GPU, hard drive, memory etc, since there seems to be no way to measure the power consumption of individual system components. Since I don't have a power consumption model, I cannot come up with a power optimization algorithm. I am currently working on Linux. Is there any way to measure/model the power consumption of individual system component?
I have already checked powertop. It doesn't tells the power (watts) consumed by a component (e.g., microprocessor). It just gives information about the power state the processor is in (However there is no way to change the power state by the user) and the processors that cause processor to wakeup.

Judging by the number of responses (close to zero) to other threads about powertop on this forum, I have little hope in getting any answers. However, I do not know where else could I ask. PowerTop tell me that even after applying almost all the tips and tricks from lesswatts.org, my laptop still consumes over 72 Watts while idling.
Code:
< Detailed C-state information is not P-states (frequencies)
1.60 Ghz 0.0%
800 Mhz 100.0%
Wakeups-from-idle per second : 451.1 interval: 10.0s
Power usage (5 minute ACPI estimate) : 72.5 W (0.3 hours left)
Top causes for wakeups:
[Code]...
Suggestion: Enable USB autosuspend by pressing the U key or adding usbcore.autosuspend=1 to the kernel command line in the grub config This is when I am not touching the laptop. When I am surfing the web or listen to music, it goes up to 2000+ wakeups! How do I cut it further? I am getting like 20-30 minutes max on battery and this is unacceptable cause in Windows I get at least 3 times that.

I'm using Ubuntu 10.04 LTS on my HP ProBook 4510s.[URL]... On Windows XP, the battery usually lasts me over 4 hours but on Ubuntu it barely last 2 hours. How can I reduce power consumption and prolong battery life while running Ubuntu on my laptop?

What my situation was before the problems:
-I dualboot win(xp) and xubuntu(11.04)
-No problems whatsoever except for the fact that power consumption was higher on xubuntu.
Then i read something that said that the kernel i was using was effectively having power issues and that it could be fixed so in went into the terminal and nano'd the grub config file and update-grub'd with the addition i had read all over the internet. When i rebooted it seemingly had worked but once i opened a ..... video it didn't react to anything (i'm 99% sure kernel panic since there was no hdd movement). So i forced it to shutdown and when i got back in again i nano'd the file again but for some reason i didn't only remove the power stuff but I also removed the quiet splash. Once i had rebooted it would suddenly ask for username and password twice.
once the older looking menu an then the newer looking one with the fancy bg). The first time i got in okay but afterwards i could only get in as root. I thought i had simply forgotten my password but i ran passwd myusername as root and it didn't work(only when i typed something random it gave the wrong password message). As root i also can't edit the users and groups(when i open it it stays grayed out). how do i fix this. If i will lose my account anyways then how do i get my files/bookmarks/... of of it.

So I've come across several tips to optimize battery life on Linux. [URLs]. In addition to undervolting, I would like to underclock. Is there a way to control CPU speed outside of the BIOS via some software control in Linux... or some sort of boot manager? I would like to boot to linux using underclocked speeds and have Windows running full blast. Is there a way to run Linux completely in RAM? I have read that saves on power consumption from the hard drive.

After installing Fedora 14 and being satisfied with the behaviour and the packages installed for it, i want to replicate the same installation in a few more PCs, so i installed Revisor to make with it an iso file that reflects my actual installation.
The problem is that if i run the software from Applications->System tools->Revisor, nothing happens after giving the user password.
Then i run it from a consele and this error is produced after giving my password: "Cannot find anaconda-runtime in /usr/lib/anaconda-runtime"
But anaconda is the environment used for installation, so it is installed from the very begining. Why this happens?

I am currently having issues with system freeze when unmounting portable hard drives. This happens almost every single time. Normal USB sticks are fine and do not produce the freeze. I am using kernel 3.0.0-rc6, however the issue also persists when switching back to 2.6.39. This is the error message i get when freeze occurs, reverting to terminal output:
WARNING! power/level is deprecated use power/control instead

I run V11.1 on a minimalised install on a stick with TWM, no KDE at all but I cant get rid of the screen shutdown after about 20 minutes. Also I have several other boxes with v11.1 with KDE and still cant get rid of these screen shut downs.I dont believe this is coming from the bios in these machines. they are all Intel D945 MBs with some sort of Nvidea cards.
My app normal runs with no user mouse or input and is pocessor intensive.I would like to retain the power shutdown and reboot capability from comand line.I realise its not as simple as pulling symlinks of of the init levels in the new complicated distros, but I was suprised the non kde twm install still shuts down the screen.So I want a low level level fix that will remove anything kicked off by init that will derate the system performance or turn off the screen.

I am trying to install the Matlab 7.5 compiled runtime for 64-bit Linux (MCRInstaller.75.glnxa64.bin) and keep getting a "No Java Runtime Environment(JRE) was found on this system." error message.
I understand the JRE is bundled with MCRInstaller and will self-compile/install. However, I don't have admin access, could this be the source of the problem? If so, how could I fix it (not sure how to direct it to install locally without going into the source code)?
I got around this error before, but stupid me didn't write down what I did and I forgot.

Hi Guys,
here is my scenario:
I am running F10 x86_64 with Nvidia Quadro FX 3400.
I installed the drivers and it worked just fine. No errors generated according to Nvidia log files.
However, while in run level 5 when I try to switch to run level 3 by typing "telinit 3" or "init 3" the X server goes down and I get a blank screen. Same thing happens when I try to switch to a different tty session by <ctrl>+<alt>+F2 (or any F key for that matter).
I also noticed that when I shut down my system I can't see any more the screen where services are shutting down and their status ([OK] or [failed]).
Would appreciate your help on solving this issue.

I have been using wine to run a mapping application called Tracklogs. It provides Ordnance Survey 1:25000 mapping that can be printed as well as upload routes to my GPS.
It has worked perfectly since Fedora 8, I last updated wine appDb in January 2010 reporting that it was working with Fedora 12 and wine version 1.1.32.
Since wine has been updated, I now get an error dialog "Microsoft Visual C++, This application has requested the Runtime to terminate it in an unusual way. Please contact the applications's support team for more information".
As far as I am aware tracklogs does not use Visual C++ Runtime, so I am not sure why it is even installed. It is a clean install of wine and this is the only application I have.
It has worked consistently for over 2 years and 4 versions of Fedora and no doubt multiple updates of wine, but at some point recently something has changed with wine that causes this error. Have they included Visual C++ Runtime by default? Is there anyway to get rid of it?

I've been able to kludge a kill script which finds the correct pid for the kdeserver (or gnome server) after my system comes up in run level 5 so I can drop back to run level 3 mode. Lots of experimentation showed me that using telinit 3 and telinit 5 would occasionally leave the video memory in a mess and I would have the black screen of death.
I set the security parameter setting to autologin for me since I am the only user of my machine, but I still have to kludge the default setting under sysconfig (the DEFAULT_WM) under Window Manager to pick a certain window manager, so it takes time to manually switch the desktop.
Right now I can leave the gui and drop back to cli, but painful experimenting showed me that killing the X server is a no no. Right now I kill the kde server, which sends the SIGTERM to the X windows manager, which then figures out that it has to shut down.
Questions: Is there a better way of doing this? Apparently openSUSE figures that we have multiple users logging into the gui desktop, so the gui is always kept running and a login window with the desktop manager option forces the user to login in. With autologin, this never happens, but no choice of desktop is possible on the fly.
Can some type of script be set up to painlessly enable this to happen? And what is the best way of bringing either the Gnome or KDE desktop manager down gracefully? I do get lots of error messages as the system attempts to recover and X shuts down. It appears that apparently the single user with autologin is left out in the cold.

I want to install a software called TinyOS which is an operating system designed for wireless sensor embedded networks in my account. The problem is it has instructions to install the software as an administrator since i'm not an admin of the department network i can not able to install. Is there any method to install this software as an user level rather than admin level.

hello everyone, im having a problem when my computer enters in the run level 4 as the default when i start slackware. The strange thing is that it not seems that is a X window problem, it looks like more like a configuration problem in some part of the kde script to initialize the log in, because if i manually start the X service it works fine, i dont know what is the source. Thank you in advance for the help.

I recently gave the boot to Windows and installed Fedora 10. Under Windows, I was using VirtualBox for all of my virtualized computing needs. I had set up a virtual network with two virtual machines - one running Windows Server 2K3 and the other running Windows 2000 Pro. I could run both VMs at the same time and still use the host OS. Now I am trying a similar setup under Fedora, I am using VirtualBox to run Server 2K3 and Windows XP. The problem I encounter is that when I run one VM, one of my CPU cores rockets to 100% usage and the other hovers around 40% - 60% usage. Is there a way to enhance performance so I can run both VMs at the same time? Third, what would be the effects of me installing the Xen runtime environment package or the Xen emulator for KVM?
System specs:
OS: Fedora 10 x86-64
CPU: Athlon 64 X2 3800+ (Toledo)
RAM: 2GB PC3200
GPU: GeForce 7600 GT XXX

you can find a cutout of an output generated by "iwlist s" command for a cell. Does anybody know what Quality, Signal level and Noise level mean? What is the definition of them? I searched for it and could not find good information on it. What do these Extra:*** fields for? What does it show in the example above? How were those values computed?

I have a directory that has a another directory inside it. The top directory is rather redundant since it only contains the one other one. Is there a way to delete the top level directory and have the contents simply "move up a level"?
