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.
View 1 RepliesI was going through the article given here :- [URL]. Now my question is how to do this in linux ?
View 2 Replies View RelatedThe topic of this thread says it all.
View 9 Replies View RelatedI'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?
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.
View 2 Replies View RelatedI 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%

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?
View 2 Replies View RelatedWhat 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.
View 4 Replies View RelatedI am currently running a Debian 4.0 (etch) PC and I can't upgrade to a newer distribution for legacy software reasons.
It is currently running on Kernel 2.6.18-4-686 and I would like to upgrade it to Kernel 2.6.22-3-686 (whilst keeping my current Debian 4.0 Etch installation). Does anyone know how this could be possible?
Prefereably I would like to instal Kernel 2.6.22-3-686 along side my current Kernel 2.6.18-4-686 with the option to specify which kernel to use when booting.
I have some general question with with quite an impact for the system I use I have a media server with 2 raid1 mirrors of 2 1 To disk aggregated with lvm and used by a big 2 To ext3 partition.A few days ago, munin (awesome!) started to send me notifications about smart attributes of some disks.

regarding reliability and disk longevity, is it recommended to have them spin down while not used (most of the day, as these are storage unit for movies, pictures, documents..) or let them spin whatever.. ? Those are WD green and according to Tom' Hardware, the consumption is only slightly greater in idle compared to standby. The other question, (boat one as we say in french ) what is the best configuration here ? My 2 raid 1 stripes, or a raid 5 ? I know that two disks kill the raid 5, and they have to be of the same stripe to kill the lvm on the raid1, but what are the odds ?
I cannot get ksh to have super tab completion power. Is it possible? I would like

I am trying to figure out where the harddisk power management can be found in Squeeze. Before it was in the scripts under /etc/acpi, but in Squeeze it's not. I'd like to be able to change the hdparm -B value from 128 to 200 when using battery.
View 3 Replies View RelatedI decided to upgrade my Asus Eee 900 from Lenny to Squeeze, to fix some issues that I was having. I did a fresh install using the beta1 netinstall cd image, and now my system is mostly working as I'd like it. Overall it seems quite good, and it even boots much faster than it did with Lenny.
I've encountered a problem, though. The suspend key doesn't work. I installed the package 'hibernate', and now the system can suspend via a command (which seems to work properly, although I haven't tested it extensively). I've noticed that the squeeze system doesn't have a command that my other Lenny systems do, 's2ram'. And I've noticed also that a package, uswsusp, which seems to be related to this kind of thing, can't be installed because it's not in the repositories: Package uswsusp is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'uswsusp' has no installation candidate
I disable that from the gnome power management utility screen go black after 10 minute. It's very annoying since I cannot watch a movie in that way!
View 6 Replies View RelatedDespite having the Gnome Power Manager set to put the display to seep after 30 minutes, it always happens after 5 minutes. The display will go blank but still lit, and then it powers off after the 30 minutes. Surely, if I set it to 30 minutes, the display should power off then, and not just blank after 5? I have no screensaver packages installed so it's nothing to do with that.
View 2 Replies View RelatedUsing Openshot, flowblade, or Kdenlive, when video gets rendered into mp4, it comes out at increased speed, both audio and video (seems like double speed but could be a different ratio)
When I play the exported mp4 with VLC for example, it shows the proper video length, not shortened. The video plays at high speed and for the second half of the video it just shows the last frame of the video until it runs out of time.
I have used Openshot extensively and have never had this problem, so I installed all the other video editors I could, and the problem persists (pitivi has a dependency problem so I haven't been able to use it).
I have tried several video players as well, all doing the same (VLC and Smplayer)

Is it possible to add menu entries for older kernels to boot instead of the latest?
I have tried this in Ubuntu 10.04 and it hasn't worked.
This used to be possible with ease in grub legacy.
I copied the current menu entry from /boot/grub/grub.cfg and pasted it in the /etc/grub.d/ 20_custom file.
Then I changed the kernel number to the older kernel number and the initrd number too. #update-grub puts this entry into 'grub.cfg', but it doesn't work.
I get:
The old kernel is in /boot as well as the respective initrd and config files.
I use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?
As I am trying to understand if there are any advantages using a kernel optimized to have low latency for the desktop, it would very helpful if anyone using one could give me his opinion. I read about the liquorix kernel and found a controversy and used google to find more information.
View 2 Replies View RelatedRunning debian sid. I have the Debian 2.6.32-trunk kernel installed and the liquorix kernel.
I use sgfxi to install the nvidia driver. Normally sgfxi allegedly strips out all prior nvidia, using both the nvidia uninstaller and purging any debian nvidia packages.
Today when I updated the liquorix kernel and reinstalled the drivers for the new kernel, it was still installed in the old kernel. Normally it is just installed in one kernel.

I guess the questions is, is this a new feature or just some weird glitch? Also I only get the nvidia splash on the Debian kernel and not on the liquorix kernel.
Such as here [url] this is the debian installer with a kernel 2.6.26 for squeeze.
Where are the archive on debian.org for those boot.img.gz images, with all different distro / kernels?

What seems like forever ago now I tried to install Linux on this Intel 82855GME chipset laptop I was given. I started off with Fedora because it's what I'm most familiar with, unfortunately the live disk would crash at GDM so I could never get anywhere with it. Even doing a console based install would crash, but it at least pointed me in the right direction, it seemed the kernel was crashing for some reason (see image)Fedora livedisk crashlivedisk-error.jpg (95.96 KiB) Viewed 695 times
View 14 Replies View RelatedI'm running kind of a mix between Wheezy and the occasional package from Sid. I've got the 2.6.32 kernel installed, as well as 2.6.38 and 2.6.39.
With the first kernel (2.6.32), my sound is normal, everything works fine. With the latter two, even using the same driver, my sound is quiet even with the volume up all the way, not to mention that somehow the available volume controls change along with this update. I was wondering if anyone else has experienced something similar, and if they managed to fix it or work around it without just booting into the older kernel?
Have not been installed correctly.

Booting into recovery mode and different kernels doesn't help.
