Thread: OpenSuse 11.4 high CPU usage on scrolling

  1. #1

    Default OpenSuse 11.4 high CPU usage on scrolling

    Hi,
    as the title says my CPU goes on C0 state (100%) on every scroll and then returns down after a couple of seconds.

    Is it normal?

    I've checked this with powertop (and with my ears because I hear the fan noise...)

    Default Απ: OpenSuse 11.4 high CPU usage on scrolling

    Only when you make boot and turn on your pc?

    No, every time that I scroll with touchpad or mouse on every application ...

    I had that problem when I was running 10.1. It was due to a mismatch between the display and the graphics resolution. I switched to an nvidia driver, and that fixed the problem.

    I never had that problem in 11.0, 11.3 or 11.4, so presumably the default linux drivers now handle my graphics card and display correctly.

    I'm guessing that you, too, are having a video adapter problem.

    No I have not problems with my graphic's drivers. I have AMD RADEON 6990 in my pc and I wait drivers for it. Which graphics card do you have?

    I have nVidia GeForce 6150 LE. But I am not currently having a problem. I did have a problem back in 2007.

    Now you have problems with CPU temperature?

    -=welcome=- new poster..

    but since we don't a crystal ball we don't know much about what you have
    there...so please give us some more info:

    what operating system and version are you using?
    what desktop environment and version?
    are both running in a VM or directly on the machine?

    what graphics chip?
    have you installed the best driver? see http://tinyurl.com/37v9y7m

    you say it happens in _all_ applications...would that include Firefox,
    Thunderbird, KMail, Evolution, Opera, Konsole, OpenOffice, Okular, GIMP
    and in a terminal a long list in 'less'?

    if so, then in addition to checking your graphics driver i'd check with
    the system manufacturer and see if there is a BIOS update or recall..

    by the way, you didn't mention if yours is a netbook or a rackmounted
    server on the other side of the earth that you are accessing via a
    remote desktop...so, tell us about your hardware, please..

    or, maybe you need a new driver for the touchpad/mouse--is your hardware
    certified for Linux? (or have a Penguin on box it came in?)

    again, welcome...

    Thank you all for helping. I've done a mistake and now I'll try to explain better.

    First of all I have KDE4.6.0-OpenSuse 11.4 in an HP notebook with updated BIOS and a NVIDIA GForce 8400m gs with nvidia drivers (installed by the official 11.4 repository). I need that driver because I need 3D accelerated graphics and OpenGL support.

    The problem that I have is not relative to the C-state (as I wrongly said before) of the processor but is relative to the CPU consuming of Xorg. I explain better:

    when I scroll with firefox, okular, thunderbird, libreoffice and other apps, xorg takes 25% of CPU and the fan (unique fan both for CPU than video card) starts to make noise. After the scroll xorg returns to 2% of CPU. This occurs both with touchpad than with usb mouse. My touchpad is the standard HP touchpad.

    Is it normal?
    Can I configure my xorg.conf in an optimal way?

    Thanks a lot

    thanks for the new details...unfortunately, with it i can only say that
    it may or may not be 'normal'..

    i know (from reading around in the forums for three years) that some HP
    notbooks like Linux better than some others...some work perfect with the
    power savings and cpu throttling stuff with ultra quiet fans in openSUSE
    and some don't..

    also, some HPs are old and lots of cat hair and chicken bones floating
    around inside....and, therefore have a heat build up problem and run
    fans like crazy..

    and, some HPs which ran great on 10.3 are noisy on 11.3 (and vice versa)..

    also, some HPs run great (and quite) with openSUSE and not so great with
    Ubuntu/Red Hat/etc (and vice versa)

    and, some HPs run quietly with WinX and not with any Linux--which some
    HPs run silently with some Linux distros and _not_ with WinX

    tell me, is your HP certified for Linux or Windows or both..(they sell
    machines for either, but as far as i know, not for both)

    have you looked on the HP site to see if there is an BIOS update
    available? or any information on using the machine with anything other
    than Windows?

    so, to determine what is normal we need to find some other folks running
    openSUSE 11.4 on the same model number as yours, and learn if yours is
    normal, or not..

    is there an HP forum where you might find a bunch of folks running Linux
    on your model?

    another way to do that is with google, maybe a search string like

    sitepensuse.org "11.4" "HP [model number]" "GForce 8400m" "fan noise"
    OR loud OR "noisy fan"

    if you don't get much from that, drop off the graphics or change up some
    of the other stuff..

    and, maybe drop the site specific and see if there is a generic Linux
    problem with your model, like this

    linux "HP [model number]" "GForce 8400m" "fan noise" OR loud OR "noisy
    fan" OR problem OR trouble


    > Can I configure my xorg.conf in an optimal way?


    if you are lucky you will find someone with your exact model who had the
    same problem AND figured out how to solve it AND wrote that into a post,
    somewhere..

    by the way: do you have an xorg.conf?
