Thread: prepare_preload XOrg CPU Usage after Flash play

  1. #1

    Default prepare_preload XOrg CPU Usage after Flash play

    Hi,

    Usually after I played several flash movies in Opera and FireFox, the CPU usage goes crazy. Once it happens, if I reboot the system, usually prepare_preload keeps using a lot of CPU Usage. And then later, XOrg does that.

    Sometimes the system monitor shows low CPU usage, but the system is a lot less responsive and the CPU usage spikes if I do anything.

    Only after some time/several reboot the system goes to normal.

    I'm using openSUSE 11.2 x64 with Dell E6400/8GB Ram/Intel Graphics Card.

    Any help will be much appreciated!

    Thank you,
    Joon

    Which Intel GPU?
    Is this on GNOME or KDE4?
    Do you use an xorg.conf ?
    Has this been like this since you installed?
    Did you ever perform a memory test?

    If you boot the system from a liveCD do you have the same issues?

    Which Intel GPU?
    -> Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz

    Is this on GNOME or KDE4?
    Gnome 2.28.2

    Do you use an xorg.conf ?

    -> I don't think so. I don't have /etc/X11/xorg.conf

    Has this been like this since you installed?
    -> I have installed openSUSE three times (without changing home folder) and
    it has been like that. Thuogh it seemd the second installation, I messed up
    my wireless driver a little bit (I have broadcom) and it seemed worse at that
    time.

    Did you ever perform a memory test?

    -> I don't know how to do this.

    If you boot the system from a liveCD do you have the same issues?

    -> Have not tried it. In fact I have never used liveCD.

    Thank you!

    There is a memory test option on the install media menu.

    I think I might have found the source of the CPU usage problem. It seems when I do some heavy computation with Python or play HD movies, the CPU clock strangely becomes stuck at 800MHz.

    Code:
    joon@linux-i9f6:~> cpufreq-info
    cpufrequtils 005: cpufreq-info (C) Dominik Brodowski 2004-2006
    Report errors and bugs to http://bugs.opensuse.org, please.
    analyzing CPU 0:
      driver: acpi-cpufreq
      CPUs which need to switch frequency at the same time: 0
      hardware limits: 800 MHz - 2.27 GHz
      available frequency steps: 2.27 GHz, 2.27 GHz, 1.60 GHz, 800 MHz
      available cpufreq governors: conservative, userspace, powersave, ondemand, performance
      current policy: frequency should be within 800 MHz and 800 MHz.
                      The governor "ondemand" may decide which speed to use
                      within this range.
      current CPU frequency is 800 MHz.
    analyzing CPU 1:
      driver: acpi-cpufreq
      CPUs which need to switch frequency at the same time: 1
      hardware limits: 800 MHz - 2.27 GHz
      available frequency steps: 2.27 GHz, 2.27 GHz, 1.60 GHz, 800 MHz
      available cpufreq governors: conservative, userspace, powersave, ondemand, performance
      current policy: frequency should be within 800 MHz and 800 MHz.
                      The governor "ondemand" may decide which speed to use
                      within this range.
      current CPU frequency is 800 MHz.
    In the normal situation,
    Code:
    frequency should be within 800 MHz and 800 MHz
    part is
    Code:
    frequency should be within 800 MHz and 2.27 GHz.
    .
    So because of the frequency stepdown my computer became very sluggish.

    I just found out about this so I haven't had chance to try
    Code:
    sudo cpufreq-set -c 0 -u 2.27GHz
    , and I'm not sure if it will work.

    Any help will be greatly appreciated.

    Thank you,
    Joon

    You should be able to set policy in Yast

    I'm sorry, but may I ask you which menu in YaST?

    Hmm possibly it is no longer in the default install. In Yast-Software Management search for yast2-power. Install that mod and you should be able to control policy.

    If ur on KDE , you could access power options on system preferences, then, advanced tab.

    I have installed it and I'm seeing power management now, but I'm seeing only four choices and it is set to default.

    I think it is a bug related problem, because in the cases where the CPU freq stuck to 800MHz, I did not touch anything.

    I will check what I can do with this power management next time it happens.

    Thanks!
    Joon.

    ps. I'm using GNOME
