    Unhappy MSI GX623 runs hot/battery time affected

    Hi guys, so

    1. i am dualbooting latest ubuntu (10.04 beta1 fully updated) via wubi
    2. main operating system is win7 (everything runs completely fine)
    3. battery time on windows = 2h 30min, linux = 1h 20min

    to get to my problem

    1. i tried 9.10,10.04 on both ubuntu version "everything" runs pretty solid except laptop fan runs much faster and laptop is noticeable hotter
    2. CPU scaling works just fine
    3. i tried AMD ATI drivers on 9.10 (i had video playback problems and i had some bad delay maximizing windows, etc) laptop was still running hot
    4. i am running "default" ATI drivers on my 10.04 (video playback works perfectly, even compiz effects could be enabled (awesome) but still laptop runs very hot

    laptop is using ATI Mobility Radeon HD 4670

    could anyone share any ideas how i could solve this?

    my best guess is that there is some power-saving problem with gpu drivers (gpu is probably running on 3D clocks in performance mode) and its not down-clocking properly to 2D mode,

    i am and advanced windows user but i have only "basic" knowledge of linux systems, so if anyone could share some light how to debug and fix this overheating problem ill be really glad (i want to use ubuntu as main OS on my laptop, but this battery problem and "warm" case of my laptop is preventing me from using it)

    thx for any ideas

    Re: MSI GX623 runs hot/battery time affected

    If you run the open drivers, there's a dynamic clock setting that you can turn on.
    You can set it in /etc/X11/xorg.conf

    Section "Device"
    Identifier "Configured Video Device"
    Driver "ati"
    Option "DynamicClocks" "on"
    Option "mtrr" "on"
    Option "DesktopSetup" "Single"
    Option "ScreenOverlap" "0"
    Option "VideoOverlay" "on"
    Option "OpenGLOverlay" "off"
    Option "Stereo" "off"
    Option "StereoSyncEnable" "1"
    Option "FSAAEnable" "no"
    Option "FSAAScale" "1"
    Option "FSAADisableGamma" "no"
    Option "FSAACustomizeMSPos" "no"
    Option "UseFastTLS" "0"
    Option "BlockSignalsOnLock" "on"
    Option "XAANoOffscreenPixmaps"
    Option "AccelMethod" "XAA"
    EndSection

    --------------------

    You can also adjust the GPU and video RAM clock speeds:

    sudo apt-get install rovclock
    man rovclock

    If you have an intel processor, you can run powertop to recover a few more watts:

    sudo apt-get install powertop
    man powertop

    Re: MSI GX623 runs hot/battery time affected

    i have installed powertop, i also typed sudo gedit /etc/X11/xorg.conf
    in terminal, but only empty file popped out, does it mean something is wrong?

    rovclock isn't working properly (i think)
    sudo rovclock -i

    rovclock may not work for your card. Karmic eliminated xorg.conf, so you have to create one from scratch. Search the forums for the command to give you a default template.

    Here's my rov: (ibm thinkpad t43p with ati firegl)

    Video BIOS shadow found @ 0xc0000
    Reference clock from BIOS: 27.0 MHz

    Core: 398.25 MHz, Mem: 249.75 MHz

    I can declock down to 125 MHz for each and save ~5 watts (from 21 watts to 15 watts).

    According to:

    man xorg

    -config file
    Read the server configuration from file. This option will work
    for any file when the server is run as root (i.e, with real-uid
    0), or for files relative to a directory in the config search
    path for all other users.

    If you give the -config switch without a valid xorg.conf file, it probably will freeze.

    Post the output of your xorg.conf.

    Why is gdm disabled? That can create problems with logging out and logging in, since many session attributes are controlled by gdm.

    i said -configure not config , if i am correct Xorg -configure should generate a new xorg.conf, however it always freeze, so all i have its an empty xorg.conf

    Re: MSI GX623 runs hot/battery time affected

    Yes, my mistake. -configure should create a valid xorg.conf file. But the man page also says that it doesn't work on some systems.

    Boot to a rescue shell (from the grub menu).

    cd /etc/X11
    ls
    (probably no xorg.conf file to be found)
    xorg -configure
    ls
    (hopefully you will have an xorg.conf file)
