    Hooray !!

    Your hybrid graphics card configured correctly.. everything seems to work as it should.

    As for the fan.. watch it 1-2 days and if still make a lot of noise come back , I will give you something to add , for extra power-saving with the intel card. (this card you will use mostly).

    And for your temperatures , do not bother for 2-3-4 degrees.. My temperatures are 50 to 60 . Do not forget it is a Laptop. Very good temperatures.
    Thanks

    Hi again

    She keeps complaining. It goes like 10 seconds per minute. It vibrates and makes a noticeable (not too loud) noise.

    Also, using kile I hear a low sound (like a fast clock ticking) every time I press a key Is that normal?


    Thanks!

    Give the results of
    Code:
    cat /etc/default/grub
    and we will try an option for the Intel card that sets the card in a low power state when its idle.

    Cannot go further , I don't know something else except this parameter.
    Maybe you should look the hardware .

    Re: Power managment -- fan noise Asus U31

    First give this command (copy-paste from here)

    Code:
    sudo sed 's/GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"/GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.i915_enable_rc6=1"/' -i /etc/default/grub
    To check the change give this command
    Code:
    cat /etc/default/grub | grep GRUB_CMDLINE
    The result must be
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.i915_enable_rc6=1"
    GRUB_CMDLINE_LINUX=""
    Then run
    Code:
    sudo update-grub
    and reboot.

    Re: Power managment -- fan noise Asus U31

    OK

    I did it, the result afterwards was the same as yours.

    BTW, what does this command mean? What changed?

    code:
    Code:
    sudo sed 's/GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"/GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.i915_enable_rc6=1"/' -i /etc/default/grub



    However, at least at the moment I find everything unchanged...

    Thank you anyway!!! You're great!

    Cannot do anything else. If this is a hardware problem (fan) you should check it.

    The command changes this line
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    to this
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.i915_enable_rc6=1"
    This is the parameter I told you about the power-save with Intel card. We enabled this through the boot-loader (grub) in the kernel. By default is disabled.

    Re: Power managment -- fan noise Asus U31

    Hi my friend,

    Do you know how to truly set the screen brightness for once and for ever?

    It changes wildly, it increases a lot. I can't seem to find the proper commands, I found this to set the brightness down:
    Code:
    echo 300 > /sys/class/backlight/intel_backlight/brightness
    but after a while it increases again...

    The keys Fn+F5 and Fn+F6 work fine, but the lowest they can get is still too bright, that's why I'm using the backlight command on the terminal.

    Any hints?
    Thanks
