    Re: overheating in ubuntu 12.04

    strange lvds_downlock did not improve battery life

    I guess i would delete it

    Code:
    sudo rm /etc/modprobe.d/i915.conf
    i going to add it to grub default

    follow the guide to permentely add it on the bottom of the page
    https://wiki.ubuntu.com/Kernel/KernelBootParameters

    i want you to add these two between the quotes
    Code:
    i915.i915_enable_fbc=1   i915.lvds_downclock=1
    so it should look something like this

    GRUB_CMDLINE_LINUX="quiet splash i915.i915_enable_fbc=1 i915.lvds_downclock=1"

    then
    Code:
    sudo update-grub
    (\ /)
    (O.o)

    Re: overheating in ubuntu 12.04

    i added these variables through the temporary method but still, i want to share the result of sensors cmd
    ~$ sensors
    acpitz-virtual-0
    Adapter: Virtual device
    temp1: +71.0°C (crit = +120.0°C)

    coretemp-isa-0000
    Adapter: ISA adapter
    Physical id 0: +71.0°C (high = +80.0°C, crit = +85.0°C)
    Core 0: +71.0°C (high = +80.0°C, crit = +85.0°C)
    Core 1: +70.0°C (high = +80.0°C, crit = +85.0°C)

    and this is when just have opened firefox and terminal.
    Shall i add these through permanent method and then test it for 2-3 days?

    Mr. "pscool" my laptop's [it is new Dell Vostro 3550, with Core i5-2nd generation cpu, and with hybrid (capable of automatically switch according to needs) graphics {Intel HD3000 (inbuilt into cpu) + AMD Radeon 6600/6700 series}] overheating problem gone after installing appropriate graphics driver. Now my system (with Ubuntu 12.04) is running cooler like Windows 7. Though my system is different than your system, I think the solution method will also be applicable for your system. Because I use the same method for my different systems.
    Method: It is automated driver installation procedure using "Additional Drivers".
    If you unable to understand the method, then I can explain it to you.

    First try the easy method described below:

    Let your Intel graphics (HD 3000) driver installation process hand over to built-in "Additional Drivers".

    1.
    You need an active Internet connection.

    2.
    Update your system first. To do this, run following 2 commands in terminal one by one (each one will take time, so keep patience):

    sudo apt-get update
    sudo apt-get upgrade

    3.
    Restart your system.

    4.
    Save a backup copy of xorg.conf in case this process doesn't work (to avoid reinstallation of ubuntu).

    sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

    5.
    Now search for "Additional Drivers" in the Ubuntu Dash Home (Unity).
    Or click on wheel button located on top right hand corner of desktop "System Settings" => "Hardware" => "Additional Drivers".
    The software named "Additional Drivers" will search for available drivers. A window will show you up the available drivers available for your system.
    Select "your graphics driver".
    Now click on "Activate".
    After downloading it will install appropriate driver for your graphics system automatically.

    6.
    Restart your system.

    7.
    Now open "your installed driver software interface (after searching in unity dash home)". It may show you some error message, with valuable instructions to fix this problem. Follow the instructions using terminal.

    sudo <instructed command>

    8.
    Restart your system again.

    9.
    Search for "your graphics driver software interface" in Ubuntu unity dash home.

    10.
    Now it will open successfully (if you followed the instructions correctly). You will be able to change the default settings of your graphics card (if you open it using sudo or in administrative mode).

    11.
    You will see that the excess heating problem gone, battery life increased, watch the processor fan speed.

    Please post error messages (with screen-shoot), if you get in the above process. It will show exact problem which you are facing, and will help to diagnose the problem.

    PS: I'm very busy, so please wait for my reply.
