I am using 12.04 LTS version of ubuntu. In which I am getting High CPU temperature and fan speed from beginning of the system. Temperature remain > 62°C. I am using jupitar but it's not helping in case of mine. Jupitar in power saving mode. And very low battery backup. Help me with this problem.

I am using hp pavilion dv6 - 6120tx Processor Intel Core i5-2410M GPU Model AMD Radeon HD 6490M

Apparently you didn't install drivers for your dGPU (your Radeon), here is what you have to do:

  • You have to download the following packages:

sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6

sudo apt-get install dkms libqtgui4 wget execstack libelfg0 dh-modaliases

sudo apt-get install linux-headers-generic xserver-xorg-core libgcc1

  • If you're using a 64bit system, addditionally install these packages as well

sudo apt-get install ia32-libs lib32gcc1 libc6-i386

cd /usr ; sudo ln -svT lib /usr/lib64

  • Download and install drivers

cd ~/; mkdir catalyst12.10; cd catalyst12.10/

wget http://www2.ati.com/drivers/linux/amd-driver-installer-catalyst-12.10-x86.x86_64.zip

chmod +x amd-driver-installer-12-10-x86.x86_64.run

sudo sh ./amd-driver-installer-12-4-x86.x86_64.run --buildpkg Ubuntu/precise

sudo dpkg -i fglrx*.deb

sudo aticonfig --initial -f

  • Reboot

If you are having problems with switching to your iGPU and Unity3D, you may have to change the /etc/X11/Xsession.d/10fglrx with root

gksu gedit /etc/X11/Xsession.d/10fglrx

If you are using a 32 bit system, the file has to look like this:

LIBGL_DRIVERS_PATH=/usr/lib/fglrx/dri if [uname -m= 'x86_64' ]; then if [ -d /usr/lib32/fglrx/dri ]; then LIBGL_DRIVERS_PATH=${LIBGL_DRIVERS_PATH}:/usr/lib32/fglrx/dri:/usr/lib32/dri if [ ! -z $LD_LIBRARY_PATH ]; then LD_LIBRARY_PATH=$LD_LIBRARY_PATH: fi LD_LIBRARY_PATH=${LD_LIBRARY_PATH}/usr/lib32 export LD_LIBRARY_PATH fi fi export LIBGL_DRIVERS_PATH

If you are using a 64bit system, like this:

LIBGL_DRIVERS_PATH=/usr/lib/fglrx/dri if [uname -m= 'x86_64' ]; then if [ -d /usr/lib32/fglrx/dri ]; then LIBGL_DRIVERS_PATH=${LIBGL_DRIVERS_PATH}:/usr/lib32/fglrx/dri:/usr/lib/x86_64-linux-gnu/dri if [ ! -z $LD_LIBRARY_PATH ]; then LD_LIBRARY_PATH=$LD_LIBRARY_PATH: fi LD_LIBRARY_PATH=${LD_LIBRARY_PATH}/usr/lib32 export LD_LIBRARY_PATH fi fi export LIBGL_DRIVERS_PATH
