    Lightbulb AMD/Intel Hybrid Graphics works

    If you do want to make the switch possible between your Intel and your AMD graphics cards, then this post is for you. If you do not own a AMD hybrid graphic card, please leave this thread, and post your problems in a thread made for AMD single graphic or Intel single graphic.

    Edit: The solution seems not to work with ATI 5xxx graphic cards, try at your own risk.
    Warning: Works only for muxless systems.
    Warning 2: Check if your BIOS is updated, if not update it ! (You will need Windows). This is your computer manufacturer that "implements the switch on your mother card, and modify the video drivers for Windows to work on your computer". If an AMD 6630m (for example) works on a HP computer, this doesn't mean the same video card will work for sure (for example) on a ASUS computer.

    Edit bodhi.zazen: Best check hardware compatibility before following this tutorial. If your hardware is not listed as supported, this tutorial will not help you. See http://wiki.cchtml.com/index.php/Hardware

    The following solution has been tested on a DELL Vostro 3550, with an AMD 6630m card and an Intel HD 3000 (Sandybridge) card (integrated into a Intel core i5). The version of Ubuntu used is 12.04 LTS (further versions should works too). The system is very stable, and everything works well.
    This tutorial requires the use of the terminal, but still is simple if you're a beginner, you will just have to past some commands on it and press "Enter".
    (Tip for beginners : to past a command on a terminal, just press CTRL+SHIFT+V, it is the same shorcut as usual just don't forget to press SHIFT when pasting).

    Before beginning this tutorial, we will suppose you are following it on a fresh install (i.e. You did not install vgaswitchroo or flgrx (via jockey-gtk : The proprietary driver installer application from Ubuntu). Please also install all updates available for your computer before starting (and reboot if you're proposed to).

    STEP 1 - Installing latest AMD catalyst drivers :


    As I'm writing this the latest version is 12.4, please check this page to know if there is a new version :
    http://wiki.cchtml.com/index.php/Ubu...allation_Guide (this also includes the guide to install them).

    First we're going to download all the prerequisite packages :
    Code:
    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 Ubuntu 64bits please run those two commands (32bits users don't have to) :
    Code:
    sudo apt-get install ia32-libs lib32gcc1 libc6-i386
    cd /usr ; sudo ln -svT lib /usr/lib64
    We can now download the AMD catalyst 12.4 driver :
    Code:
    cd ~/; mkdir catalyst12.4; cd catalyst12.4/
    wget http://www2.ati.com/drivers/linux/amd-driver-installer-12-4-x86.x86_64.run
    chmod +x amd-driver-installer-12-4-x86.x86_64.run
    And create Ubuntu packages of it :

    Code:
    sudo sh ./amd-driver-installer-12-4-x86.x86_64.run --buildpkg Ubuntu/precise
    Now let's install them :
    Code:
    sudo dpkg -i fglrx*.deb
    and configure the Xserver (xorg.conf file) for the first time :
    Code:
    sudo aticonfig --initial -f
    Now reboot your computer.

    Test the switch to the discrete card :
    Code:
    sudo aticonfig --px-dgpu
    Then reboot again your computer.

    STEP 2 - Enabling, fixing the bug for direct rendering on the integrated card :

    Thanks to Niccola for finding the actual fix.


    If you ever apply an fglrx update, or your system automatically update fglrx, YOU WILL HAVE to repeat STEP 2, otherwise direct rendering will be missing on integrated gpu (i.e. No Unity 3D or Gnome Shell or Gnome Classic + Compiz on the Intel graphic). If you have an other solution (like loading a script on startup) please post it.

    Open the /etc/X11/Xsession.d/10fglrx file with root rights :
    Code:
    gksu gedit /etc/X11/Xsession.d/10fglrx
    If you're using a 32bits system add at the end of 4th line this text : "/usr/lib32/dri/" without the quotes. The file should now look like this :
    Code:
     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=${LD_LIBRARY_PATH}/usr/lib32 
    export LD_LIBRARY_PATH 
    fi 
    fi 
    export LIBGL_DRIVERS_PATH
    If you're using a 64bits system add at the end of 4th line this text : "/usr/lib/x86_64-linux-gnu/dri/" without the quotes. The file should now look like this :
    Code:
     LIBGL_DRIVERS_PATH=/usr/lib/fglrx/dri 
    if [ `uname -m` = 'x86_64' ]; then 
    if [ -d /usr/lib32/fglrx/dri ]; then 
    LIBGL_DRIVERS_PATH=${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
    Now save the file.

    STEP 3 - Enjoy your hybrid graphic system ! :

    Reboot your computer to see the changes, it should boot up with the discrete card.

    Useful informations, commands :

    Power consumption is a lot better now, it seems that my battery last 4 times more with the integrated card, but this isn't still good as in Windows. If someone find or know tricks to decrease power consumption a little more please post it !

    I do not recommend to update the catalyst driver once it's installed (if it works), if you really want to upgrade then check this page to find instructions :
    http://wiki.cchtml.com/index.php/Ubuntu

    The AMD driver GUI application doesn't provide settings for screen configuration, but only 3d settings. This is a missing feature.

    Switching commands :
    Code:
    aticonfig --pxl # List current activated GPU
    sudo aticonfig --px-dgpu # Activate discrete GPU (High-Performance mode), must re-start X to take effect
    sudo aticonfig --px-igpu # Activate integrated GPU (Power-Saving mode), must re-start X to take effect
    Verify the Open GL's libraries used :
    Code:
    fglrxinfo
    Verify if the direct rendering is used :
    Code:
    glxinfo | egrep render
    Install mesa-utils, and test the card 3d power (compare the fps) :
    Code:
    sudo apt-get install mesa-utils
    glxgears
    If something goes wrong and your computer doesn't boot (i.e. black screen), press CTRL+ALT+F3, log yourself into your account and enter those commands :
    Code:
    sudo rm /etc/X11/xorg.conf
    sudo startx
    And you should be able to see your desktop.

    If you want to add your computer, please do want it (this will help other users), make a post and indicate your configuration like those above.
    I will then add it to the working list.
    I repeat as many people do not get it : "like those above" ! It take you two minutes to write it, this saves me time, and I can update more frequently this thread. Also posts like "It works on HP Pavilion dm4" are USELESS, I won't add a computer with an incomplete computer model number. Exception for computers without a precise model name (example : DELL Vostro 3550, Lenovo e520).



    Useful links :
    http://forums.gentoo.org/viewtopic-p-6936730.html You can thanks that guy because his post really helped me to understand how the ati hybrid graphics works.
    http://en.gentoo-wiki.com/wiki/Fglrx-hybrid-graphics You can also check this Gentoo wiki about hybrid graphics, this is some Gentoo's users that actually found first a solution on how to make AMD hybrid cards to work on Linux.
