    Ubuntu video on HP Pavilion g7 1153er with hybrid radeon 6470M and Intel 3000

    Hello everybody. I will start this thread like most of people.
    I am new guy in Ubuntu. I have tried to make right installation but always getting some problems. I have laptop HP Pavilion g7 1153er.
    This laptop equipped with ATI Radeon HD 6470M and i5 2410M CPU so I have hybrid graphic with Intel hd video 3000. I have took this laptop with Windows.

    But I am working with web-services and developement a lot so would like change my OS to Ubuntu. I have started with Ubuntu 12.04 and got that my system doesnt want to start up without additional parameter nomodeset. I have used it, install OS and thought that problem is with radeon. So I have installed (from 7 time reinstalled OS) driver from amd site. But this isn't help. When I checked my logs I see that main problem is with intel video.
    Fatal server error:
    [    18.145] atiddxProbe: fail to probe intel VGA device
    [    18.145] (EE) 
    Please consult the The X.Org Foundation support 
     for help. 
    [    18.145] (EE) Please also check the log file at "/var/log/Xorg.0.log" for additional information.
    [    18.146] (EE)
    I checked intel drivers and saw that they are adapted to Ubuntu 13.04 now. So I have tried few times install them to Ubuntu 12.04 and failed. To move further I have installed Ubuntu 13.04. This system required two additional boot parameters to work: acpi=off and nomodeset. I have installed and seen that it works with slow screen processing. Than I installed Intel driver and this helped to me remove acpi=off from boot string.

    I have digged a lot of info to check all this things like a new user. I know that experience it is great but I am trying to solve this problem third day and my work is stopped. Do not want to switch back

    So could any body help me to find solution for video processing speed. I still thinking that problem is with drivers.
    What is the best in my situation? And do I need to use nomodest for each start up?

    Please help me with this problem or post some links for similar problem. I have checked many posts but problems was little bit different.

    Sorry for my english and thanks

    Maybe this will help.

    If you don't care about switching between the Intel and ATI graphics chips, go into the BIOS and turn on "fixed mode." That will force the machine to use the ATI chip all the time. Now run the "Additional Drivers" application to make sure it has installed the ATI driver. I'm using an HP dv6t here with the ATI device forced on and an HDMI connection to a television.
    If you ask for help, please have the courtesy to check for responses and thank the people who helped you.

    Thanks for reply.

    I have posted one forum ( and I have got reply with suggestion to try "acpi_backlight=vendor" option for grub. This helped a lot. With using acpi_backlight=vendor option without nomodest I have seen right graphics for ubuntu 12.04 but havent set hybrid graphics there right.

    Than I have tried to do the same with Ubuntu 13.04. And made:
    1) “acpi_backlight=vendor” option in start line for installation Ubuntu 13.04
    2) after installing OS all grub options left configurated in grub. So I have installed intel driver than(
    3) checked grub configuration,
     $ sudo gedit /etc/default/grub
    keeped “acpi_backlight=vendor”, and removed “nomodeset” from there and got GRUB_CMDLINE_LINUX="acpi_backlight=vendor"
    saved config
    $ sudo update-grub
    4) installed ati catalyst according to

    And after this steps I have got all my problems solved

    The main reason of atiddxProbe: fail to probe intel VGA device was using of “nomodeset” at grub for boot without black screen but “acpi_backlight=vendor” helped a lot.
