    Re: Ubuntu 12.04 AMD driver issues

    Have you tried the nomodset option? Would possibly at least get you to a usable screen.

    Boot to menu list, select kernel you want to run on the list and hit 'e';
    Locate the kernel line which ends in 'splash' or 'quiet' or a combination of both;
    Add 'nomodset' at the end of that line (without apostrophes);
    Follow instructions at bottom of page to save changes and continue with normal boot.

    Does that get you to at least a usable screen? If so, great, but that won't stick on reboot. Easy enough to make the change permanent, though.

    I realise this isn't fixing your original problem but might get you a bit closer and to something you can work with.

    The screen not showing up correctly isn't a problem anymore, because I can always uninstall the AMD driver from the console either with the .sh uninstall script or with sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

    I am not sure how to tackle this problem anymore and I really don't want to stick with the standard drivers because of the performance.
    After installing the driver be it via .deb package or .run installer, I tried to check if the graphics card is a hybrid with aticonfig --pxl, but it only shows me the current configuration.

    The standard drivers work without problems, except one:
    I remember that in the Dash Home the scrollbar kind of bounces when you scroll to the very top/bottom, but this effect is gone.

    If you're "stuck" with open-source drivers for a card that new, the best thing you could do would be to run Ubuntu 13.04 with this PPA: https://launchpad.net/~oibaf/+archive/graphics-drivers

    You would also need a 3.11 kernel and turn on radeon dpm for best performance: https://help.ubuntu.com/community/Ra...y.29_and_Later

    I just did a little research on the system specs and it turns out, that the system has hybrid graphics if I understand it right.
    The graphics card is an AMD Radeon HD 7670M as mentioned already and the processor is an Intel® Core™ i7-3630QM Processor with something integrated called Intel® HD Graphics 4000.
    Can someone confirm this, please?

    Since this seems to be a hybrid graphics problem, is there absolutely no way to use the AMD driver for this without any further graphic errors?

    That's odd. Why didn't lspci show the Intel GPU?

    Re: Ubuntu 12.04 AMD driver issues

    This is just a chance, but since there are two graphics cards wouldn't it be possible to disable the Intel one from the BIOS and use the AMD with Fglrx or disable AMD Radeon & use only Intel GPU which is likely to have better performance with open source drivers?

    I really don't know.
    The command:
    Code:
    aticonfig --pxl
    resulted in:
    Code:
    PowerXpress: Discrete GPU is active (High-Performance mode).
    I never saw any trace of the Intel GPU, maybe that's because according to Intel not every system is capable of additional functionality including hybrid graphics:
    ‡ This feature may not be available on all computing systems.
    Excerpt from Intel at the bottom.
    The row Processor Graphics is marked with this symbol: ‡

    @bhattabhishek

    Well, maybe it's possible.
    But for that it should be determined if the system really has hybrid graphics or not.

    codingaround, i feel for you, its really frustrating not to get the graphics driver working...
    What is the make and model of your laptop?


    Have you searched Gentoo & Arch forums ?

    Maybe you will find a missing link there, might just try.

    The laptop is a Toshiba Satellite L870-177 and yes, I did search the Gentoo & Arch forums.
    There wasn't any new information that could help and most solutions applied to the Gentoo and Arch Linux distributions.
