oclHashcat-plus + Ubuntu Desktop 12.04 + AMD Radeon 7600M

[redf00t]

Okay - I got it working!!!!

It's a bit of a fudge and I dont know what the performance will be like but I have the following working.

Dell Vostro 3650 with AMD Radeon HD 7600M Series in Hybrid mode (Intel VGA driver running ubuntu and AMD Catalyst for Hashcat)

Here's how i did it.

Fresh 12.04.1 LTS x86_64 install

update

Code:

sudo apt-get update ; sudo apt-get upgrade -y

install some other bits and bobs for building the package and some 32 bit libs:

Code:

sudo apt-get install ia32-libs lib32gcc1 libc6-i386 build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases linux-headers-generic xserver-xorg-core libgcc1

link 32 bit libs to 64 bit libs

Code:

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

Get the ati catalyst driver

Code:

wget http://www2.ati.com/drivers/linux/amd-driver-installer-catalyst-13.1-linux-x86.x86_64.zip

Build a dpkg rather than running the install script:

Code:

sudo sh ./amd-driver-installer-catalyst-13.1-linux-x86.x86_64.run --buildpkg Ubuntu/precise

install your debs:

Code:

sudo dpkg -i fglrx*.deb

Build a new xorg.conf file

Code:

sudo aticonfig --initial -f

OPTIONAL - enable dual monitors

Code:

sudo aticonfig --set-pcs-str="DDX,EnableRandR12,FALSE"

discrete GPU mode (important for me as i wanted intel to run ubuntu)

Code:

sudo aticonfig --px-dgpu

reboot

Code:

sudo reboot

Fingers crossed you dont get the dreaded "running in low graphics mode"

Test your setup:

crack a cheap wpa psk, just cause you can ;-)

Thanks to dioxide for putting me in the right path to begin with, it seems it was an xorg.conf issue and looking back at the xorg logs, a libs issue too!

Thanks to HashCat also, long live the good work of @atom and co.

Hope this helps someone else with a Radeon card, its so much simpler with nvidia.

PS - can an admin mark this as solved, if they are happy with the fix/fudge?
