Perfect 7970 scrypt coin setup

This guide is for a 2 card setup but can be modified for 1-7 cards

Install xubuntu 12.0.4 LTS 32bit

Download the 2 files below using a web browser because it requires acceptance of the ATI tearms and conditions. Make sure they’re in ~/Downloads

http://developer.amd.com/amd-license-agreement/?f=ADL_SDK_5.0.zip  

http://developer.amd.com/tools/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/#one 

Install ssh server. This stem is not mandatory but will come in handy if you would like to install via ssh.

sudo apt-get update && sudo apt-get install openssh-server 

sudo reboot

You want to make sure there are no old AMD drivers, With a clean xubuntu install there should be none but run just incase.

sudo sh /usr/share/ati/fglrx-uninstall.sh 

sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* xorg-driver-fglrx

Install pre-requisites for ATI video drivers and cgminer. ( all one line )

sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases i386 libcurl4-openssl-dev libncurses5-dev pkg-config automake yasm

Install the ATI video driver

cd /tmp 

wget  http://www2.ati.com/drivers/linux/amd-driver-installer-catalyst-13-4-linux-x86.x86_64.zip  

unzip amd-driver-installer-catalyst-13-4-linux-x86.x86_64.zip 

chmod +x amd-driver-installer-catalyst-13-4-linux-x86.x86_64.zip 

Open up terminal emulator and run:

sudo sh amd-driver-installer-catalyst-13-4-x86.x86_64.run

Initialize video cards and add setup to X config.

sudo aticonfig --adapter=0,1 --initial 

sudo reboot

Install git and download the lates cgminer version.

sudo apt-get install git 

git clone git://github.com/ckolivas/cgminer.git cgminer

Install AMD APP SDK

mkdir amdapp_2-8 

cd amdapp_2-8 

tar -zxvf ~/Downloads/AMD-APP-SDK-v2.8-lnx32.tgz 

sudo ./Install-AMD-APP.sh 

sudo reboot

Install AMD ADL SDK and add to cgminer.

mkdir ADL_SDK 

cd ADL_SDK 

mv ~/Downloads/ADL_SDK_5.0.zip . 

unzip ADL_SDK_5.0.zip 

cp include/* ../cgminer/ADL_SDK

Install cgminer

cd ../cgminer 

./autogen.sh 

CFLAGS="-O2 -Wall -march=native -I /opt/AMDAPP/include/" LDFLAGS="-L/opt/AMDAPP/lib/x86_64" ./configure --enable-scrypt 

make

Create the cgminer config folder

Open terminal emulator 

cd cgminer 

./cgminer 

press CTL C when it ask you for pool information to stop cgminer

close terminal window open 

Create config file

Double click on the home button on your desktop

Click on view and check "Show Hidden Files"

Double click on the .cgminer folder ( don't confuse with the cgminer folder without the period )

Right click and create a new blank document and name it cgminer.conf

Double click to open cgminer.conf

Copy and paste the content below to your cgminer.conf file

{
"pools" : [
{
"url" : "pool URL",
"user" : "pool username",
"pass" : "pool password"
}
]
,
"intensity" : "13,13",
"vectors" : "1,1",
"worksize" : "256,256",

"scan-time" : "30",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

Save the cgminer.conf file

Set up startup script

Double click on the home folder on the desktop 

Double ckick on the cgminer folder ( not .cgminer ) 

Right click and create  a new file called start.sh 

Right click on the newly created file start.sh and open with leafpad 

Copy and paste the script file, contents below

#!/bin/bash
cd ~/cgminer
export DISPLAY=:0
export GPU_MAX_ALLOC_PRECENT=100
export GPU_USE_SYNC_OBJECTS=0
aticonfig --od-enable
./cgminer

Save file and Open terminal emulator.

cd cgminerchmod +x start.sh./cgminer

with this setup and config you will get around 700k hash per card.
