==Disclaimer==
The below guide is for personal reference. If anyone other than the author uses it, it is at their own risk. Nothing in here describes anything about security, so that's up to you to figure out and prevent all your virtual currency from being stolen. 
 
You've been warned 
 
==Install OS and software==
If this is a dedicated mining box, install Ubuntu Server 12.04 LTS (latest LTS version at the time of this writing, supported until 04/2017) 
http://releases.ubuntu.com/precise/ubuntu-12.04.3-server-amd64.iso
Install ssh during the Operating system install 
 
update and upgrade all packages on your system
sudo apt-get update && apt-get upgrade
install needed tools
sudo apt-get install -y build-essential gcc make cmake mc python-dev subversion git bzip2 unzip xorg
xorg needs to be installed before the amd packages are downloaded and installed otherwise you will get errors citing that apt-get cannot create symlinks to files that dont exist
 
install the AMD/ATI drivers and software
sudo apt-get install fglrx-updates fglrx-amdcccle-updates fglrx-updates-dev
==Begin Configuration==
configure xorg for the video cards
sudo aticonfig --lsa
sudo aticonfig --adapter=all --initial
reboot for settings to apply
sudo reboot
 
===xinit script===
On the server edition if you try to run<code>sudo aticonfig --adapter=all --odgt</code> at this point, you'll get an error:
ERROR - X needs to be running to perform AMD Overdrive(TM) commands
To correct this, we need to create a startup script to get X initialized. I did the following: 
:1. create a file in my mining folder and paste the script
nano /etc/mining/xinit

#!/bin/bash
# standard functions library
. /lib/lsb/init-functions
# Start the xinit
start() {
# Start xinit on background and redirect stdout and stderr to log file
echo "Starting xinit"
xinit &> /var/log/xinit.log &
}
# Restart the xinit
stop() {
echo "Stopping xinit"
killall xinit
}
### main logic ###
case "$1" in
start)
start
;;
stop)
stop
;;
status)
status xinit
;;
restart|reload|condrestart)
stop
start
;;
*)
echo $"Usage: $0 {start|stop|restart|reload|status}"
exit 1
esac
exit 0
:2. with the script created, next is to set executable permissions and add it to init.d for easy auto start and managing
sudo chmod +x /etc/mining/xinit
sudo ls -s /etc/mining/xinit /etc/init.d/xinit
sudo /etc/init.d/xinit start
:While the above works, I have '''not''' found it to be 100% reliable. Sometimes I will still get the error about X not running, so I added a line to launch it during the litecoin mining script we'll create later. 
:3. run a couple more config settings which will also be present in the litecoin mining script we'll create later
export DISPLAY=:0
echo export DISPLAY=:0 >> ~/.bashrc
:4. test to see if aticonfig now shows card results without complaining about X not running
r00t@miner1:/etc/mining$ sudo aticonfig --adapter=all --odgt
[sudo] password for r00t:

Adapter 0 - AMD Radeon HD 6800 Series
Sensor 0: Temperature - 89.00 C

Adapter 1 - AMD Radeon HD 6800 Series
Sensor 0: Temperature - 73.00 C

==CGMiner download and config==
Before I could run cgminer, I was getting errors that I had to fix:
./cgminer: error while loading shared libraries: libudev.so.1: cannot open shared object file: No such file or directory
Added the following symlinks to fix it:
sudo ln -s /usr/local/lib/libjansson.so.4 /usr/lib/libjansson.so.4
sudo ln -s /lib/x86_64-linux-gnu/libudev.so.0 /lib/x86_64-linux-gnu/libudev.so.1
Download cgminer 3.7.2 and unzip (last version that has GPU support since the author says GPU mining is dead due to ASIC miners and such)
wget http://ck.kolivas.org/apps/cgminer/3.7/cgminer-3.7.2-x86_64-built.tar.bz2
tar jxvf cgminer-3.7.2-x86_64-built.tar.bz2
Check to see if cgminer can see your video cards, should be an output like such
r00t@miner1:/etc/mining$ cd cgminer-3.7.2-x86_64-built
r00t@miner1:/etc/mining/cgminer-3.7.2-x86_64-built$ ./cgminer -n

==Create a litecoin mining script==
Now we create the litecoin mining script that I mentioned earlier. This section will probably change as right now I have it relying on sudo to start, which I dont want and would rather it start automatically with the system boot. However, it's functional. 
In your CGMiner directory, create a script. Keep in mind, my script is for Dual (2) 6870s, you may need to adjust your cgminer settings to get the best results. In this, you see that I call upon the xinit script we created earlier, this is because I've launched the xinit script 10 minutes prior to mining and had issues because it had stopped running by then. Figured I'd just add this to make sure it's running before I start mining.
nano mine_litecoins.sh

#!/bin/sh
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
/etc/init.d/xinit start
cd /etc/mining/cgminer-3.7.2-x86_64-built
#./cgminer --scrypt -I 18,18 -w 64,64 --thread-concurrency 6720,6720 --gpu-engine 900 --gpu-memclock 1050 --auto-fan --temp-target 60 -o stratum+tcp://america.mine-litecoin.com -u [username] -p [password]

./cgminer --scrypt -I 18,18 -w 64,64 --thread-concurrency 6720,6720 --gpu-engine 900 --gpu-memclock 1050 --auto-fan --temp-target 60 -o stratum+tcp://usa-1.liteguardian.com:3334 -u [username] -p [password] --failover-only -o stratum+tcp://eu-1.liteguardian.com:3334 -u [username] -p [password]
Make the script executable
sudo chmod +x mine_litecoins.sh

==Mine Coins!==
Here's the moment of truth:
sudo /etc/mining/cgminer-3.7.2-x86_64-built/mine_litecoins.sh
You should be presented with a screen that looks like this:

I'll be updating this with more information in the future, like how to autostart everything upon system boot, how to ssh in and check to see how its doing, etc. All that information is already out there, but I haven't done it yet so I know nothing about it.
