#### I did not have luck letting GDM auto-login work, so I recommend removing GDM and using a script to startx, you can try it without this option if you want
$ update-rc.d -f gdm remove
$ sudo apt-get purge gdm
$ sudo dpkg --purge gdm 
$ sudo nano /etc/rc.local
#add this line just before exit 0:  su - user -c startx &
control o enter
control x
$ sudo sync
$ sudo coldreboot
#### end remove gdm auto-login to replace with startx

#### download and install driver
$ cd /home/user/Downloads
$ wget http://www2.ati.com/DRIVERS/hotfix/radeon_7900_series/amd-driver-installer-8.921-x86.x86_64.run
$ sudo chmod +x amd*

#### this next step should be run from VNC or directly on the machine instructions for vnc setup here, but you can skip if doing locally
$ sudo chmod uog+rw /dev/ati/card* 
$ sudo xauth merge /home/user/.Xauthority 
$ export DISPLAY=:0
#### And now your ready to connect using X11 forwarding.
#### Windows users can select X11 forwarding in putty by ticking the box located on the menu sidebar/Connections/SSH/X11.
#### end VNC setup

$ sudo ./amd* --force
#### GUI installation will eventually open select all the default options to install 
1) Install driver 8.921 - continue
2) !Agree
3) Automatic
4) Exit
#### GUI complete
 
$ sudo aticonfig --adapter=ALL -f --initial
$ sudo sync
$ sudo coldreboot

$ sudo su
# cd /opt
# wget http://developer.amd.com/Downloads/AMD-APP-SDK-v2.6-lnx64.tgz
# tar -xvzf /home/ubuntu/AMD-APP-SDK-v2.6-lnx64.tgz
# cd AMD-APP-SDK-v2.6-lnx64/
# cp -pv lib/x86_64/* /usr/lib/
# rsync -avl include/CL/ /usr/include/CL/
# tar -xvzf icd-registration.tgz
# rsync -avl etc/OpenCL/ /etc/OpenCL/
# ldconfig
# sync
# coldreboot

#### other configurations
add this line to rc.local : /usr/local/bin/miner-launcher.sh 60 &
#### nano /usr/local/bin miner-launcher.sh
#!/bin/bash
DEFAULT_DELAY=0

if [ "x$1" = "x" -o "x$1" = "xnone" ]; then
   DELAY=$DEFAULT_DELAY
else
   DELAY=$1
fi

sleep $DELAY

screen -dmS cgm su user -c "/usr/local/bin/startcgminer.sh"
#### control x

#### nano /usr/local/bin/startcgminer.sh
#!/bin/bash
export DISPLAY=:0
export GPU_USE_SYNC_OBJECTS=1

cd /opt/miners/cgminer     #or where you put cgminer...i think this is the defualt location in linuxcoin
./cgminer -c cgminer.conf  # or whatever options you want
#### control x

#### make executable and change owner of the above files
$ sudo chmod +x /usr/local/bin/*miner*.sh
$ sudo chown root:root /usr/local/bin/*miner*.sh
####

that should do it....
coldreboot and see if it works.
