#On a clean install of Ubuntu 16.04, how to get the best hashrate out of your cards (prior to OCing and BIOS flashing)

sudo apt update
sudo apt dist-upgrade

#Install version 17.40 of the AMDGPU-PRO Linux Drivers:
cd /opt
sudo wget --referer=http://support.amd.com https://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-17.40-492261.tar.xz
sudo tar -Jxvf amdgpu-pro*
cd amd*
./amdgpu-pro-install -y

#Revert to an older version of the kernel which has higher hashrate (I used 4.9.50)
#(due to a security fix in the new kernel version - over 4.10, hashrates dropped by more than 30%)
cd /tmp/
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9.50/linux-headers-4.9.50-040950_4.9.50-040950.201709131832_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9.50/linux-headers-4.9.50-040950-generic_4.9.50-040950.201709131832_amd64.deb

sudo dpkg -i *.deb


# Remove the older kernel images (i only had 4.13, so i ran the following command):
# You can see what versions you have by pressing tab after you write 'sudo apt-get remove linux-image' 
sudo apt-get remove linux-image-4.13* && sudo apt autoremove -y


# Check if your user is already part of the 'video' group (the word 'video' should appear among the others)
groups

# IF not, run the below
sudo usermod -a -G video $LOGNAME
sudo reboot

#If you don't have it already, install new ROCm Kernel (otheriwse skip this step):
sudo apt install -y rocm-amdgpu-pro
echo 'export LLVM_BIN=/opt/amdgpu-pro/bin' | sudo tee /etc/profile.d/amdgpu-pro.sh

#Edit grub
sudo nano  /etc/default/grub

#2MB fragments for Ellesmere are enabled with a grub option:
GRUB_CMDLINE_LINUX="amdgpu.vm_fragment_size=9"

#After exiting grub editing, do:
sudo update-grub 
sudo reboot


#How to to run the miner on startup 
#First of all, make sure that your computer is set to automatically login on start-up 
#(without you having to put the password)

#Next, make sure that in the script that runs your miner, the path to the command is the absolute path 
#(so it will run no matter what folder you call it from
#IE if running Claymore, make sure the command starts like /path/to/miner/ethdcrminer62 instead of just ethdcrminer64
#oPEN STARTUP APPLICATIONS ON UBUNTU AND ADD THE FOLLOWING COMMAND
gnome-terminal -e 'bash -c "/path/to/miner/start.bash; exec bash"'

sudo chown root:root /path/to/miner/start.bash
sudo chmod +s /path/to/miner/start.bash

sudo reboot 
#After this you should see the miner run in a terminal window
