This is how to setup Makulu LinDoz to use AMD GPU PRO driver needed for the Newer AMD GPU’s to operate correctly !

Preparation
Download the amdgpu-pro tar archive containing the installation script (eg. to ~/Downloads). This is the Modified for debian version compatible with all Makulu 14 OS’s
https://mega.nz/#!qZMFhIpY!tXwp3NWs-MfJADcEpJ9Ydz6HIbWKf1gOoIs_9VyRFtE

open the folder where you downloaded it too then right click and Extract it
amdgpu-pro-17.50-511655.tar.gz

Enter the directory where the downloaded archive was extracted (this is expected to be the same name as the archive
file).
cd ~/Downloads/amdgpu-pro-17.50-511655

Within the Complete Graphics and Compute Stack, newer hardware will require a different OpenCL component to be
installed. Please choose the correct install based on your installed Graphics product.

Vega10 and newer includes AMD R9 390X DD Black Edition like mine!
Install the Complete Graphics and Compute stack
./amdgpu-pro-install -y –opencl=rocm
Reboot

pre Vega10
Install the Complete Graphics and Compute stack
./amdgpu-pro-install -y –opencl=legacy
Reboot

Uninstall
Removal of all components is accomplished by simply running the uninstall script from anywhere in the system.
amdgpu-pro-uninstall
Reboot
