Installing Oibaf's Drivers for AMD R5 M430 on Ubuntu 16.04
With your instructions you linked, they seem kind of crazy, but really they are very easy to install. From a terminal window, run the following lines:
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade
It should download automatically and install and set up the driver for you.
Hope this helps!
