So I have the AMD R5 M430 video card, but there is no official driver so I wanted to seek some open source drivers, and I found this Ubuntu 14.04.5/16.04/16.10 and AMD graphics and after all I read Oibaf's driver (https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers) fits good, but I don't know how to install it.
I want a good driver for this video card beacuse I want to use it for gaming and other stuff, I mean I want to use it and ditch the Intel video card beacuse I hate it and I don't want to use it.
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:
It should download automatically and install and set up the driver for you.
Hope this helps!
