Question! How do I install the latest graphics drivers for my GPU (ATI AMDGPU) and the latest mesa under Kubuntu 16.10 (also available for 16.04)?
Answer! Open up a console then type in the following command:
sudo apt-add-repository 'ppa:paulo-miguel-dias/mesa'
Then push the enter key, and run the next command:
sudo apt update && sudo apt upgrade
Note! after this do a reboot and you should be running the latest mesa and AMDGPU drivers with OpenGL 4, to make sure you can check with the following command:
glxinfo | grep "OpenGL"
Note! If the terminal complains about glxinfo not being available, you should install mesa-utils, just do a:
sudo apt install mesa-utils
