Execute : sudo apt-add-repository ppa:graphics-drivers/ppa Why does it work? While adding the Launchpad PPA back, you see : gpg: requesting key 1118213C from hkp server keyserver.ubuntu.com

Using the official repos is making sure that the software you're installing is both tested and configured as it should be, in order to function as it should.
