Upgrade Linux Ubuntu Kernel graphics drivers to latest version

Upgrading these user-space driver components is as easy as running either

sudo apt-add-repository ppa:xorg-edgers/ppa
or
sudo apt-add-repository ppa:oibaf/graphics-drivers

for linking your system to either archive. That's then followed by running:

sudo apt-get update

to update the package meta-data and lastly:

sudo apt-get dist-upgrade

for upgrading all of your operating system's packages.
After that, reboot, and if all goes well you'll be running the very latest Linux graphics drivers.
