How do I install the latest Nvidia drivers via the Additional Drivers tool?
Drivers in the Additional Tool
will never be updated to higher versions unless there is a very big issue with them. You need to either add the PPA or update manually.
Upon a Ubuntu release packages are frozen in time only to be updated in case of major problems and bugs. Adding this PPA will update your drivers to the latest versions using packages packed by the Ubuntu team.
The System 76 folks maintain a PPA with just the nvidia drivers in them, so you can use this for just about any machine with an nvidia driver. The nice thing is they keep this PPA up to date with the latest upstream nvidia driver, making this PPA ideal for gamers.
If you already have the drivers installed in your system via the Additional Drivers
tool
Add the System76 driver PPA (that includes Nvidia drivers)
sudo add-apt-repository -ys ppa:system76-dev/stable
Update and upgrade
sudo apt-get update && sudo apt-get install system76-driver-nvidia
Then either restart the X server or reboot.
How to remove/uninstall these drivers
Install ppa-purge
sudo apt-get install ppa-purge
Purge the system76 team PPA
sudo ppa-purge ppa:system76-dev/stable
Since it's an old (2015) question the previous answers are a bit outdated. The system76-dev/stable
ppa does not seem up to date. Proprietary NVIDIA drivers are removed from bleeding edge xorg-edgers
PPA but can be found now in the graphics-drivers
PPA.
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
