Ubuntu 12.10 New Driver Installer UI
The new interface for handling Third-Party drivers has landed in Ubuntu 12.10 Quantal Quetzal (original story on WebUpd8)
The old and frankly comically unstable Jockey-GTK interface used for handling third-party drivers, has been replaced with a new "Additional Drivers" tab in software-properties and "ubuntu-drivers-common", which is, quote, "simpler and more robust than Jockey".
Given that poor old Jockey has fallen off the horse more times than I can count these last two releases, I am glad to see the back of it.
"software-properties-gtk" is known as "Software Sources" - you can run it from Ubuntu Software Center > Edit > Software Sources.
