I installed Ubuntu 14.04.3 LTS with GNOME Shell 3.10.4 a couple of days ago. I have been following Wendell's video on TekLinux to install this system. I just have sort of a noob question about adding PPA's to the system.
I found this source for Nvidia PPA's - https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa
Is this the correct place to obtain drivers? On the webpage it says: "You can update your system with unsupported packages from this untrusted PPA by adding ppa:graphics-drivers/ppa to your system's Software Sources."
The two words that spook me are unsupported and untrusted. Does this just mean that the official ubuntu devs haven't supported or acknowledged this ppa yet?
