I have installed latest nVidia graphic driver via this PPA "xorg-edgers/ppa". Now in Nvidia X server setting showing the driver version is 346.35. But in Ubuntu's Additional Drivers there is no such driver rather it marks the Nouveau driver.
lspci -vnn | grep -i VGA -A 12.

Which version of graphic driver I am using currently ? If I am not using nVidia's driver then how can I use nVidia's driver. I am running Ubuntu 14.04 64bit OS.
