Can't activate proprietary driver for NVIDIA from "Additional drivers" Ubuntu 14.04
I'm using Ubuntu 14.04,64 bit, with nvidia 610M dedicated graphics card.
By default when I go to "Softwares & Updates" > "Additional Drivers" it shows "Using X.Org X server-Nouveau display driver..." selected.
But I wanted to switch to proprietary nvidia driver so I selected "Using NVIDIA binary driver-version 331.38..." and clicked "Apply Changes" but shows a progress bar and after few seconds the "Nouveau" driver again shows selected.
apt-get update from the terminal.
Did a reboot after "Apply Changes"
But still no luck.
