Moving to some folder doesn't install it. You have to turn off x server and execute the pkg to install. (many question asked on this site , please search)

Additional drivers does the download and installation. (which is already done).

Know which driver in use by executing lsmod from terminal. There are two drivers for nvidia. One is open source nouveau and other closed source from nvidia (which gets installed if you install from nivida provided pkg ) . Either one of them is allowed and other will be blacklisted.

When you move the downloaded file this doesn't mean that is installed. you have to install it manually

To do that:

First press ctrl + alt + f1 This will open tty1

Now you are using the tty terminal console

log in with your user name and password

Now stop the lightdm(gdm or whatever) using the command

sudo stop lightdm

Then install the new driver with

sudo sh /path-to-the-driver
  • if something goes wrong close the installer and reboot then try again
  • still same problem the nvidia installer will make a black list in /etc/modprobe.d/
  • if this is not generated you have to make such file to black list nouveau
  • Run sudoedit /etc/modprobe.d/nvidia-graphics-drivers.conf and fill it with this: blacklist nouveau
  • If the problem is not solve you have to add the string "nomodeset" to your /etc/default/grub, in GRUB_CMDLINE_LINUX_DEFAULT=.... line
  • then update the grub

    sudo update-grub
