I recommend to download and install the driver from nvidia directly. Following steps are necessary:
store it in a folder, e.g. /tmp/NVIDIA###.run
Close all running programs and save all changes to any open documents!!!
Switch to plain text console (CTRL + ALT + F1) and log in as normal user
make the .run file executrable with:
chmod +x /tmp/NVIDIA###.run
stop the graphical window manager:
sudo initctl stop gdm
install the driver:
/tmp/NVIDIA###.run
Follow the instructions - warnings might appear but usually can be considered harmless
restart the graphical window manager:
sudo initctl start gdm
switch back to workspace by pressing CTRL + ALT + F7 or F8
(replaye NVIDIA### by the original filename of the file downloaded)s
