Linux - New Video card upgrade

Right after you installed the card. Boot into recovery mode and go to text mode. Remove (or just rename) it:

Code:

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old

Then restart your computer. While you are in the desktop, go to 'Additional Drivers' and install the Nvidia driver.
