My graphics card isn't being detected by Ubuntu. It's running off the on board graphics not my EVGA GeForce GTX 750ti FTW. I'm not sure what to do and I'm not sure how to download my drivers.
Open a Terminal and use the following commands in order and enter your password when it asks you:
sudo add-apt-repository ppa:xorg-edgers/ppa -y sudo apt-get update sudo apt-get install nvidia-current
This will install the latest nvidia drivers for your graphics card if it is not recognized in the additional drivers tab in software & updates.
