How to install a second graphics card and use 4 monitors?
I finally decided to take the plunge and ditch windows. After several hours I got things working perfectly with all my apps installed. Only problem is that I run 4 desktop displays off 2 nvidia adapters, the first adapter (GeForce GT 240) with two screens work perfectly but can't seem to get the second adapter (GeForce GT 620) installed. Using Ubuntu 14.04 LTS (AMD64)
Please help me with simple instructions please. Terminal info to follow:
