I've recently installed a Nvidia GTX 660 into my Ubuntu (20.04 LTS) box. The BIOS is configured correctly to have the discreet card be the active graphics engine, however, Ubuntu isn't detecting that it's there. I've pulled all the lists and the only graphics I can find on the system are the Intel HD 4000 that's built in. I've installed drivers for it, but it's still no go.
Any assistance would be appreciated. Ubuntu is not my usual OS so I'm kinda stumbling around in the dark here.
I've verified the card is working by installing it in my Windows box and it came up with no issues.
