I have ubuntu 12.04 running on my laptop. I've been trying to install a 2nd monitor on it, but ubuntu does not detect the second monitor. I have an nvidia card on my laptop, and ubuntu was using the nvidia driver.
So after reading a few articles on this site, one suggestion made was that the nvidia driver could be the problem and suggested not using them. So I removed them and rebooted my computer.
Well, it looks like a bad idea? Well, I turned on my computer, and I did see both screens display a login prompt and both screens looked fine. Then, shortly after, I see mostly black on the 2nd monitor, and a blocky purple background on my laptop monitor. I basically can't use my laptop, because I can't see anything.
So, how do I get myself out of this? Like, how can I restore my nvidia driver, when I don't even know what's going on in my screen?
