Black Screen on Macbook Pro 6,2 After Installing 12.04LTS - Tried Everything Already

[jart16]

I am tri-booting Mac OS 10.6.8 (Snow Leopard), Windows 8, and Ubuntu. I installed via a USB drive. The install and the LiveCD trial went flawlessly, and I can boot into GRUB. However, as soon as I press Enter on the installed Ubuntu, it brings me to a black screen. I left it there for about an hour, and it was still black. No words or anything. The video card is an nVidia 330M. I tried 13.04, and that worked, but it wasn't 100% compatible, so I much prefer the LTS. So far, I have tried:

Failsafe Graphics
Reinstalling
Putting nomodeset and no splash in GRUB
The custom Mac LiveCD (wouldn't boot from the USB drive)
Adjusting my brightness (believe it or not, that's a common solution)
Switching graphics mode through GRUB (got a garbled mess, but I think Unity was running in there somewhere because my backlit keyboard lit up)
Entering --quiet splash nomodeset and quiet splash nomodeset (brought me to the splash screen with orange dots, then kicked me back out to a totally black screen)
Pressing Esc during the splash screen (gave me a bunch of checks, all came back [OK], but kicked me to the black screen again)
Keep in mind, I'm kind of a beginner. I know much more than the average beginner, but I wouldn't call myself intermediate just yet.

One more thing: the black screen I'm getting is NOT backlit, and there is NO blinking cursor. It looks as if I turned the computer off, but the fans are still running and I think the hard drive is still doing something)

You might want to look in the Xorg logs (/var/log/Xorg.0.log) for lines containing "(EE)". They should point to the error(s).

(EE) Failed to load module "nv" (module does not exist, 0)

I looked up a fix, but how do I apply it via recovery root or LiveUSB? These solutions assume that you can get into Gnome in the first place

Could you please post what you did to fix the issue? It's been quite a few months since your post, so I'd imagine that you have gotten this resolved?

Thanks!
