My computer boots to a black screen, what options do I have to fix it?
I've been having a problem with Ubuntu 11.10. I've tried installing it using Wubi, a USB stick, and a traditional install CD, but no matter what method I use, as soon as the GRUB screen disappears my screen goes blank. The backlight even turns off.
I'm on a Dell Vostro desktop, using NVIDIA Optimus graphics (it's a prototype). Most of the answers I've found elsewhere suggest installing drivers, but I can't do that because the system never boots.
This is a constant issue, by the way. I have yet to get even as far as the login screen. I know that my install image isn't corrupted, as I tested it on my laptop and it worked perfectly. Any help anyone can offer would be appreciated.
