My computer boots to a black screen, what options do I have to fix it?

I'm having the problem with updating Nvidia. After updating the driver, I logged in and got a blank screen. I can change my background, but not much else. I can't even get to the terminal to do anything.

If I press Ctrl+Alt+F1, it sends me to this black screen that asks for my login and password. I've put in my correct information, but I still can't login.

This question was marked as an exact duplicate of an existing question.

It seems as though my video driver has crashed and taken Ubuntu along with it. – Louis Aug 17 '12 at 3:49
what is your graphics card? Is it optimus enabled system? There can not be any issue for username/password due to driver installation. – Web-E Aug 17 '12 at 4:07
which version of ubuntu are you using? I saw another question from you with same problem where you have mentioned you are using 12.10. If so please remember 12.10 is still in alpha stage and its expected to break – Web-E Aug 17 '12 at 4:22
I was using 12.04, but after I installed the driver, it said I was using 12.10. I have an Intel GMA graphics card. I've heard there were problems with updating nvidia, but all the fixes include using the terminal, which I can't pull up. – Louis Aug 17 '12 at 4:49
if you are haveing Intel GMA card why are installing nvidia? Have you enabled ubuntu update to fetch 12.10 ? See here – Web-E Aug 17 '12 at 5:00

What does lspci | grep VGA output? It might be the same issues a bunch of people are having with broken 3D on a certain series of nv30 hardware.

Does ubuntu-2d work?

Sadly because nvidia driver is closed source there isn't much we (people that don't work for Nvidia) can do to fix it. However the nouveau driver works well for 2d. (and the 3d rewrite in mesa is coming along)
