how to reinstall nVidia driver after system update

[curveu]

Hi everyone,

I installed system update and restarted my computer. The updates has been installed properly (because I saw the message saying "install updates and restart"). But after the restart, I can't get into my system. I can see the progress-bar loading and after that I can also see several messages (which also appears before). But now it just stops on a certain line and I can't get into my GUI. Is this because of the NVidia driver problem? I found the link below:

But now I need to figure out how to get into my system on command line and do this on command-line.

Thanks!
