Re: impossible to install 8762 driver
According to your bug report, you booted into single user mode not runlevel 3:
root=/dev/hda2 ro single
The latest bug report looks the same as the rest, X is still crashing going through some fb code paths. At this point, my only guesses are that the nvidia X driver isn't installed correctly, or something else is unique about your environment, as no one else running Ubuntu has reported this problem.
