I did an update today and updated ubuntu-drivers-common. I tried installing nvidia-331 again with all its dependencies (installed nvidia-prime and other stuff together) and rebooted. I didn't even see a login screen, the computer hanged in a black screen. I wasn't able even to switch to a terminal with Ctrl-Alt-F1 to provide you the logs that you requested.
I rebooted with the previous kernel and took a copy of the logs. I don't know if they are useful to you, but take them anyway.
