I installed on Ubuntu nvidia-331-updates and nvidia-prime. The bug that i found is that when i select the Nvidia graphic card Unity and Compiz do not start. I emphasize that opening the nvidia-settings the only items on the menu are "PRIME Profiles", "Application Profiles" and "nvidia- settings Configuration". I could not copy the terminal output when I launch Unity, but if it is necessary, I can reinstall Ubuntu and try to copy it.
