I'm using Ubuntu 14.04 64bit, after install nvidia binary driver 331.89 from Additional Drivers application then reboot, it shows black screen, no login window, I even can't use ctrl+alt+F2 to switch to text mode, then I reboot and go to recovery mode, use 'prime-select intel' to switch to intel GPU , every thing is fine, but as soon as I switch to nvidia GPU, still same issue.
OS: Ubuntu 14.04 64bit
Laptop: HP ENVY 15t Nvidia GeForce 740M + Intel HD 4600
Desktop: Unity
