I have Xubuntu 14.04 amd64 and this is how i fixed my black-screen
problem. My hardware is Dell R15 N5110 with hybrid graphics Geforce M525
+ Intel HD 3000. Left display is LVDS and right is HDMI.

Currently i have nvidia-355 and it works fine.

Bug description:
  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 and reboot, everything 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 GT 740M + Intel HD 4600
  Desktop: Unity
  Kernel: 3.13.0
  CPU: Intel® Core™ i7-4700MQ

  Thanks!
