#38 didn't do it for me
#18 is more complicate than putting laptop to sleep & back on on nvidia boot (to keep the ability to switch easily between graphic card)

however,   KUZnets has written a script to work around but haven't
tested it although it sounds very good;

see KUZnets comment,  March 08, 2015 9:49 PM here :

prime-black-screen-issue/

if someone (less noob than me) could confirm this a decent workaround
(for laptop user at least) that won't create more problem than it solves
? thanks

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.
