Looking at the same webpage (http://vxlabs.com/2015/02/05/solving-the-ubuntu-14-04-nvidia-346-nvidia-prime-black-screen-issue/) in the comments ( by By JustAnotherCCppXXDummy) there is another and much simpler solution.

After you start your laptop (for optimus users - in nvidia mode), and getting the black screen of death ;), close your lid to put your laptop to sleep. Then open it and .... voila! You can now see the login screen.

This worked for me like a charm with the xorg-edgers 346 drivers.
