Hy all!

The problem is not only on nVidia cards!

The same thing (black screen on Ubuntu) happens on AMD ATI cards also!

The problem seems to be due to the fact that Ubuntu and derivates
distros based on Ubuntu (Mint, Mate, etc.) detects an unreal, extremely
high Graphic Processor Unit temperatures from GPU sensors (DOUBLE THAN
THE REAL VALUES), and then Ubuntu kills the graphic output in order to
protect the graphic card from overheating.

For more details read this post here: 
http://askubuntu.com/questions/655200/black-screen-ubuntu-14-04-a-possible-cause

The post is way too big to copy/paste it here.

Please check the GPU sensors temperatures on Ubuntu 14.04 also within
your systems.

Of course that can be done only by those who systems are still showing
at least the Ubuntu desktop, in order to run the Terminal.

I hope that somewone will find a solution for this BLACK SCREEN issue.
