Bug Description
Since upgrading on Ubuntu Gnome 15.04 from Gnome 3.14. to Gnome 3.16 I have noticed that on occasions, when I awake my machine from suspend, the screen will simply stay black, even though I press the power button on my laptop and it lights up and stops just flashing on and off, and I also hear my disk getting ready for action, or whatever the noise is I always hear when I awake my machine from suspend, my screen is still black, without even any back lights. And I am forced the power down the machine manually and restart.

Although that was in Gnome 3.14, the issue is still present in Gnome 3.16.
Here is a portion of syslog from the last time it happened (19:56:33 was when I closed the lid of my laptop, and 23:15:40 was when I opened it again):
