After 45 minutes and trying several different suggested solutions,
scripts and adding genmon leading to repeated black screen episodes I
found a very simple solution. Turn off hardware acceleration in chrome.
Thought I would come back and post a update so maybe someone else might
try that first before posting here or adding scripts and programs.

Title:
  Black screen while playing youtube video in chrome.

Status in xorg package in Ubuntu:
  Expired

Bug description:
  I have an Acer Extensa 5620, with GMA x3100 video chipset. When using
  Chrome or Chromium to play videos on Youtube the screen goes
  completely black and I could not revive it. The audio is played during
  this. I have been using Xubuntu and Chrome for about a year,  and have
  only been experiencing this for a few months. As I recall this came in
  around the upgrade that brought in the little icon in the status bar,
  that shows Chrome running in the background even when the windows are
  closed. I tried reinstalling the newest LTS Xubuntu (14.04), still no
  good. With Firefox it works just fine. I guess it could be something
  about hardware acceleration, but it is a shot in the dark.

  
  So summarized: I tried to play Youtube videos on Chrome and Chromium.

  I was expecting it to playback as it had for years before.

  It did not, the screen went all black, audio started playing, and I
  could not bring the screen back to showing anything. This has happened
  a dozen times, and always happens when trying again.

  Thanks!
