While loading YouTube videos on Ubuntu 14.4 my screen goes black and yet everything still works, lights on the keyboard and the video plays. No amount of pressing buttons (ctrl+alt+f1, power button, mouse clicks etc..) can get the screen to turn on again. I've had ubuntu 14.4 for a few months now and this error started appearing yesterday and continues to black screen whenever i load YouTube.
The only fix I can find is by hard shutting down the computer and restarting. That gets the screen to work, yet if i load youtube it repeats.
My computer (laptop) is fairly old now and it maybe be a hardware error, yet i've been on 14.4 for a few months now and unless it was a new update i doubt it's my hardware.
I'm not the only one having this problem: Laptop screen goes black, but laptop still running https://askubuntu.com/questions/538392/laptop-running-ubuntu-14-04-screen-goes-black-while-playing-youtube-videos
I believe this error needs serious attention now and it may be due to a recent update as most people who have this error have posted on it recently.
Here are my pc specs: http://i.imgur.com/YlsHtuH
I'm willing to provide any information possible and thanks in advance for your interest in this problem!
edit: I have found that if i don't have the tab with the video open, the screen doesn't black out. -des
