I have a problem with my Ubuntu OS that I've been trying to solve for the past 2 weeks with no results. I've probably put 14 hours into solving this problem.

When I use the suspend option on my computer, it breaks the operating system. The OS suspends as it normally should (dark screen, blinking power light, etc.) but it does not wake up properly. When I try to wake it up, the backlight turns on and the fan starts and everything but the screen is black. I've tried different key combinations (CTRL+ALT+F2 for example), putting in USB drives, pressing the power button, but none of it will turn the screen bright. The screen stays frozen black and the computer is running as if it were awake (fan whizzing and stuff).

I am forced to hard restart the system every time I choose the suspend option.

Hibernate is similar. When I type

sudo pm-hibernate

the computer will go dark, but will not power down. If I move the mouse it will turn back on to a black screen with a blinking cursor. CTRL+ALT+F2 will go to a terminal window, but upon typing anything in the terminal window will freeze.

I've tried a number of ideas including all of them here: Ubuntu freezes/crash after wake when upgraded to 13.10 and here: http://wafflesatnoon.com/2012/11/17/ubuntu-suspend-wont-wake-up-my-quest/

Help?

Could it be that your screen brightness is set back to 0? Try to increase your brightness with the Fn keys. –  OrangeTux Jan 23 at 15:54
    
I have tried increasing the screen brightness also, to no avail :( If that were the problem though it would be strange since my computer cannot go that dark –  Paul Terwilliger Jan 23 at 16:09
