My system is unable to resume after I suspend it(by closing the lid directly or through terminal or by clicking the suspend option from the screen). As soon as I try to resume, screen gets awake but shows nothing. Eventually, I have to force shutdown it by long pressing power button and restart the machine. My machine is dual boot with Windows 8. Ubuntu 14.04 runs in a partition.
