Comment 2 for bug 1326537

I also have a clean installation of Mint 17, 64-bit, Cinnamon and the suspend and power off functions do not work.

Screen goes black with small icon in center screen but computer keeps running and unable to regain control and have to use hardware power button or reset button to regain control.

The screen saver works but the STR function does not.

I have not been able find a solution to the problem - most frustrating for what is otherwise a great OS.
