Comment 1 for bug 1013375

Is this a laptop or a desktop?
Has it done this from start?
Do you have extension for Banshee?
Do you have any screensaver (installed/active)?

Cinnamon has it's own bugtracker:
https://github.com/linuxmint/Cinnamon/issues?page=1&state=open
but I think that this comes from the underlying Gnome components, so the link you provide in the bug description probably apply to your case. This could be a duplicate of https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/893696

Try the settings in:
gnome-power-preferences
(Run that "gnome-power-preferences" from the command line. I'm not on Cinnamon right now so I don't know for sure this is the same but it should be)
