In my fresh install of Linux Mint 16 with MATE, I have no hibernate option in the Power Manager; only suspend and shutdown.
In the Quit menu I have hibernate as an option. Also
sudo pm-hibernate works from the command line.
Any suggestions of how to enable hibernate in the Power Manager? I want to hibernate when the laptop lid closes.
I have just enough swap space for hibernation to work:
