Best Answer

You need a couple of arguments to be passed to the Kernel at boot.

Run sudoedit /etc/default/grub in a terminal and edit the GRUB_CMDLINE_LINUX line so it looks like this:

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

Save and exit and then run sudo update-grub and reboot. That should be enough.
