I installed Kaos on a clean disk and let calamares installer to do the job for me. I chose the option "Swap with Hibernation". I tried to hibernate, but when I click the power button after that, the system does not wake up and is stuck at a black screen. Now as hibernation is not working, I reinstalled the system with no swap.
