Hibernation in LL


I'm reading about 'Suspend to idle', a newer way to suspend to memory with faster wake-up time and identical energy savings to S3 (suspend to swap).

Any idea if this can be achieved on LL?

I tried 'systemctl hibernate' on LL, and it fails. This is having a swap partition larger than ram. It kills networking, the screen goes blank, but rather than going to sleep it goes back to desktop.

Any ideas? Thanks
