I have a fresh install of 16.04.1 on a Lenovo T450s that always worked fine with respect to suspend/hibernate on Ubuntu (previous version I used was 14.04.5). Swap is comfortably bigger than RAM on this install.

As I am used to now, after the install I tried to go on with the usual hack for hibernation activation. However, things seem to be different this time as `sudo pm-hibernate`
does not seem to do anything.

As far as I understand, now that ubuntu has switched to systemd, the correct command would be `systemctl hibernate`
which returns

```
 Failed to hibernate system via logind: Sleep verb not supported

```

I tried the solutions mentioned [here](https://askubuntu.com/questions/768136/how-can-i-hibernate-on-ubuntu-16-04), but they are mostly aimed at re-enabling `pm-hibernate` and making it an entry in the logout menu. I also saw that one possible [solution](https://askubuntu.com/questions/761394/why-isnt-hibernate-in-ubuntu-16-04-working-and-how-to-fix-it) is to install the Tuxonice kernel, but did not try as I am not very keen on tampering with the kernel in general and using a PPA kernel in particular.

So, is there a way to reactivate hibernation on the last, systemd-based versions of Ubuntu? Preferably using systemd, and avoiding potentially system-breaking hacks. Or do I just have to wait and hope until the next update?
