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
does not seem to do anything.
As far as I understand, now that ubuntu has switched to systemd, the correct command would be
Failed to hibernate system via logind: Sleep verb not supported
I tried the solutions mentioned here, 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 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?
