Cannot configure suspend-then-hibernate

[Larry Skywalker]

Configuring login to suspend-then-hiberrnate when the lid is off and configuring sleep so that hibernate happens 10 seconds after suspend, when trying to test with:

sudo systemctl suspend-then-hibernate

I get:

Failed to suspend system, hibernate later via logind: Sleep verb "suspend-then-hibernate" not supported

This could be a security vulnerability. If the user expects the system to suspend (and then lock) when the lid is off and it does not work, somebody could then just reopen the lid and get access.

You have 16G of memory:

> [ 0.081527] Memory: 15609664K/16134968K available

But you only seem to have 2G of swap:

[ 2.770354] Adding 2097148k swap on /swapfile

There is no way hibernation is possible on your system with this setup.

[Larry Skywalker (larryskywalker)]

I do not think that this bug report is invalid for multiple reasons (in order of importance):
1. The error message is not related to the root you identified. If the root cause is effectively a swap partition that is not big enough, maybe the error should say so.
2. The swap size was configured by the ubuntu installer. I would expect that the automatic installer configure the partition so that all the features are available, especially hibernate on a laptop.
3. Why would swap size have anything to do with hibernate? The system can dump memory in a regular file on the regular filesystem. Swapping is, as far as I understand, a way to extend memory when RAM is insufficient, not a way to store the whole volatile memory on disk.

Anyway, thanks for your time and effort.
