Comment 27 for bug 1310058

About power management settings being ignored, please ask on the forum of Ubuntu (or the distro you are using) or open a new bug. It should be unrelated to this bug, you just never saw this problem because you were never able to hibernate at all.

That hibernate fails, is yet another different problem. It is by design that the encrypted swap created by ecryptfs-setup-swap won't work with hibernate. I think it has been discussed at length in other bug reports or on forums already, with other encryption methods (such as encryption with a password instead of a random key) being suggested as solutions. Not encrypting your swap would of course allow you to hibernate as well.

In short, you already fixed the problem which this bug describes, the other problems which are left to fix are beyond the scope of this bug.
