> Hibernate (suspend to disk) has been disabled by default, as it was found to be unreliable, very slow and confusing to have two suspend modes. See bug 812394 for details. If you want to re-enable it, please follow this recipe.

As someone who runs Ubuntu on a laptop with a dead battery, that's somewhat unfortunate.

Ouch! I'm surprised a bug that big with a default application wasn't a release blocker.

Hibernate actually works on many people's computers, to see if does on yours, test it at the cmdline:

$> sudo pm-hibernate

Then turn it back on. If everything works ok, you can permanently add it back to the system menu with these scripts:

Need two files:

Instructions and links to more detailed instructions in the .sh comments.

Evolution is no longer the default mail client. It's now Thunderbird (and I think it has been since at least 11.10).

That probably just means the 'hibernate' option was removed from the dialogs. You should still be able to invoke it from the power management tools via a terminal. I'm not on ubuntu but does this still work:

'pmi action hibernate'

I'd guess from the phrasing that suspend-to-disk can still be enabled, it just isn't by default.

[jamesgeck0]

Yes, it can be, and the next bit says as much. I've pasted in the rest of the bullet point to clarify. I was just disappointed that such a thing has to be enabled manually now.

I find STR reliable, stable, fast and good enough that I think hibernation isn't really needed any more...

[lukeschlather]

Hibernate is a must-have for long travel without outlet access.

Suspend to Ram is great, but my battery dies by the morning in this mode. Plus I figure if I ever buy an SSD, hibernate will be my preferred option.

[idleloops]

Oh well. I agree with you on this one being a bit of a show stopper, even if there are applicable workarounds.!
