[Bug 51465] ACPI suspend/hibernate doesn't work anymore

[Eric Schwartz]

Public bug reported:

Binary package hint: linux-image-686

This is a regression for breezy.

In Breezy, I had suspend/hibernate and resume working great with my hp
nc6220 notebook.  After upgrading to dapper, however, neither suspend
nor hibernate seems to work.

To initiate either, I select Quit... from the System menu, and then
select either Suspend or Hibernate from the screen that pops up.  In
both cases, I get a blank screen and password prompt, as if I'd selected
Lock Screeen.

dmesg shows no new messages when I select either option.  In
/var/log/messages, I see

Jun 30 14:49:41 localhost gnome-power-manager: Suspending computer
because the DBUS method Suspend() was invoked

or

Jun 30 14:53:58 localhost gnome-power-manager: Hibernating computer because the
DBUS method Hibernate() was invoked

depending on which option I selected.

This may be related to #50031, but the symptoms manifest themselves
differently here: in #50031, the thinkpad goes into a 'half-suspended'
state; here, it doesn't even try.
