Don't offer Hibernate option if no swap

Hi Michael. Does this only hide the hibernate option from the GDM greeter? I haven't tried it, but my guess is that is probably the case. The problem is that the gnome-session dialog and FUSA will still offer hibernate even if there is no swap available, as they get the capabilities from HAL (and in turn - pm-utils).

I think this sort of thing should go in to pm-utils really

This only handles the GDM greeter. As I mention in the upstream bug (which is now closed, since that hibernate menu is Ubuntu-specific apparently -- I didn't realize), there are better ways of handling it (via hal like you mention):

"(B) It would be nicer to use HAL to ask the system if it can hibernate. We
could check power_management.can_hibernate which tells us if hibernation
support is even compiled into the kernel. And we could iterate over the
volumes, checking the fstype of each for "swap" -- a cleaner way to check for
swaps."

Which should be done in both GDM, gnome-session, and FUSA.

This patch just does it for GDM, and in the 'easy' way.

Sebastien may you have a look to the patch? Thanks.

This bug was fixed in the package gdm - 2.20.8-0ubuntu6
