It's possible that during install a user or OEM may opt to not include a swap partition due to being worried about wearing the SSD down sooner. When this happens, hibernate won't work because there is nowhere to write the memory out to.

Rather than trying and failing in a known failure situation, the FUSA applet should only present the option if the swap partition is present - AND large enough to accommodate the amount of ram that needs to be written to it during a hibernate request.

This should be in HAL because HAL shouldn't be reporting can_hibernate if the user doesn't have a swap.

There is also the possibility to use a swap file instead of a swap partition.

I think that this should have higher priority than Wishlist. If the system is incapable of hibernating, there shouldn't be an option to do so.

Please see bug #432598 for more details on how S4 can be disabled in Lucid via PolKit.

We need someone to confirm whether or not this is also triggered by lack of a swap partition for Lucid.

In Ubuntu 10.04 ..Hibernation is not exposed in UI if no swap is on system.

[Mario Limonciello (superm1)]

Jerone, if I'm not mistaken, it doesn't check the size to make sure it
really can hibernate. It still falls over in that scenario.
