Hey I have the same problem as this (pm-hibernate not doing anything and not producing a log file, hibernate option greyed out in every interface), except I'm on xubuntu, not sure if that makes any difference. I followed the steps described in the chosen answer, and it still doesn't work (also, pm-is-supported --hibernate does not seem to do anything either).

Maybe I misinterpreted how I was supposed to edit /etc/default/grub. Currently the corresponding line is set to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash UUID=da462d1a-465f-435a-acec-1689eeaca9a6"

Alright I'm stupid, you have to boot the tuxOnIce kernel instead of the default one. Now pm-hibernate works just fine.

One weird thing though, it doesn't seem to recover from hibernation (hangs on "loading initial ramdisk" for up to 2 minutes) if I don't use the tuxOnIce (upstart) option. Anyone knows why ?
