Bug Description
Hiberation doesn't work in Precise (worked in Oneiric) on my Dell XPS 13. I can add the following to /etc/polkit-
[Configura
AdminIdent
However, if I hibernate, starting the machine just does a normal boot and does not restore the previous state. The swap is large enough for hibernation:
Filename Type Size Used Priority
/dev/zram0 partition 1966796 0 100
/dev/sda5 partition 4077564 0 -1
Mem: 3933596 1004176 2929420 0 44304 449540
-/+ buffers/cache: 510332 3423264
Swap: 6044360 0 6044360
I am happy to help with debugging or testing.

I'm investigating this on my HP Mini netbook.
The fix in /etc/polkit is already present on my precise build, still no hibernate option.
One apparent gap in the build is a kernel command line argument to indicate where to find the hibernate image.
I've got this now; the 'resume' argument, but I can't initiate hibernate (via the GUI) so can't test it -
$ cat /proc/cmdline /vmlinuz- 3.2.0-20- generic- pae root=/dev/ mapper/ valiantvg- lv00sys00 ro resume=/dev/sda2 quiet splash vt.handoff=7
BOOT_IMAGE=
based on docs here, this is required
https:/ /wiki.archlinux .org/index. php/Pm- utils#Hibernati on_.28suspend2d isk.29
added it by amending
/etc/default/grub as follows ..
GRUB_CMDLINE_ LINUX_DEFAULT= "resume= /dev/sda2 quiet splash"
and then running sudo update-grub
