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 BOOT_IMAGE=/vmlinuz-3.2.0-20-generic-pae root=/dev/mapper/valiantvg-lv00sys00 ro resume=/dev/sda2 quiet splash vt.handoff=7 based on docs here, this is required https://wiki.archlinux.org/index.php/Pm- utils#Hibernation_.28suspend2disk.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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/954668 Title: Hiberation doesn't work in Precise (worked in Oneiric) on Dell XPS 13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/954668/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
