Marked bug 1394388 as duplicate of this. The bug report points out an additional related symptom, as follows.
When issuing the pm-suspend command, the scripts set the HIBERNATE_MODE in /sys/power/disk to "suspend". There is some shell magic to save the previous setting in variable HIBERNATE_MODE_SAVE, but this fails under the default shell /bin/dash (works correctly with /bin/bash). Effect: if you use pm-suspend once, the effective HIBERNATE_MODE in /sys/power/disk stays in "suspend", and any subsequent pm-hibernate will also just do a suspend instead of "platform" or "shutdown". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1548392 Title: Fix for 1172692 fails to restore hibernation mode with suspend-hybrid To manage notifications about this bug go to: https://bugs.launchpad.net/pm-utils/+bug/1548392/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
