Confirming here. I noticed my desktop system had done this last night. I booted it up and was away for a couple of hours to find it had hibernated again.
I checked my settings and they were set to "Don't Suspend". The "When power is critically low " dropdown setting was showing a blank value, as if neither Hibernate nor Shutdown were selected. I changed the values in both boxes, then moved them back to "Don't suspend" and "Hibernate", to see if this is just a misreading of legacy settings by some update of the program. I'll let this system sit for a couple of hours now to see if it worked. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/864479 Title: System goes to hibernate or suspend even when set to "Don't suspend" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/864479/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
