Just made a clean install of Ubuntu saucy and this started happening to me sometimes.
I believe the issue happens due to systemd-logind, which is set to always standby a laptop when you close the lid, and the supposed solution can be found here: http://askubuntu.com/questions/360615 /ubuntu-server-13-10-now-goes-to-sleep-when-closing-laptop-lid (the HandleLidSwitch=ignore option). Because this doesn't happen always I can't be 100% sure; I'm running with that option set for a few days, and if the issue never happens to me again I'll report this as a systemd-logind bug. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/471457 Title: Shutdown does not have priority over suspend/hibernation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/471457/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
