This initial bug report (kudos to the bug reporter for bothering) is about an upgrade. I can report the problem is the same with a new Natty install. I have removed "quiet splash" and run 'update-grub'. Still have the problem.
Used the solution for past versions. Added 'acpi=force' , updated grub and that works. Would prefer a better solution. Love that 90 days after validating the importance is undecided and it remains unassigned. And, yet when this problem appears many times in forum the standard response is: "Have you filed a bug report?" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/762203 Title: Computer is not turned off at shutdown -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
