Affects me as well. Dell Precision M6600 64 bit Ubuntu 11.04 Ubuntu 11.10
The laptop was on bios A03 which I updated to A07 and disabled "c state control" in bios after a few attempts but still no joy. Removing the AC connector before issuing the shutdown command within gnome did allow for a clean power down. Later, I stopped acpi-support but left AC connected and the system also successfully powered down. I'm currently running 64 bit 11.04. I'd consider going back to 10, but it EOL next month. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/882817 Title: shutdown screen stuck after upgrade to Ubuntu 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/882817/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
