Yes. This appears to be a unity bug. Shutting down from GDM does not result in the complaint from the BIOS. The shutdown from the unity menu shuts down the computer extremely fast (<3s); I don't see the purple plymouth screen. The shutdown from the GDM menu takes in the order of 10s, and I see the plymouth screen with the shutdown dots.
Ergo I think the fix is to change whatever shutdown routine the unity menu calls to either delegate to the GDM routine, or to do substantially the same thing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776803 Title: Natty does not shut down cleanly (enough for my BIOS) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/776803/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
