Same problem with 3.2.0-24-generic-pae (Lenovo T61). Shut down does not completly power off the pc, it just turns off the monitor. Suspend works fine.
Solved on my system with the following workaround. Run: sudo xdiagnose and disable VESA framebuffer driver and disable PAT memory. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/944772 Title: shutdown does not work To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/944772/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
