So the journal goes to the "bitter end" when it's supposed to turn off the computer, so nothing really useful there. I have no immediate idea here, just perhaps some debugging tips.
I also noticed that sometimes shutting down causes the screen to freeze/go black, I attributed that to a graphics driver bug when shutting down lightdm/X.org (I sometimes get a similar effect when switching users). Does this also happen if you switch to a VT before shutting down? You can use sudo systemctl poweroff, or sudo poweroff (should be by and large the same). Another thing is, perhaps it shows some more things if you boot with "debug"? that'll activate kernel debug messages too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1427672 Title: System doesn't power off when shutting down To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1427672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
