This bug is still in 16.04. I seem to be able to work around this issue by closing the display while in the bug. Let the display orientation update so only the external monitor(s) is turned on, then undock the computer and finally open the display and close it again.
But undocking the computer with the display open and then trying to make the computer sleep will always make it lockup so that the cursor is the only thing that's responsive. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1604313 Title: Ubuntu 16.04: system freezes instead of suspend after undocking To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1604313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
