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

@brandon211: good to know that there is a workaround, however I think it is not really a solution because the kernel you are currently running is not the default one. I am also running Ubuntu 16.04.2 but with the standard kernel 4.4.0-64-generic where this bug is still present. Furthermore

As the person who originally filed this bug, I'd like to add a comment: The bug actually doesn't affect me anymore to the effect that when Ubuntu 16.04.2 came out I switched to the new hwe-stack. This means I am (by) now running kernel 4.8.0-39-generic which does fine so far. Anyway, it would

I have the same laptop and am experiencing the same bug. I have tried upgrading to 4.8.0-30-generic but that does not fix the problem for me. I did try and turn off all monitors except the laptop monitor before undocking and that allowed me to put the laptop to sleep. I could not wake it up,
