  * Make sure initiate and terminate callbacks are not empty before
    calling them. (LP: #1605012)
  * Properly destroy close_button_ to properly disconnect lambda. (LP:
    #1605010)
  * Use the standard notification-device-eject in the "device eject"

    setups. (LP: #1605231)

    add "move" and "resize" plugins as requirements. (LP: #1506023,
    #1605007)
  * When locked discard damages from windows below lockscreen. (LP:
    #1605180)

When I be able to get that fix on Ubuntu 16.04? Bug still here:
unity/xenial-updates,now 7.4.0+16.04.20160715-0ubuntu1 amd64 [installed]

[Andrea Azzarone (azzar1)]

It's already fixed in 16.10 and we already started the SRU process to bring the fix to the regression in 16.04.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Konstantin (ivankin)]

May also be helpful:

When I lock and try to change language in the login screen (Alt+Shift), it flashes as described showing me the desktop for a moment.
When I then log in successfully, Shut Down option doesn't work as expected, throwing me out to login screen.

But if I lock and NOT try the language switch, then Shut Down works fine.

Anyways, Ubuntu and lightDM are awesome :p

[Alex Athanasopoulos (filopodaros)]

duplicate bug #1609236 seems to be fixed. I can now switch back to English in the screensaver lock screen. My version of unity is 7.4.0+16.04.20160715-0ubuntu1. It also no longer crashes when I press "Ctl-Alt-Del".

[Egor Ignatenkov (phat1984)]

I also have unity version 7.4.0+16.04.20160715-0ubuntu1 and I still have this bug. What are the plans of releasing the hotfix to 16.04? It's quite annoying.

[Marco Trevisan (Treviño) (3v1n0)]

A SRU is in progress, it will be released soon.
