Comment 0 for bug 1522117

With the latest qtmir (0.4.6+16.04.20151125-0ubuntu1) and unity 8 (8.11+16.04.20151126-0ubuntu1) packages on Xenial, when exiting an X app, the Unity 8 session "stops". I have seen it either go to the blank u-s-c screen or back to the Unity 8 greeter.

I don't have a crash file nor have I seen any interesting info in the unity8.log. If downgrade qtmir to 0.4.6+16.04.20151119-0ubuntu1 and unity 8 to 8.11+16.04.20151112.1, the issue no longer occurs.

When I get the blank u-s-c screen, I do see this in the application log:
