** Description changed:

- On Wily, updated daily:
+ [Impact]
+ dm-tool add-nested-seat doesn't work anymore.
  
- petter@odin:~$ ac policy lightdm
- lightdm:
-   Installed: 1.16.6-0ubuntu1
-   Candidate: 1.16.6-0ubuntu1
+ [Test Case]
+ 1. Log in
+ 2. From a terminal run "dm-tool add-nested-seat"
  
- petter@odin:~$ dm-tool add-nested-seat 
+ Expected result:
+ A window opens with a login screen
+ 
+ Observed result:
+ A window opens with a black screen. An error is reported in the terminal:
  Unable to add seat: GDBus.Error:org.freedesktop.DBus.Error.Failed: Failed to start seat
  
- I was hoping to get a nested X server with lightdm, but  the Xephyr
- windows briefly opens and then closes again. I have tried this on two
- different installations of Wily with the same results. If I try to start
- Xephyr manually and then start lightdm on it with 'dm-tool add-
- local-x-seat' then dm-tool fails with exactly the same error message as
- above.
+ [Regression Potential]
+ The code change could affect other remote X server configurations, though this seems unlikely. Regression tests confirm other behaviour still works.
