Here are more logs from the screen. Problem could be: "eDP1 and DP-2 are both trying to use pipe A"
It maybe relates to: https://bugs.freedesktop.org/show_bug.cgi?id=92916#c14 (comment 14)
Comment 3 Lionel Landwerlin 2016-02-26 11:47:13 UTC 
I uploaded a new set of patches for the tests : https://patchwork.freedesktop.org/series/2721/
It should fix the issue with multiple screens.
