<pre>GNOME 3.22 Wayland Ubuntu 17.04
Running with internal 2560 + 1 external 4k display work fine
Arranging 2560+4K externals side-by-side and internal 2560 below:
second external monitor disconnects within 10 s
(cannot have wider than 8k pixels)
disconnects means that one or all displays go black for 1 s then behaves like
they were just plugged in
sometime it works for a while
as of late: never works
Used to be lot worse, all monitors frequently disconnecting when:
updating Wayland window
moving mouse cursor across display boundary
having Wayland window straddling a display boundary
Could become eternally cyclic when disconnecting a display placed a Wayland
(Terminal) window across a display boundary, causing yet another reset
MacBook Pro 13" 2015
Using 4.12.8
Have to use Kernel 4.11.6+ due to #99295
Used to work prior to 17.04/4.10+
