Bug Description

On the multi-screen display when i start Einstein it changes the settings to the single display. And these settings propagate even after the application derminates.

To reproduce:
Start Einstein
Exit Einstein

What happens:
The screens are now mirrored.

What i expect to happen:
At the very least the settings should go back to normal after Einstein exits.

Changed in einstein (Ubuntu):
status: New → Confirmed

I see the same bug in Debian 9, there is a corresponding Debian bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=546671

A workaround on Debian 9 is to specify the screen to use:

export SDL_VIDEO_FULLSCREEN_HEAD=0
