Bug Description
I just dist-upgraded my Zesty machine and two things broke related to sleeping the displays. I have a 34" wide panel on the left and a 20" high resolution Dell on the right.
Everything works fine until the displays sleep, say after a lockscreen has started. First, the right screen never wakes from sleep; even though the lights on the front are green (indicating an active display), once the right display has slept, it never wakes back up even after a login.
Second, and probably related: all the windows that were on the right display are now shifted over to the left and full-screened.
This has all worked for a long time, but something in the recent stable updates has broken this, so it's a pretty serious regression. Nothing short of a reboot returns the dual screens to full functionality.

FWIW, booting 4.10.0-20 hangs on boot so that's not a viable option.
Also, setting Brightness& Lock->Turn screen off when inactive for: Never
does not prevent Ubuntu from sleeping the displays (after progressive dimming) and thus causing the problem.
