Comment 18 for bug 382056

I recently migrated from an old System 76 desktop machine running 16.04 with two heads and old monitors to a new System 76 desktop system running 16.04 and a pair of new Dell monitors. The biggest change is that the monitors are now hooked up via HDMI. As soon as I made this change, trouble started. Every morning when I unlock the screens, all of my windows are now living on the left screen for workspace one. So the windows move off monitor two, and they move off other workspaces to all congregate on one monitor and one workspace. I have never experienced this before my system change - which was all just hardware.
