Public bug reported:
The setup here is critical to understanding the problem. A laptop is
connected via HDMI to a TV monitor. Two displays are thus available to
the OS. Everything works great both in mirror display and regular
display. At the end of day, I lock the user account and the display
manager (DM) tells the monitors to blank (sleep?). When I touch the DM
and login the laptop display livens up and looks good. However, the TV
display often doesn't and I need to wake up the TV with the TV control
stick. This works OK, and the second display comes back. And all the
windows associated with that display return from sleep OK. *HOWEVER*,
all the geometry for those windows (term windows is one example) are
lost. I can see the windows in the term overview, but I cant get to them
on the second display.
