Bug Description

EDID does not change when hotplugging a monitor

It appears Mir only gets the EDID right if the monitor was plugged in before the server started.

If you change monitors, then Mir continues to report the old monitor's EDID. And similarly if the server started before the monitor was plugged in, Mir always reports no EDID for it.

Other attributes like physical size appear to change correctly when hotplugging. Only the EDID is wrong.
