Dual monitor layout is lost after external display disconnect

[robled]

I've got a Lenovo ThinkPad T430s laptop. I frequently connect it to external monitors. Upon disconnecting and reconnecting, the dual monitor layout is not restored and must be manually re-configured each time. This is reproducible each time I reconnect to a previously configured external monitor. This may be a regression from Ubuntu 13.10 since I recall it working fine on that release.

I'm attaching some screenshots, xrandr output, and my monitors.xml file.

Dual monitor settings are lost on every power cycle of this ASUS motherboard system.

It's a usability issue that doesn't limit the functionality of a core package.
