Bug Description
I switch the power of a connected monitor on and off, the state does not get detected.
When I switch the external monitor off, the system continues to "think" there are two monitors connected. Sometimes it helps to push the button "detect monitors" in the display setiings, or to hit the hardware button that toggles trough the display states (internal-only, mirror screens, external-only, extended screen) , on my machine it's the Fn-F5 key. But sometimes this does not help at all. Even worse, when I put the laptop in the docking-station with the external-monitor powered off, and the cold-boot the laptop, X "thinks" that the external monitor were powered on. As I have a laptop and two docking-stations, one at home the other at work, with two different external monitors connected I could see a really strange effect. Even with the monitor powered off I can see the correct monitor information in the display settings dialog, so some how the information is read from the powerless monitor. If connected and turned on, the displays otherwise work normally, no screen corruption of any kind. Just the state of the monitors is not correctly detected. On Quantal using precisely the same hardware it worked as expected. On external monitor on/off or dock/undock the display settings adjusted themselves to the new situation without any manual interaction. I verified this behavior also with a live USB Stick of raring-beta2.
It just worked with all Ubuntu Versions from Karmic up to Quantal, and now using Raring it does no longer work.
