Public bug reported:

I have a dual-monitor setup (laptop + external monitor). Unplugging the
external monitor then running 'detect displays' in NVidia Settings
results in the "Disable Display Device" dialog being displayed on the
just-unplugged monitor. This is not helpful.

To reproduce:
1) Boot Ubuntu w/ an external monitor hooked up. The system comes up and drives both screens
2) Launch nvidia-settings; select "X Server Display Configuration". Note that the 2 screens are shown in in TwinView mode. The laptop's internal monitor (DFP-0 on GPU 0) is set as the primary display according to the "Make this the primary display for the X screen" checkbox in NVidia Settings
3) Unplug the external monitor
4) Press the "Detect Displays" button

At this point the nvidia-settings app appears to hang - the buttons
(including 'Quit') don't respond. The Layout widget continues to show
the external monitor as being connected. The device tree in the left
pane of NVida Settings does show the external display as being removed
from GPU 0.

5) Plug the external monitor back in. Note the "Disable Display Device"
dialog is displayed on the external monitor.

The dialog should not be displayed on the monitor that was just
unplugged. It should be displayed on the monitor that was not unplugged,
so that it is actually usable.
