GNOME Bugzilla – Bug 588000
display icon does not track monitor on/off status

When I turn off a monitor in g-d-p, it turns black there, and the config options for it become unavailable. But the display status icon doesn't pick that up, it still shows the same color for the label and offers to rotate the monitor.
The tray icon for displays is gone in GNOME 3.
