Displays Icon missing in Menu Bar
I noticed I no longer have a displays menu bar icon. Previously, I could click it and I could Detect Displays, Mirror/Extend and change resolution. This is gone! I've opened a case and I'm informed that "it's been removed." Well, it was removed; AFTER I installed. I clearly had the menu bar icon until my first reboot. Afterwards, it's not come back -- and I'm not too happy about that.
Anyone have any ideas? I'm going to look like a jack hole having to go through System Preferences in the middle of a presentation... talk about awkward!
NOTE: This is not a question about AirPlay. I have a mid-2010 MBP with a 2.66GHz i7 and I'm already upset that it's "too old".
