Bug Description
Running up-to-date Saucy.
Just recently (within the last couple of days) my Asus Zenbook lost the ability to support two displays.
If I boot with an external display (via mini-vga port) it will work, but the internal panel will not. If I boot without the external display, the internal panel works fine, but hot-plugging the external panel does nothing.
If I check System Settings / Displays using the external monitor, I only see my external monitor, although Displays reports it as "Built-in Display".

It's interesting, I used to suffer from LP 946311 on the same hardware. The result of that bug was that I couldn't turn on the laptop with a monitor plugged in, but hot-plugging later worked fine. Since sometime in the raring cycle (iirc) that problem was solved. It's been perfect up until just recently.
