10.6.3 causes rotation to be broken

pdimarzio · 04-06-2010, 02:40 PM

In my two-monitor config the horizontal screen is driven by Apple's mini/DVI adapter and the vertical is (well, was) driven by an IOGEAR USB/DVI adapter using the DisplayLink driver. I've had to turn the DisplayLink screen horizontal because of this bug (the driver still works with no rotation).

Just out of curiosity though I tried rotating the Apple-driven screen and it worked like a champ. I can't really use this setup though because it seems like the screen driven off the mini port will always be the primary, which I don't want vertical, but I found it interesting that the OS can still do a 90 or 270 rotation but the DL driver cannot.
