Public bug reported: This is a regression from 12.10 where this adapter worked without any problems. The effect of this bug is that you can't use MacBookAir machines and use any display device with VGA. (Bad publicity to have to boot into Mac OS X to show a presentation about how good Ubuntu is, and why you'd want to switch ...)
This bug is as similar to Bug #1222734 - the difference (as far as I can tell) is the MacBookAir version (5,1 - 5,2).
