[Bug 1239074] Re: [MacBookAir5, 2] mini DP-to-VGA adapter not recognized

 

Next attempt for me is to find a newer Ubuntu built kernel that I can
install on my base installation (13.04). (This bug was reported from
running __LiveMediaBuild: Ubuntu 13.10 "Saucy Salamander" - Beta
amd64+mac (20131011.1)__, booted from a USB stick.)

Title:
  [MacBookAir5,2] mini DP-to-VGA adapter not recognized

Status in “linux” package in Ubuntu:
  New

Bug description:
  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).
