[Antonio Censi <accensi@xxxxxxxxx>]

Tested with kernel 3.11.5 from mailine.

accensi@ACC-MacBookAir:~$ uname -a
Linux ACC-MacBookAir 3.11.5-031105-generic #201310132235 SMP Mon Oct 14 02:35:52 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

It works ok.

DisplayPort is detected and there is no messages like
"[drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up"

Probably 3.11.4 would work too, as upstream DRM changes related to error message above were applied on it:
drm/i915/dp: increase i2c-over-aux retry interval on AUX DEFER

Will complete other tests (on boot, after suspend, after hibernate,
etc).

Thanks

Title:
  External display stopped working

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to 13.04 beta, my external monitor is no longer
  detected/driven. This works perfectly under 12.10, and is therefore a
  major regression impacting common use cases.

  When the Display Port/VGA adapter is plugged in dmesg reports 15 instances of:
      [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up

  Hardware: MacBook Air 2012
  Display configuration: Apple Display Port to VGA adaptor
  Ubuntu version: 13.04 beta.
