Title:
  External display stopped working on MacBook Air

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.
