Michael Paddon, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily kernel folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.12-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

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.
