Title:
  Dual Display not working on Mac Mini

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  On a fresh install of 13.10, the second display fails to detect /
  initialise after X has started.

  Installing a mainline kernel (It was an Intel drm-next nightly)
  resolved the issue, and the second display detects and is useable as
  expected.  For interest that version was: 3.12.0-997.201310110505
