aexl, while Vivid is EOL as per https://wiki.ubuntu.com/Releases, the
release you would be upgrading to isn't.

Hence, to see if this is already resolved in Ubuntu, could you please
upgrade to either Wily or Xenial, and advise if this is still
reproducible?

Title:
  [Regression] Thinkpad dock: External monitors not recognized after
  15.04 upgrade

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  External monitors are not recognized in display settings when plugged
  into any dock port.

  They *are* recognized after a reboot (not after logout).
  After plugging out and the in again they are not recognized.

  A monitor plugged in and out of the non-dock VGA is recognized instantly.
  After plugging in or out of the non-dock VGA, monitors plugged to dock ports are recognized (which serves as a crazy workaround for me now)
  (update: this works sometimes, sometimes not).

  Everything used to work with 14.10, but stopped with 15.04.

  A recent test with 1510 live CD did not fix this.
