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

Status in udev:
  New
Status in Ubuntu:
  New

Bug description:
  On Thinkpad L540 with intel graphics:

  External monitors are not recognized in display settings when plugged
  in (into any port including VGA).

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

  A monitor plugged into the internal VGA is recognized instantly.

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

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