Yes this is fixed upstream, Yay!
Given that vivid is end of life, i think you can close this, but leave it up to
you.
In any case: Thanks for guiding me through this!

Title:
[Regression] Thinkpad dock: External monitors not recognized after
15.04 upgrade
Status in linux package in Ubuntu:
Confirmed
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.
