Public bug reported:

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.
