I think it's fixed. 
Seems to work now.

I could not determine that.

Lenovo W541 laptop on dock station, ext monitor is Samsung connected by
DP port on dock.

Using Intel video

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core
Processor Integrated Graphics Controller (rev 06)

01:00.0 VGA compatible controller: NVIDIA Corporation GK106GLM [Quadro
K2100M] (rev a1)

Not using extensions.

Thanks for the reboot advice. Didn't have a chance to try it 'this'

Lenovo machines can be finicky with Linux, because the hardware depends
a lot on custom MS Windows code, written by Lenovo, to function. So,
this report may have  a very narrow scope. I cannot determine what
changed to make 'ext display only' suddenly work.
