This bug is causing dual monitor problem for me as well. It looks like it was registered a long ago, when can I track if it gets fixed? It is quite annoying that there are two options: either use laptop's display only or use laggy open drivers...
Reproduced in: DELL INSPIRON 5749 NVIDIA GeForce 840M Kubuntu 15.10 x64 I would appreciate any advice.
