After upgrading to Ubuntu 16.04 from 15.10, I can no longer use my second monitor. When I attache the monitor (mini display port), the Screen Display setting app fails to launch. When booting with the monitor attached, the Unity Daemon fails. If I disable the NVidia driver and use the Intel Power Save, I can then use the display port and the Screen Display app work fine.
