Ubuntu 14.04, 15.10, and Kubuntu 16.04.1 runs correctly as a Windows 10586 Hyper-V gen2 VM on a Lenovo P50 host. Ubuntu 16.04 fails and does not. It presents the login screen and then displays failures and no desktop. Attached screenshot 1.png shows 3 VM windows and the 16.04 presenting the error dialogs. (the errors flash and only display momentarily).
