Hyper-v ERROR - Video remoting was disconnected unexpectedly


I have enabled Hyper-V in my Windows 10 Pro (v.1809) and installed Ubuntu-v18.04.2-64bit Desktop image. In Hyper-V Manager, I have been getting this error when connecting to the virtual machine - ERROR: Video remoting was disconnected unexpectedly.


But from this screen I think it's started successfully - Ubuntu 18.04.2 running screen.


I have tried many solutions and none of them work for me:

  1. Enable RemoteFX from https://www.eightforums.com/threads/hyper-v-new-vm-doesnt-start.49758/
  2. Disable enhanced session mode from https://answers.microsoft.com/en-us/windows/forum/windows_10-other_settings/windows-10-client-hyper-v-enchanced-session-keeps/adb7ba2b-9662-46d3-8397-bda905aa69f0

I try to start all Hyper-V related services but only the following ones can be started: HV Host Service, Host Computer Service, Virtual Machine Management. The running Hyper-v related services

I also find this error showing up when connection failed in Event Viewer > Hyper-V-VMMS log - The Hyper-V Virtual Machine Management service encountered an unexpected error: Unspecified error (0x80004005).

I have the exact same problem. For now I solved by disabling the enhanced session mode in the Hyper-V configuration. But different from you I disabled in the USER section and not in the SERVER section and works for me. I hope this can help

I had the same problem and I could use the machine with the enhanced session mode turned off, but this gives the limited usability.

The problem was that I set up the Ubuntu machine to log me in automatically. When I set it up to "Require password", I can use the enhanced mode.
