title: Hyper-V W10 (Host) Ubuntu 18.04 (Guest): Why does enhanced session mode not work?
body: <p>I have installed Ubuntu 18.04 as a guest system on a Windows 10 host system using Hyper-V and I want to use the guest system in full-screen mode. To resize the screen as far as I have learned I need to run the guest system in enhanced session mode.</p>
  
  <p>If I am connecting to the guest system it neither lets me choose the screen size nor activate the Enhanced Session Mode.</p>
  
  <p>Enhanced Session Mode (User) and Enhanced Session Mode Policy (Server) are activated under the Hyper-V Settings.</p>
  
  <p>I have also tried to deactivate the RemoteFX setting -> no changes</p>
  
  <p>Guest services are activated -> no changes</p>
  
  <p>As far as I have learned Ubuntu 18.04 LTS should already support the enhanced session mode.</p>
