    Setup Hyper-V enhanced session for Ubuntu 20

I couldn't find instructions that were 100% complete, so I put this together.
These instructions worked fine for me.  Follow each step carefully.
Download Ubuntu 20 desktop

DO NOT create the VM by choosing Quick Create in Hyper-V Manager. Follow these instructions exactly.
Download Ubuntu Desktop 20.04 LTS from here - later 20.xx versions will likely work as well.
Direct link as of this writing is here.
Set up Hyper-V VM

New > Virtual Machine

Use all defaults aside from:

Name: Ubuntu 20.04 LTS
Generation: 2
Startup memory: 4096
Connection: Default Switch
Install from bootable image file: (use iso downloaded above)
OK

Set Ubuntu compatible security template for Secure Boot


Settings > Security
Change Template to "Microsoft UEFI Certificate Authority"
OK

Start VM


Connect, Start

Install Ubuntu in VM

Use all defaults.
Do not choose "Log in Automatically"
Install and run linux-vm-tool script

sudo apt-get update

sudo apt-get install --yes git

git clone https://github.com/Hinara/linux-vm-tools.git

cd linux-vm-tools/ubuntu/20.04

chmod +x ./install.sh

sudo ./install.sh

sudo shutdown -r now
For reference, the contents of the install.sh script (as of commit 19ae5b9) is:
#!/bin/bash

#
# This script is for Ubuntu 20.04 Focal Fossa to download and install XRDP+XORGXRDP via
# source.
#
# Major thanks to: http://c-nergy.be/blog/?p=11336 for the tips.

echo "Install is complete."
echo "Reboot your machine to begin using XRDP."
Start VM (again!)


Connect, Start

Run the script again

Yes, you must runt the script again after rebooting. This is a step that many online instructions missed.
Note: This step takes a while to complete.
cd linux-vm-tools/ubuntu/20.04

sudo ./install.sh

sudo shutdown -h now
Set Hyper-V transport type

In PowerShell, run the following:
(note that if you named your VM something different, replace the VMName parameter accordingly.  Use Get-VM to see the name of all VMs)
Set-VM -VMName 'Ubuntu 20.04 LTS' -EnhancedSessionTransportType HvSocket
start and connect to the VM.  You should now see a prompt for resolution when the VM starts up.
You now have enabled enhanced session, which allows for copy and paste between host and VM etc.
