Hyper-V Fullscreen Mode – Enable for Ubuntu 14.04 on Windows 10

Since this question was asked (re ~ Ubuntu 15.04) things have progressed significantly with regards to Hyper-V & Ubuntu 18.04.1 with regards to ‘Enhanced Session Mode’.

There are two approaches currently:

A. New System ~~ Optimized Ubuntu Desktop images available in Microsoft Hyper-V gallery

B. Existing System ~~ manually configure xRDP to support ‘Enhanced Session Mode’

Here are the details:

Option A)

1. In Hyper-V, on your server & select [Quick Create]
2. In the [Create Virtual Machine] dialog, select [Ubuntu 18.04.1 LTS] && then [Create Virtual Machine]
3. Then complete the standard Ubuntu installation options
4. ‘Enhanced Session Mode’ will prompt you to setup screen resolution, local resources, etc.
5. Note/Caution ~ if you have problems using drives, then you may want to de-select the [Printers]

Here are the links to where I sourced the information:

○ Optimised Ubuntu Desktop images available in Microsoft Hyper-V gallery

○ Run Ubuntu virtual machines made even easier with Hyper-V Quick Create

Option B)

1. Modify Ubuntu 18.04 to use xrdp

   1.1 Get the scripts from GitHub

   sudo apt-get update
   sudo add-apt-repository ppa:git-core/ppa
   sudo apt update; sudo apt install git
   git clone https://github.com/jterry75/xrdp-init.git ~/xrdp-init
   

   1.2 Make the scripts executable and run them...

   cd ~/xrdp-init/ubuntu/18.04/
   sudo chmod +x install.sh
   sudo ./install.sh
   reboot
   

   1.3 <After Reboot> Run script again to finish setting up VM

   cd ~/xrdp-init/ubuntu/18.04/
   sudo ./install.sh
   

2. Shutdown Ubuntu VM

3. Register Ubuntu Session ~ run this command on host PC using powershell with admin rights:

   Set-VM -VMName YourUbuntuVMNameHere -EnhancedSessionTransportType HvSocket
   

4. Restart VM

5. Connect/Login to XRDP from Hyper-V (note ~ enter username - must be lowercase)

6. Note/Caution ~ if you have problems using drives, then you may want to de-select the [Printers]

This is conceptual, not step by step, but it should explain enough to help you figure out what you need to do. The Hyper-V switch that the VM uses needs to be either External or Internal and not Private. Keep in mind that an External switch will look like a LAN connection to the VM, not a wireless connection even if on the real hardware it is associated with a wireless adapter. Also, an External switch may not work with all wireless routers as some recognise that a DHCP request coming from your VM is really coming from the same machine and won't give it an address.

The way around this (the wireless router sounds like the issue from your description) is to set the Hyper-V switch for your VM to be Internal and then use ICS (Internet Connection Sharing) on the hardware's real wireless adapter, sharing with the Hyper-V switch. ICS is on a tab when you open the properties on the adapter that just says "Sharing". It makes your adapter behave like it is a NAT router to the other adapters in your machine. It responds to the VM's DHCP request and allows the VM to connect to it so to speak.
