Ubuntu 20.04 Full Screen Mode Resolution in Hyper-V is very small

Solution 1:

The xrdp.service is not starting because the address already in use. There is an issue about this on github.

To solve this:

First, get the scripts from GitHub:

sudo apt-get update
sudo apt install git
git clone https://github.com/Microsoft/linux-vm-tools.git ~/linux-vm-tools
cd ~/linux-vm-tools/ubuntu/18.04/

Then, make the scripts executable and run them...

sudo chmod +x install.sh
sudo ./install.sh
sudo reboot
cd ~/linux-vm-tools/ubuntu/18.04/
sudo ./install.sh
sudo systemctl enable xrdp.service

Open /etc/xrdp/xrdp.ini for editing:

sudo gedit /etc/xrdp/xrdp.ini

add these two lines (or change them if present):

port=vsock://-1:3389
use_vsock=false

restart the service and system:

sudo xrdp restart
sudo shutdown -h 0

On Windows Powershell with Admin Privileges, run the command:

Set-VM -VMName <your_vm_name>  -EnhancedSessionTransportType HvSocket

This solution is adapted from the Microsoft Tech Community and a post on medium.com

You can use these steps:

Edit Grub
```
 sudo vi /etc/default/grub
```
to modify the resolution during boot

Modify

 GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920x1080"

Modify

 GRUB_CMDLINE_LINUX="quiet splash video=hyperv_fb:1920x1080"
