Change Screen Resolution for a Ubuntu Hyper-V Virtual Machine

Just finished installed Ubuntu as a Windows 10, Hyper-V guest.  I went to modify the video settings and noticed them to be locked in place.  After some searching; Thank you Google… Found the solution that worked for me.

Steps to change screen resolution:

1. Open Terminal
   
2. Type: sudo nano /etc/default/grub
3. Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT, and add video=hyperv_fb:[the resolution you want]. The resolution I want is 1280×720. So my line ends up looking like this: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash video=hyperv_fb:1280×720″
   
4. Write the changes (Ctrl X)
5. Run: sudo update-grub
6. Reboot the virtual machine

When you return from your restart you will have the resolution you applied in the grub config.
