Ubuntu : Increasing screen resolution in VM

Quick tip for boosting resolution in a Ubuntu VM in HyperV

from terminal

sudo gedit /etc/default/grub

Edit or add the the assignment to RUB_CMDLINE_LINUX_DEFAULT

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

I chose 1920×1080 as this is the current maximum that the Hyper-V machine connection will support and it is less than what my monitor supports, change this to a value that makes sense for you.

After saving run:

sudo update-grub

And then reboot your virtual machine
