Parrot OS 4.7 Full-Screen Issue

This is a quick easy fix. By default, it appears that Parrot OS 4.7 virtual appliance (.ova) doesn’t come with VirtualBox Guest Additions installed. Once you have booted up Parrot OS run this command to install the VirtualBox Guest Utilities. Once this is installed, you may reboot and everything should be fine.

$ sudo apt-get update
$ sudo apt-get install -y virtualbox-guest-utils virtualbox-guest-x11
$ reboot
