Have you heard of Guest Additions? Anyone who virtualizes a Linux distribution using Virtualbox easily realizes that not everything works the best. Either it is the graphics that was not detected, or the monitor definition is not the best, there is difficulty in interacting between the native system and the virtualized system, etc.

To solve such problems we can install Guest Additions. Learn how to install on Ubuntu 20.04 LTS.

What is Guest Additons?

Basically Guest Additions is a set of drivers that allow:

  • Better graphics card performance (since the graphics card installed inside the machine is usually a generic one)
  • Possibility of changing the monitor definition
  • Easy file sharing between the virtual machine and the native machine (Share Folders)
  • The mouse starts to work transparently in the native system and in the virtualized system, that is, there is no need for the CTRL (right) to “take out” the mouse inside the OS
  • …etc

Once installed, restart the machine and check the differences. With Guest Aditions the communication between the native and virtualized operating system becomes transparent to the user. By the way, don't forget that you also have support for copying information to and from the virtual machine. To do this, simply activate Share Clipboard and Drag n’Drop, in Devices, in VirtualBox. Try it and if you have doubts leave it in the comments.
