How To Make Linux Full Screen In Virtualbox

In this blog post, we will guide you through the process of making Linux full screen in VirtualBox, enhancing your virtual machine experience. VirtualBox allows you to run an operating system in an app window on your desktop that behaves like a full, separate computer. However, running the virtual machine in a smaller resolution can be quite annoying, and hence, making it full screen becomes necessary.

To make Linux full screen in VirtualBox, we will utilize guest additions, which are a set of device drivers and system applications intended to achieve closer integration between the host and guest systems.

Step 1: Update the System

First, update your system by running the following command in your Linux terminal:

sudo apt-get update
sudo apt-get upgrade

Step 2: Install Required Packages

Install the required building tools and some additional packages using the following command:

sudo apt-get install build-essential module-assistant
sudo m-a prepare

Step 3: Install Guest Additions

Next, we need to install VirtualBox Guest Additions. You can do this by clicking on Devices in the VirtualBox menu at the top of the screen, and then choosing Insert Guest Additions CD image…. This will mount a virtual CD-ROM drive with the Guest Additions installer.

Step 4: Run the Installer

Once the CD image is inserted, navigate to the CD-ROM directory in your terminal and run the installer:

cd /media/cdrom
sudo sh ./

After running the installer, it’s best to restart your VirtualBox. Once you have restarted, you should be able to switch to full screen mode by pressing the Right Ctrl + F on your keyboard.


Now you know how to make Linux full screen in VirtualBox. The steps above are quite straightforward and should solve your issue. However, if you encounter any problems, feel free to leave a comment below.
