Is there a way to make a fullscreen on VirtualBox?

I tried many ways to make a bigger screen in VirtualBox because I do not like the small size of the guest window? Is there is a way to make it big?

Solution 1:

View -> Switch to Fullscreen Mode (or HOST+F)

Right CTRL is normally the default HOST key.

You need to install the Guest Additions to be able to adjust the guest screen geometry to the host in fullscreen mode.

Here are different instructions to install Guest Additions.

Solution 2:

You need to install the Guest Additions go to devices menu > select "install guest additions" after installation restart virtual system now select view menu and click "switch to full screen"

Solution 3:

I tried the solution provided by Mawhrin-Skel. However, it didn't work for me the first time. Then I installed virtualbox-dkms and virtualbox-guest-dkms and tried the solution again. This time it worked for me. Following are the steps that I followed

1. Click Devices -> Insert Guest Additions CD image from the menu of the VM window
2. Restart the VM

Then:

sudo apt-get install virtualbox-dkms
sudo apt-get install virtualbox-guest-dkms
sudo apt-get remove libcheese-gtk23
sudo apt-get install xserver-xorg-core
sudo apt-get install virtualbox-guest-x11

Hope this helps
