Unable to display Ubuntu 24 Virtual Machine full screen using VirtualBox

[mano9]

Hello,
I installed Ubuntu 24 on Oracle VirtualBox. Ubuntu VM launches well but I am not able to switch to the full screen mode.
Thanks for support.

I don't use Virtualbox any more having moved to KVM/QEMU but we need more information from you to help us.

What version of VBox did you install and what is the host OS?
Have you installed the Guest Additions in your Ubuntu guest? It is needed I think to be able to use full-screen, though that may be my memory playing tricks on me. However, the GA are very worthwhile having for many other things making the VM run much better so I recommend that you install it.
