Ubuntu – How to permanently disable notifications about Auto capture keyboard and Mouse pointer integration for a Virtualbox VM

keyboardmousevirtualboxvirtualization

I have installed Ubuntu 16.04 on a VirtualBox VM. Now every time I boot it, I get two overlay notifications from VirtualBox:

You have the Auto capture keyboard option turned on. This will
cause the Virtual Machine to automatically capture the keyboard
every time the VM window is activated and make it unavailable to other
applications running on your host machine: when the keyboard is
captured, all keystrokes (including system ones like Alt-Tab) will be
directed to the VM. (…)

and

The Virtual Machine reports that the guest OS supports mouse pointer
integration
. This means that you do not need to capture the mouse
pointer to be able to use it in your guest OS — all mouse actions you
perform when the mouse pointer is over the Virtual Machine’s display
are directly sent to the guest OS. If the mouse is currently captured,
it will be automatically uncaptured.

These overlay notifications persist from the start of boot untill I click on them.

Can I disable them permanently?

I'm runnung VirtualBox 5.0 on Ubuntu 16.04 (amd64).

To remove the message once: click the X button.

To remove the message once and for all: click the crossed-out balloon next to the X.

To reinstate these messages, go to Settings -> User Interface -> File - Reset all warnings (this is my translation, could be slightly different).
