Ubuntu Linux add VirtualBox Guest Additions Step #1: Check logs of VirtualBox for errors If not you can follow how to install them in this article: It's good idea to ensure that guest additions are installed for this Virtual Machine. Some of them are related to dual monitor setup, others to incorrect graphic settings. So after short investigation of the problem I found several possible problems and solution which I decided to wrap up in article. But again - successful install followed by black screen after boot of the machine. I decided to install the older working version and see if the problem is solved. No matter of changing or resizing the window. I created new VM for the latest Linux Mint 19.3 which was installed successfully but after reboot the screen was black.


I have VirtualBox with two working virtual machines(VM): Windows and Linux Mint.
