I have installed Ubuntu Server 16.04 and on top of it GNOME in a VirtualBox VM. Since I updated the system, I can boot the VM, access the terminal console and log in - but when I run
startx in order to start the graphical GNOME desktop environment, I receive the following error message:

Among the updates were some kernel packages. Does anyone know how to solve this problem?
