Graphics Controller: Specifies the graphics adapter type used by the guest VM.
Note that you must install the Guest Additions on the guest VM to specify the VBoxSVGA or VMSVGA graphics controller.

The following options are available:
– VBoxSVGA: The default graphics controller for new VMs that use Windows 7 or later.
This graphics controller improves performance and 3D support when compared to the legacy VBoxVGA option.

– VBoxVGA: Use this graphics controller for legacy guest OSes. This is the default graphics controller for Windows versions before Windows 7 and for Oracle Solaris.

– VMSVGA: Use this graphics controller to emulate a VMware SVGA graphics device.
This is the default graphics controller for Linux guests. – None: Does not emulate a graphics adapter type.

Hallo, geht es bei dir auch um Ubuntu 18.04.3 LTS oder um ein anderes OS? Siehst du beim Starten das BIOS oder ist die Konsole dauerhaft schwarz? Grüße Daniel
