  • You have installed your GPU drivers and the VirtualBox extension drivers I presume?

  • @Ramhound No, I am not installed any GPU driver and I installed only virtual box guest addition Oct 12 '16 at 13:41
  • Have a look at installing virtual box tools. It is a virtual disk you can insert into the OS and run. Just like VMtools in VMWare. Oct 12 '16 at 13:49
