[vtkusers] Oracle VM VirtualBox and VTK

[Pat Marion]

Hi Andrew,

I'm not sure if this will help at all, but I'd try switching the desktop
environment on your Ubuntu 12.04 install.  By default, Ubuntu uses a 3D
accelerated desktop environment named Unity.  You could install gnome
classic:

    sudo apt-get install gnome-panel

and then log out and at the log in screen select Gnome Classic (No effects).
