This solution was implemented using Ubuntu 13.10 x86_64 as the host machine.
This bug seems to be fixed using Virtual Box 4.3.8. The downloads can be obtained from the repositories published by Oracle following the installation steps provided by the documentation: https://www.virtualbox.org/wiki/Linux_Downloads After installing the 14.04 iso on the guest machine, install any updates and the packages build-essential and dkms. These are needed for Virtual Box to install itself properly as a Debian package. After installing these packages, reboot the machine. After booting the guest machine, install the guest additions iso that is packaged with the Virtual Box 4.3.8 package. This should allow for proper 3D acceleration with the Unity desktop environment. -- You received this bug notification because you are a member of DX Packages, which is subscribed to nux in Ubuntu.
