Improving Ubuntu 12.10 Performance

Unity 2D was retired in Ubuntu 12.10. The new fallback desktop for low spec machines is Unity 3D with software rendering (the LLVM pipe). I’m do not know why anyone thought this would be a good idea as old machines without 3D capable video cards are somewhat unlikely to be powerful enough to perform 3D rendering on the CPU, but that’s for another day.

In order to make Ubuntu 12.10 work well in a VM, you need to ensure that the guest additions are installed and 3D rendering is enabled. This is trivial in VirtualBox, but there is a snag. You have to manually load the VirtualBox video driver. To do this, add `vboxvideo` without the quotes to /etc/modules. Restart the machine and everything feels faster.
