I installed Ubuntu 13.04 on a VirtualBox on Windows 7 host. The problem is that the UI lags a lot. I already installed Guest Additions and etc and enabled 3D acceleration, though it made things faster it's still not running smooth. I already have Ubuntu installed on this machine as dual-boot so I have an example for how smooth the system should run.

Is there some configuration that should run Ubuntu smoothly?

Here are some specs:

Host machine:

  • Windows 7 64 bit
  • 4GB RAM
  • Nvidia 9600GT
  • QuadCore Q8300 2.50GHz

Guest machine:

  • Ubuntu 13.04 64bit
  • 1GB RAM
  • 2 Processor cores
  • 8 GB Space
  • 3D accelartion enabled

Please define "running smoothly" Do you have graphical problems, glitches, short term lock-ups, heavy disk access? – Tog Aug 11 '13 at 20:25

According to this answer on askubuntu, it appears that from Ubuntu 12.10 on, Unity 2D is no longer available. It includes a detailed guide on enabling 3D acceleration that should solve your problem.
