OpenLaptop - Unity-2D is not part of the future window manger of Ubuntu. Ubuntu 12.10 "Quantal Quetzal" and later only have Unity-3D, which uses the LLVMpipe software driver if the GPU is not capable of running Unity-3D.
That still leaves over 4 years of Unity-2D on Ubuntu 12.04 "Precise Pangolin" though.
