Unity-2d on Trusty 14.04 [duplicate]
I have a laptop with a graphics card (gma500) which has a framebuffer driver only, resulting in the same horrible framerates/performance.
The best solution for me is running Lubuntu. This is Ubuntu including the same software repository, but with a light weight desktop manager called LXDE. It is graphically not as slick, but muuuuch faster on light hardware or on systems with some issues. I even recommend it on more modern computers, if you prefer speed above presentation.
If you like the idea, you can give Lubuntu a try by downloading and running it live from a CD or USB-key.
Does this help you?
Starting from Ubuntu 12.10, Unity-2D is no longer in the repository. You should install the Xfce or Lxde desktop environment maybe, or download Ubuntu 12.04
