Fine. I have an old laptop about 7 years old and it sucks with Windows XP. So, I decided to give Ubuntu 12.04 a try. Hey. It's fast, I mean with Gnome classic. I can tell that my machine does not have very good support for opengl. My monitor's refresh rate is 59hz, but running glxgears I found that it only runs about 30fps. That is pretty slow. Note: It is quite unstable too. Last time it runs about 30fps and now about 58fps. Strange. But in anyway, unity does not work well on my desktop. It has been the prettiest desktop I have ever used. Too bad it needs opengl, compiz, and more to work well. I am very positive that my laptop with only 1.6 ghz of cpu power cannot run unity smoothly. Any help? I love unity very much. Compiz slows down thing a lot. If I can use metacity to replace compiz in unity, it will be perfect!
