[ubuntu] Ubuntu macbook pro 9,1

Dear ubuntu's,

I have searched over dozen of pages explaining how to install ubuntu correctly, but untill now only found tutorials for other older models, and also once done I ran into problems like not seeing my desktop anymore or any icons for that matter.

I just want a clean normal install that works, yes some work is required but which adds are important and which are not.

Hope you can guide me the way or show me a tutorial that is the same to my model.
