I have successfully installed Ubuntu 11.10 and 12.04 on my MacBook Pro 8.1 and now I have issues with my touchpad. I am used to click the button of the pad instead of tapping it to click an item, however the touchpad does not allow me to move the cursor with one finger while having my thumb on the button on the bottom. This is extremely weird and driving me crazy - is there any way to configure Ubuntu or the driver to allow the thumb being on the pad without being recognized? (Maybe by increasing the necessary pressure on it?)
this is one of the new features of ubuntu 12.04 install it and you will be good to go!
