Right, after a lot of unsuccessful googling I came across a solution to the new Linux Ubuntu’s new UI Unity not working in WMware Fusion.
The reason Unity does not work is something to do with the ‘accelerated hardware/graphics’ not being compatible at this moment. And, finally there is a solution to this.
Unity is a 3D UI hence the extra acceleration needed. So.. we can install a 2D version, which from what i understand is completely the same (just without all the whistles and bangs).
First we need to add the 2D repository to our Ubuntu’s software manager. In terminal type:
sudo add-apt-repository ppa:unity-2d-team/unity-2d-daily
Then we need to update Ubuntu’s app cache:
sudo apt-get update
And finally install the new 2D version of Unity:
sudo apt-get install unity-2d-default-settings
Then restart and choose Unity 2D from the Session options at the bottom right when you next login.
