I am installing this on the Mac under Virtual Box. This snip is about Ubuntu.
The first problem is that it comes with quite a bit of crap installed and the Unity search is over zealous and too network noisy.
This might be helpful, an article about the first 10 things to do. I seem to have a problem with finding the dash plugins to stop the internet searches. This needs to be tuned.
I want to configure the software package manager to check daily.
I have installed Unity Tweaks.
I have turned the virtual desktop manager on.
I have uninstalled Ubuntu One.
