I have an Ubuntu Desktop 10.04 machine running smoothly.
I downloaded the Ubuntu Unity Netbook Edition just to try out the new UI.
And that thing runs very slow on my machine. Each click responds after 30 seconds.
Now if I restart the laptop, it logs on straight into Unity.
I want to know about some key-combination that would allow me to select the desktop environment before logon, so that I can log in into gnome again.
