Unity Compatibility Problems

[Graham Stacy]

I have an Acer notebook with Ubuntu 11.04 on it, both Unity and Gnome work fine on it but when I've tried to install 11.04 on some of my desktops (mainly HPs) I've consistently received a message saying Unity will not function and I have to use Ubuntu Classic. Does anybody know how to get Unity to work on any Linux compatible desktops.
