I'm testing Natty on a dedicated test machine. I've not used nor seen Unity before this except in screenshots, but I understand that one of the main elements of the Unity UI is a dock. Well, for some reason there is no dock on this machine. The Global Menu is there, and the Ubuntu Button and such like, so I'm satisfied that Unity is running (I also verified this by trying to run it from a terminal.)
I'd appreciate any ideas as to why the dock never showed up and how I can install or activate it manually.
Here's a screenshot with Unity desktop ("Ubuntu" option in login menu):
Here's a screenshot with GNOME desktop ("Ubuntu classic" option in login menu):
As you can see, it's somewhat difficult to tell by looking which one is running. IMO since both desktops ship with Natty and neither one of them is 100% bug-free, there ought to be an easy way to tell them apart. As it is, they can be distinguished by the slightly different appearance of the upper banner and lower banner. For example, in "Ubuntu Classic" the Ubuntu Button at upper-left corner of the screen is in larger and colored orange and yellow.
