Ubuntu Netbook Edition

[Jeffrey Needle]

My first post here.  Please be patient with me.

I'm using the latest incarnation of Ubuntu (10.10).  I quite like the 
Netbook edition -- its interface is so friendly and comfortable for me.

When I start Ubuntu, I get the sign-in screen, and after pressing <enter> 
to get to my password, I'm given a choice of interfaces at the bottom of 
the screen.  One of the choices is the Netbook edition.  I choose it, 
start Linux.  What I get are a series of icons on the left side of the 
screen, and then, after a few moments, the familiar drop-down menus at 
the top of the screen.  When I move the cursor to any of the icons, the 
screen goes blank and refreshes.  Nothing brings up any of my choices.

Oddly, when I choose Netbook 2D, it works fairly well.  I get the 
familiar interface, albeit somewhat larger fonts.

Is there something I can do to get the regular Netbook interface to work 
correctly, other than reinstalling the whole system?

Thanks.
