Confused about Gnome (Gnome Shell)

[mbott]

I have two systems with Ubuntu 14.04.1 installed. My primary is a Asus desktop with 16GB memory and an i5 processor. Earlier this week, I purchased a Dell Inspiron 15 laptop which is a dual core Pentium with 4GB memory. Everything works great on both systems, however on the laptop when I load the Unity Tweak Tool, I get the message that the Gnome Shell is not running. The program is different visually between the two.

This is the only difference that I have detected between the two and I'm curious as to why? Available memory maybe?

Thanks!

The look of gnome-shell versus unity is one aspect where they differ.
Another is the underlying window manager each uses.
Unity uses compiz and Gnome-Shell uses mutter(metacity)
They're completely different desktop setups.

I'm also confused.
Are you sure you did not install gnome tweak tool?
Unity tweak tool has never cared, nor would it, that gnome-shell is not running. As far as i have ever seen.
But gnome tweak tool would...

Oops! that's exactly what I did! All fixed now. Not sure how I missed that, but I did.

Thanks!
