how to find the current version of gnome

I'm using ubuntu 12.04.

I tried

$ gnome-about –gnome-version
gnome-about: command not found
$ gnome-session --version
gnome-session 3.2.1

Why I need is because my desktop environment doesn't look like though wikipedia states that the default gnome version on 12.04 is 3.4.1.

Your gnome version is 3.4.1 and is alright.

But you have to make sure at the time of logging in--that is, at the beginning of the session--that you select the "gnome" desktop environment among many. The other options may include:

• GNOME Classic [which provides a "GNOME Fallback" session]
• GNOME Classic (no effects) [which may provide an even lighter weight GNOME Fallback]
• Ubuntu [which provides Unity]
• Ubuntu 2D [which provides Unity 2D]

When you log in (when the machine boots up, or even now by closing all applications you can log out and again log in), there is a small round symbol on the right hand side of your user name on your log in dialog box. By clicking over it you can find a drop down list of options. Select GNOME.
