How to tell Ubuntu from Ubuntu 2D using Terminal Commands Only?

[Petro Dawg]

Hopefully this is a question with a simple answer...

I'm trying to think of a terminal command that will allow me tell if I'm logged in to Ubuntu or Ubuntu 2D.

I tried...


lsb_release -a

and


uname -a

but they appear to both return identical results in both Ubuntu and Ubuntu 2D.

Is there a simple command that has a different output depending on which environment I'm logged into?

Thanks.

Petro Dawg; Hey ...

this:


echo $DESKTOP_SESSION

output:
12.04 3D =>ubuntu3d is reported
12.04 2D =>ubuntu2d is reported



hope that helps
