Hello folks,Several months ago I activated Unity 2d in my Trisquel 6 system. I followed the instructions given here
https://trisquel.info/en/wiki/how-install-unity-desktop-environment-and-create-session-entry-trisquel-70
Now I want to go back to "regular" Unity with all the 3d stuff. But I don't see this option in my log-in screen. The only Unity-related entry I have is "Ubuntu2d".
How do you reactivate Unity?
