12.04: after installing Gnome-shell, Unity 3D disapeared.

[Ghil]

Let me expand:

I installed Gnome-shell to test it, and weirdly it was really really slow (like 3 minutes to open Nautilus slow) so I switched back to Unity 3D, but while the desktop boots, the dash and top bar are not showing at all. Unity 2D still functions fine. What can I do to get back Unity?

Have you tried?

unity --reset

[Ghil]

so far, worked like a charm, thank you!
