Ubuntu 11.10 is falling back to Unity 2D. How to get back to Unity 3D?
- by marcioAlmada
It happened some minutes ago when I plugged my secondary monitor and my graphical interface simply crashed. So I had to restart my session. Since the crash Ubuntu insists to use Unity2D fall back instead of the default one. I used to plug the secondary monitor everyday when at home and nothing bad happened before.
This 2D version of the GUI is ugly and has a lot of problems. How can I go back to Unity 3D GUI?
update
It seems somehow I lost my opengl support (driver issues).
$ glxinfo

And:

How can I revert things and go back to the right driver?
