I am using Ubuntu 11.4 alpha3 for testing. I see that some applications have been removed like Appearance where we play with theme preferences.
How can I change themes in Unity? What interface do I use?
During the upgrade process my default Ambiance theme got corrupted.
Window decoration are fine but GUI widget (e.g boxes, button, scrollbars) now have Windows9xish look.
How can I restore my default Ambiance theme?
