Hi all,
I am using Ubuntu 12.10 with GNOME 3.6. My problem is that, my keyboard doesnot work in Gnome "Activities" window (The one i get when i click superkey or move my mouse to top-left corner)... I cannot type anything to the search field. Nothing i type is entered to the search field.

The same is the problem when I have to type passwords where authentication is required (like opening synaptic package manager). I cannot enter my password. Nothing i type is shown in the password field.

Keyboard works in other places like Nautilus, any softwares etc. I think problem only with gnome shell components

What should I do? Please help..
