crash

My specs: Ubuntu 12.04.1 LTS, Gnome3, Dell Studio laptop

This is not happening all the time, but only sometimes .. totally randomly.

When I'm in the middle of some work something totally weird happens. Keyboard suddenly stops working. I can't type, no matter which key I press nothing happens. I can't press Alt+Tab, I can't press Alt+F4, Alt+F2... nothing. Activities button is dead.

Also right click does not work...and something even more annoying. I can click on the 'menu' in the top right corner(the menu pops up), but clicking on 'power-off' or 'suspend' option doesn't do anything.

The only little thing I can do is:
Close the lid of my laptop so it goes to sleep. Than wake it up again. And than it's ok. Everything works. So I guess restarting (or refreshing) gnome-shell fixes the problem.

Sorry if the title of this question is odd... I don't know how to properly describe this.
