I'm on Natty alpha 3 2.6.38-5-generic

I had click on "open new tab" in firefox, and my system, became unstable, when I clicked all my screen froze, and my screen became totaly black, my computer screen wrote that he didn't found signal. And everything is back, but when I clicked on a other things, like a windows, it did again. Finally i'de click on the button "reset" of my computer, and reboot. For the moment this bug didn't back.

Sorry for my english, I'm french.
