I do, I use it as my one and only controller and have on the past three distros I've used with no issue. I quite literally used it last night in Steam, so I bet some setting got changed within Steam somehow.

Edit: I see in your other comments that you're using your gamepad to control the mouse cursor. That's definitely not a default behavior, I think you should have been more clear in your post that you're using the gamepad for not actual gamepad things.
