I found the solution of the second problem. That was very simple... Ubuntu crashed days before my try, and I did not see that it disabled my graphic card drivers. So, i enabled them, and now I can launch games properly. That runs with sound and video, perfect.
But the first problem remains : I cannot find how to make Dolphin recognize my gamepad. Anyone has an idea ?
