In Ubuntu Hardy, there was an option where one could configure the drivers for their video card via a button in the display preferences dialog. Now that I've installed Jaunty, that option seems to be missing. Does anyone know where to find that option? I want to find that because my video card (an ATI Radeon) is a little screwy; Super Tux Kart crashed after about 20 seconds running it, so I'm having some 3D rendering problems.
