I don't have xf86-video-nouveau, I have xorg-x11-drv-nouveau.x86_64 1:0.0.16-14.20101010git8c8f15c.fc14 -- Paul -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
