X11 error on current install

I just installed current and cannot get X11 to work. On the box running 15.0 everything was fine. I've been trying to sort this out and even reinstalled all the slackware64/x packages. Perhaps someone can give me a heads up. here's output from /var/log/Xorg.0.log after my last attempt with startx.Code:[ 4653.606] (II) modesetting: Driver for Modesetting Kernel Drivers: kms
