One additional point. When I installed beowulf on the box with the GT1030 card, the display was fine. It was only when I upgraded to chimaera that the problem started. Don't know if firmware-misc-nonfree is installed by default in beowulf and then removed by the chimaera upgrade - at some point, I'll try this.
