For those using motherboards with the AMD RS690 IGP, the DDIA Digital Block is now supported by the RadeonHD (xf86-video-radeonhd) driver. DDIA is the second digital block on this IGP that came as a mystery to both AMD and the RadeonHD developers as they believed no motherboard vendors were actually using this block. With this latest code addition, two displays should now work with the RS690 in an independent fashion. Check out the latest xf86-video-radeonhd git code if you're one of these RS690 owners. A few other code fixes were also committed this afternoon.
