The release notes for the new 9.6 version of AMD's fglrx driver states that MultiView now works with non FireGL (ie, consumer level) cards:
MultiView for Consumer users
Allows users to render applications using multiple GPU confi
Enables Xinerama in single or multiple configurations up
Supported on any combination of the ATI RadeonTM HD
Series and ATI RadeonTM 2000 Series of graphics cards
OK. Before 9.6, MultiView was supposed to work only with the FireGL cards series (unless one try some kind of workaround such as changing the card's PCI ID http://www.phoronix.com/scan.php?pag...ultiview&num=1 ). My question: Anyone here has successfully configured and is now using MultiView with non FireGL cards? I tried using MultiView ( I have two HD 4850 and three monitors), but I had no joy yet. First card works fine, connected to two monitors (Big Desktop), but the second card (connected to the third monitor) would not display anything and it's being reported as "disabled adapter" in AMDCCLE. Another problem is that I can't control second card's fan ( aticonfig --pplib-cmd 'set fanspeed 1 80' fails while aticonfig --pplib-cmd 'set fanspeed 0 80' just works) neither I can read second card's temperature. This is bad since if I can't adjust the second card fan speed things become really hot here. So, again: Anyone here has successfully configured and is now using MultiView with non FireGL cards?
Thanks in advance!
 Just for your information: Tried Crossfire and it worked like a breeze. It means that the drivers can detect booth cards.
