Hi All, This morning I recieved a Matrix TripleHead2Go, which officially doesn't support Linux, but guessed that it should just require a bit of tweaking to my /etc/X11/xorg.conf to get it to use the right modelines so bought it anyway ;-)
So to help get the modelines right I did a google for modeline calculator and found several to choose from, from the results from these I edited my /etc/X11/xorg.conf and hey presto I'm now running a single linux dekstop at 3840x1024 across three screens from just one graphics card. I've posted my xorg.conf on the KnowledgeBase section of the wiki just in case you need a working configuration file to crib: http://openscenegraph.org/osgwiki/pmwiki.php/KnowledgeBase/TripleHead2Go Static Image quality isn't quite as good due to slightly blurring. However, despite the high resolution performance with a single 7800GT is pretty good, keeping a solid 60Hz for most scenes, and the screens are all pretty well sync so real-time quality is actually pretty sweet. You can't fault have surround graphics for a desktop ;-) The next things for me to experiment with are trying to run 6 outputs from two graphics cards each with its own TripleHead2Go. Matrox say its only designed for one TripleHead2Go per machine, but I can't see a reason why it shouldn't work just fine. I presume this type of usage is just a bit beyond Matrox's core market, but hey its just too tempting to not try ;-) The other thing to try is two cards in SLI driving a single TripleHead2Go, haven't tried SLI under Linux yet so this is another bridge to cross... Then if this works then it'll be four cards in SLI pairs driving two TripleHeadGo's ;-) Robert. _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
