Probably need to see your xorg.conf file. I suspect it comes down to how the two GPUs are identified there, and how the server layout is done. One heads up though about the directions you're going. It might matter. It might not. In my case I have a GTX465 as my main card driving two monitors, and then an 8400 GS driving the 3rd monitor. OpenGL doesn't work at all on the 3rd monitor. I think the way that stuff works is that it on;y works on the first card, with a possible exception being that if you use two identical cards (which neither you or I seem to be doing) then _maybe_ it will work on both. Anyway, as I know nothing about your Blender stuff, if it requires OpenGL you might be in for some additional work to get past this issue. I haven't figured it out here but it hasn't been high priority. I mostly just use the 3rd monitor for a NetFlix VM. Good luck, Mark
