I've gotten the top monitors configured on the 6450, and I can actually pull out the 5770 and run on just the 6450 just fine. I've got the bottom two plus right monitors working on the 5770 just fine. However, when I boot with the above xorg.conf, I cannot get the monitors on both cards onto the same screen - I cannot get one continous display. From what I can tell, the top two monitors (on the 6450) are coming up on a seperate Xserver. I believe this *should* do this, I cannot see how it could not, but it sure is not. I'm also still somewhat new to Xorg things - I'm good with moving my monitors, changing stuff around, etc. Once I get this sorted, I'll probably move the sections down for the different monitors to the individual files in /usr/share/xorg.conf.d/ but first I have to understand what I'm doing wrong with this. Mostly, I think I'm just stuck, possibly with a case of the stupid, and need some help.
Any help/insight is appreciated.
