I was hoping that someone might have a suggestion for the following problem. I am faced with an admittedly bizarre workstation setup that I have to work around:
- onboard HD3300 AM graphics
- PCIe FireGL v5600 card
- PCIe FireGL v8600 card
These are driving a total of 4 displays, and all the cards have to be used--for reasons that aren't worth rehashing here. While I've got a "single desktop" solution working with Xorg + Xinerama, it is killing the 3D acceleration. I am wondering if anyone else has tried mixing & matching like this and managed to get the 3D acceleration working while still maintaining a single desktop? (No, swapping to other multi-head cards is not an option in this case--I'm in configuration management hell.) I've tried every kernel configuration I can think of, and while I found numerous ways of preventing Xorg from working, I haven't found a solution yet.
-kernel = 3.3.8
-using AMD AGPGart
-various recent Catalyst versions
-used aticonfig to establish base/working [Xorg.conf]
I know this is a desperate long shot, but I had to try. (I doubt anyone is mixing these levels of H/W... it's just not a sane combo. I'm surprised the driver can handle it at all, really.)
Thanks in advance.
