multihead matrox g550 fails with two graphic adapters (2x2)

I'm not a X-expert, but on suse-9.3 sax2 was better in detecting the two g550 matrox dual head cards (one agp, one pci). What beta3 does: On SuSE-10-Beta3 the primary/first vga-out of both graphic adapters were found and I could configure them the yast-way (xinerama...). The second vga-out is dead/not detected. The xorg.conf misses the device sections with "Screen 1". On 9.3 the second vga-out was found on both cards but the 2nd of the pci adapter faild until I modified the XF86Config. I'll attach the old XF86Config l8ters. It's on you to decide if it's a "bug" or a not supported feature. greetings, stephan
Created attachment 47519 [details] "Device Sections" of XF86Config from a 9.3 setup I changed the XF86Config build by sax2 manually to get all 4 vga-outs working on SuSE-9.3.
Created attachment 47520 [details] lspci -nv with the two matrox g550 adapters maybe this lspci help. tell me if I could help out with some other informatinos.
you are right 9.3 tried to handle that crappy mga driver in dualhead mode but 10.0 won't because the quality is even worse than on 9.3 10.0 will not support Matrox multihead environments by default. You can try to use: sax2 -b /usr/share/sax/profile/Matrox_G550 from runlevel 3 but there is no support on the result
I agree.
