Created attachment 128489
Configuration is 8x monitors, 8x devices, 8x screens with 2x Radeon E6760 CompactPCI Boards (MEN G214)
The latest version I used was from Fedora 22, 4.2.6-200.fc22.x86_64.
I expect it was version 7.6 but I missed to save the log files.
The current configuration is CentOS 7 3.10.0-327.36.3.el7.x86_64 with module version 7.5.
I was not able to detect any failure - it just look wrong and seam to be a simple failure.
Xorg configuration is 8x monitors, 8x devices, 8x screens
with 2x Radeon E6760 CompactPCI Boards (MEN G214)
See attached Xorg.0.log.
== Result ==
Graphic Board ONE:
Monitor 1 and 2 are aktive/working - Monitor 3 and 4 is black.
Monitor 1 has Display :0.0.
Monitor 2 has Display :0.3.
Display :0.1 and :0.2 are working but not visible.
Display :0.1 and :0.2 seams to be between Monitor 1 and 2.
DisplayPort-1 will be used more often last DISPLAY is visible.
Graphic Board TWO:
Monitor 1 and 2 are aktive/working - Monitor 3 and 4 is black.
Monitor 1 has Display :0.4.
Monitor 2 has Display :0.7.
Display :0.5 and :0.6 are working but not visible.
Display :0.5 and :0.6 seams to be between Monitor 1 and 2.
DisplayPort-1 will be used more often last DISPLAY is visible.
Seams to be simple - right? I hope it is.
Please help, I don't want to use fglrx driver.
Oh, just for information - fglrx is working, but slower in our usecase.
