Xorg.conf using basemosaic configuration is not extending to 8 graphics outputs

Specialized configuration with twin NVS 510 adapters need to scale a singular X screen across 8 outputs. Can provide xorg.conf and Xorg.0.log files

Please post the output of

sudo cat /sys/module/nvidia_drm/parameters/modeset

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.
