Bug#1088522: nouveau: Unable to boot with 3 monitors on Nvidia GPU

Cross-posted to 2 groups.

Hi,

Please provide complete file paths to check the firmware files.

If I copy /lib/modules/6.15.4-200.fc42.x86_64 from Fedora into Debian's 
/lib/modules/, can I use "sudo update-grub"  to update the grub boot 
entry or do I need to manually edit the entry?

regards,

Benjamin
