[ 112.816546] NVRM: GPU 0000:00:05.0: RmInitAdapter failed! (0x22:0x56:667)
The gpu might be broken.
Please try to reseat card in its slot, check in another system for a general hardware failure.
This O.S. is running in a Virtual Machine under Unraid, could this be because the graphics card ROM has to be modified to be accepted, by removing the NVIDIA header, or is this unrelated?
Ok, I didn’t check for a VM. This is very well possible the init failure is tied to pci passthrough, though it should work without fiddling with drivers >460 since uraid is based on KVM.
VBios modifications are not necessary, you could try using the old workaround, hiding the hypervisor. https://forums.unraid.net/topic/94498-solved-i-need-hide-vm-status-in-application/
