Nvidia-smi "No devices were found"

Graphics / Linux Linux

What I’ve tried:

  • adding pci=nocrs,realloc,rom to /etc/default/grub
    • this helped get me from “ERROR: could not insert ‘nvidia’: No such device” to “No devices were found”.
  • echo 1 > /sys/bus/pci/devices/0000\:00\:01.0/remove ; echo 1 > /sys/bus/pci/rescan
    • Thread 197768

Hardware I have:

  • 2013 Mac Pro “Trashcan”
  • Ubuntu 20.04 with all packages updated
  • eGPU bridge 5e:00.0 PCI bridge: Intel Corporation JHL7540 Thunderbolt 3 Bridge [Titan Ridge DD 2018] (rev 06)
  • NVIDIA RTX A5000

Why can’t nvidia-smi see my GPU even though /dev/nvidia0 exists? :(

I’ve attached the nvidia-bug-report.log.gz to this post.

Also, these messages keep repeating in my dmesg log, regardless of which driver I install (470, 515, 525):

Thanks for the reply! I’ll try a version of the 470 driver in the range you mentioned. Would it work with an ampere/A series card?

Support for the RTX 5000 (desktop) was added in 460.73.01

Awesome, thanks! I’ll try that and report back.
