Hi Danny, I'm the author of nvidia-detect.
I'm testing an installation of nvidia drivers on a HP Z4 workstation
(nvidia Quadro P600) with CentOS 6.9. Running nvidia-detect with this
setup gives the following output:
Error getting device_class
nvidia-detect scans the pci bus and checks the returned device_class for
display controllers. In your case, the scan is not returning any devices
(or rather the device_class for any pci devices)
nvidia-detect also quits with exit-code 255.
The internal error checking is displaying the above error message and
exiting with the appropriate error code, as intended.
Could this be a bug in nvidia-detect? Or is it an unsupported configuration?
Good question, and I've no idea why it's not working on your machine.
The following hardware is detected, it seems some sort of unknown
Intel device is detected by the OS:
# lspci | grep VGA
00:1f.5 Non-VGA unclassified device: Intel Corporation Device a2a4
21:00.0 VGA compatible controller: NVIDIA Corporation Device 1cb2 (rev a1)
# lspci -n | egrep '00:1f.5|21:00.0'
00:1f.5 0000: 8086:a2a4
21:00.0 0300: 10de:1cb2 (rev a1)
Tested with the following version (with equal results):
Your device is supported:
$ nvidia-detect -l | grep -i 1cb2
[10de:1cb2] NVIDIA Corporation GP107GL [Quadro P600]
Support was added in the 375.39 NVIDIA driver. I assume the driver works
as expected for you?
If you are able to offer any more clues, please feel free to open a bug
report on elrepo.org/bugs for us to track. Happy to help if I can.
