Hi,

 

I'm trying to use the XPS 13 9380 with Ubuntu 18.04 and an external Nvidia GPU in a Razer Core.

I've tried the driver version 390 and 430.

I've tried the 4.15, 4.18 and 5.1.1 kernels.

But I still have the same error in `dmesg` :

 

[  118.981359] nvidia-nvlink: Nvlink Core is being initialized, major device number 511
[  118.981668] NVRM: This PCI I/O region assigned to your NVIDIA device is invalid:
               NVRM: BAR1 is 0M @ 0x0 (PCI:0000:23:00.0)
[  118.981668] NVRM: The system BIOS may have misconfigured your GPU.
[  118.981670] nvidia: probe of 0000:23:00.0 failed with error -1
[  118.981681] NVRM: The NVIDIA probe routine failed for 1 device(s).
[  118.981682] NVRM: None of the NVIDIA graphics adapters were initialized!
[  118.981768] nvidia-nvlink: Unregistered the Nvlink Core, major device number 511

Based on my research, it might be a BIOS related issue.
