XPA 13-9380 Ubuntu Nvidia drivers not loading
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.
No Events found!

It started working this morning.
Here is what I've done:
* reinstall Ubuntu 18.04 from scratch
* use a second monitor directly from the first (top left) thunderbolt port with a USB C to HDMI (+ power) adapter
* just this morning, tried to plug the eGPU (GTX 1080 in a Razer Core) on the 2nd (bottom left) thunderbolt port : after the boot, the eGPU was not detected (same error as my 1st post)
* reboot with the eGPU connected to the 1st (top left) thunderbolt port
* eGPU is detected, and the monitor is also detected
* install the nvidia-390 drivers directly from the Ubuntu "Additional drivers" tab
* reboot
* eGPU and screens are detected...
I have no idea what I did different from my 1st install/try.
Maybe because the whole install has been performed with secure boot disabled.

Same issue here with a XPS 9380 and a Razer Core X. Currently i have tested it with a Nvidia GTX 970. I'm getting the same error message in dmesg.
Edit: I found a workaround for the issue.
If I boot the device with the egpu plugged in it does not get the necessary memory bars from kernel. You can verify this with "lspci -vv".
As soon as the egpu is then plugged to the second thunderbolt port it works.

What do you mean by "second thunderbolt port"?
Can you please provide a step by step procedure?
Thank you!

You have 2 thunderbolt ports on the left side.
I have plugged in the egpu to one of them first.
After verifying the unallocated memory bars, I insert the egpu to the other port at the notebook.
After this all memory bars are getting allocated correctly, and the egpu starts working.
