GTX 1060 with exp gdc in linux

Graphics / Linux Linux
1

Hello,
I am trying to get a gtx 1060 working as an external GPU with an old Dell studio 1555 notebook via the exp gdc adapter over expresscard.
In Ubuntu 18.04 the card is correctly recognized as a pci device with “lspci” and drivers can be installed as they should via ubuntu software center.

I installed the nvidia-driver-460.

However the card is not listet with “nvidia-smi” and the nvidia settings window does not show anything at all.

Please forgive me, I am not that linux affine, but I try my best :)

Does anybody have an idea what I could do to troubleshoot?

Thanks for your help in advance.

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

The system bios doesn’t provide enough address space to drive the gpu. Please check if setting the kernel parameter
pci=realloc
helps.

I have added this line to /etc/default/grub
However I still get “no devices were found” if I try nvidia-smi.

Is this the correct way to do it?

Thanks a lot for your support :)

Does that notebook support efi boot? If so, please try reinstalling Ubuntu in efi mode.

Unfortunately it does not.
I should note that it has a ATI Radeon card installed. Could that be a problem interfering with the nvidia driver?

I mean the card is listed under my pci Devices…

Like said, it’s not a driver problem, your system bios doesn’t support adding a second gpu, not enough address space.
Don’t know if it’s possible to disable the amd gpu.
