Hi All,
So I’m just experimenting with Linux as a workstation and the first hurdle I’m hitting is getting the eGPU going.
I’ve tried updating the xorg.conf using the nvidia-xconfig utility and then updating the PCI bus ID to “PCI:8:0:0” as per the various outputs showing the device there but not getting display on the eGPU outputs.
