Ubuntu 20.10 eGPU detected and authorized but no GPU  

Did the egpu-switcher script recognize every GPU?

No, it didn't. Tt only recognizes internal GPU's (the internal RTX and AMD gpu's). 

I noticed something odd. I have a TB3 nvme enclosure from TekQ and it's also detected and authorized, but I can't at the drive either. There's no USB over TB3 ports either, using normal USB drives that were either USB-c native or USB-A with adapters. 

I guess there's a problem with my TB3 implementation?

This does sound like something wrong with the thunderbolt implementation if other devices aren't working as well. My first stop would be searching through the output of:

[Please login to see this]

for something thunderbolt related or mentioning the pcie bus address of the thunderbolt controller.

@nu_ninja, I rand sudo dmesg | grep -i thunderbolt and got this:

@raffaele_fenix_puglia, I don't speak Italian, so apologies if I interpreted this incorrectly.

You could try passing either "nomodeset" or "nouveau.modeset=0" as well as "intel_iommu=on" for boot/kernel arguments and see if that helps.

 

@dregpu

I was so stupid, I plugged in my shiny new GPU and forgot to plug in the PCIe power pins in it and wondered the same thing; "I can see the enclosure, but no GPU, hm..." 🙂
