I finally got Ubuntu 20.04 running on my MacBook Pro 16. Thunderbolt seems to work just fine for everything (docks and drives). When I attach my Razer Core + RTX 2080 Ti, the eGPU is recognized and authorized, but the GPU isn't recognized. The Ubuntu additional drivers thing knows there's an nvidia card and I can install the 440 drivers. However, no GPU. Nvidia-SMI says there's no drivers and communicate. Output of lspci shows the RTX2080Ti is attached. I tried logging out and logging back in, but no joy.

Any ideas? I feel like I'm so close!

Did you find anything?

I have approximately the same installation : MacBook Pro 2017 13", Razer Core X, Nvidia Rtx 2080 Ti and Ubuntu 18.04.

I have installed all drivers, the eGPU on Thunderbolt ports is recognized but nvidia-smi returns "NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running."

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Sadly, no. If you figure it out, please let me know!
