I am trying to setup my Intel NUC and a GeForce 2080 RTX as an EGPU with Ubuntu 18.04. I used the ppa graphics repository to install the nvidia-driver-410 package. After that I ran: sudo prime-select nvidia After this I rebooted the machine. All was well. I decided to then setup CUDA 10.0, so I d…

That worked !! Thank you. You said using Prime meant that I am still using the Intel GPU as well. Is there something I should be using instead ?

The intel gpu is only used for display since the monitor is connected to it so the picture has to be pushed over the thunderbolt connection. Otherwise you would have to connect a monitor to the nvidia gpu.

Thank you for the clarification. You have been super helpful.

One last question. If I did connect the display directly to the GPU, what changes would I have to make ? Just set up /etc/X11/xorg.conf using nvidia-xconfig ?

None. Just switch the Monitors. You can of course also create an xorg.conf setting the nvidia gpu as single gpu but then the intel gpu won’t work anymore so X won’t start if you disconnect the egpu casing.
