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 downloaded the local installer and installed everything but the drivers (which I already installed).
After this when I try and login, I am taken back to the login screen.
I went into TTY mode and ran
sudo nvidia-xconfig to generate. Xorg.conf file under /etc/X11.
After this I ran
startx which fails with an error message that refers to no screens. Looking at the logs
I see a reference to AllowExteralGpus and that my EGPU won’t be used unless that option has been the turned on.
I tried adding that, but running
startx with that option causes the machine to hang.
I tried adding the BusID based on
lspci but that did not help either. Is there a way to test an Xorg.conf file ?
nvidia-smi shows that both the device and the correct drivers are installed. What am I missing ? Any help or insight would be super helpful. My machine has a clean install of Ubuntu 18.04. My EGPU setup works correctly when I boot into Windows, so I don’t suspect hardware problems.
I would appreciate some help.
