I’m converting a CentOS 7 system to Lubuntu 20.04. It has 8 Nvidia 1080ti GPUs. I want to use the proprietary drivers from Canonical. That part works fine. But I also want to disable graphical mode. When I run
systemctl isolate multi-user.target, I get a blank screen on the server’s VGA port. I expect to see a text login prompt.
I want to do this so all of the GPU’s memory is available for GPU computing. This system is not used for graphics – only CUDA programs.
