Installing Cryosparc, requires cuda, recommended 11.8, requires NVidia drivers.
Case 1 - Ubuntu 22.04, drivers installed, installed cuda_11.8.0_520.61.05_linux.run but # nvidia-smi
shows cuda driver 12.0, I did something wrong but not seeing where.
Case 2 - Ubuntu 20.04, drivers not installed, unclear what drivers to use, nvidia-smi tells me it can’t talk with the driver no matter what driver I try.
Tried installing cuda_11.8.0_520.61.05_linux.run but three levels of log down, in /var/log/nvidia-installer.log
I find that I think is the cause.
Please see the log entries ‘Kernel module load error’ and ‘Kernel messages’ at the end of the file ‘/var/log/nvidia-installer.log’ for more information.

Looks like apparmor - but I’ve turned it off, disabled, and rebooted.
Thanks in advance for any guidance on either gpu-enabled ubuntu machine.
