I decided to re-do all the process…
I think the official guide should mention the .run trick to not install the shadow driver.
Here are the steps to install the cuda toolkit on a fresh WSL Ubuntu 18.04 install:
$ sudo apt update
$ sudo apt install build-essentials
$ sudo sh cuda_11.0.1_450.36.06_linux.run
Uncheck the nvidia driver:
Ignore the warning:
WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least .00 is required for CUDA 11.0 functionality to work.
To install the driver using this installer, run the following command, replacing with the name of this run file:
sudo .run --silent --driver
Logfile is /var/log/cuda-installer.log
$ cd /usr/local/cuda-11.0/samples/1_Utilities/deviceQuery
$ make
$ ./deviceQuery

Thank you! I would never guessed that the .run is different than the .deb cuda toolkit.
