Bug Description

When installing linux-modules-nvidia-418-generic using apt, I expect the nvidia driver to be available immediately after the install completes. However, I must reboot before nvidia-smi returns driver information.

AS a side note: sudo udevadm control --reload && sudo udevadm trigger does not cause the driver to appear before the reboot.

I was testing this on Disco.

System information found in attachment.

So after doing a little more digging:

A modprobe -r nouveau will fix this. After issuing this command, an install does not require a reboot for nvidia-smi to find the driver.

We are planning on blacklisting the module in our cloud images to address this.

Nouveau was blacklisted in our images, so I am no longer seeing this problem.
