I've been trying to set up my NVIDIA drivers on KUbuntu, but I'm not seeing anything in the NVIDIA profiles section. When I run `nvidia-smi`, I get an error message saying it couldn't communicate with the NVIDIA driver. I checked what's loaded with `lsmod | grep nvidia`, and it seems like some modules are loaded, but I'm not sure if they're the right ones. I also ran a few other commands to check the driver status and it shows that I have `nvidia-driver-590-open` installed. My GPU is a GeForce RTX 4090 Laptop GPU. Any advice on how to resolve this issue would be really appreciated!

Check if Secure Boot is enabled in your BIOS. If it is, you may have to look up the Ubuntu Wiki on Secure Boot to ensure the driver is signed. Alternatively, you could disable Secure Boot entirely to get around this issue.
You need to reboot to check if that helps. If it still doesn't work after a restart, it might be a case of an incorrect installation or possibly a compatibility issue with your GPU, but with a 4090, that shouldn't be the problem.
