I'm having trouble with my NVIDIA drivers on KUbuntu. Although I thought I installed the right ones, I'm not seeing anything in the NVIDIA profiles section. When I run the command `nvidia-smi`, I get an error saying that it can't communicate with the NVIDIA driver and suggests ensuring the latest driver is installed and running. I've checked the installed drivers using `dpkg -l | grep nvidia-driver-590`, and it looks like the NVIDIA driver (open kernel) is present. I've also run `ubuntu-drivers devices`, which shows my GPU model is a GeForce RTX 4090. However, I'm still having issues getting it to work. Any insights would be greatly appreciated!

Check if Secure Boot is enabled in your BIOS. If it is, you may need to ensure your driver is signed or consider disabling Secure Boot to get the driver to work properly.
Thanks for the tips! I did reboot, but it didn't help. As for Secure Boot, it's not enabled on my system. Should I think about enabling it or leave it as it is?
You probably just need to reboot your system to finalize the driver installation. If it still doesn't work after rebooting, it might be due to an installation mistake or possibly an unsupported card, but since you have a 4090, that shouldn't be the issue.
