I want to install CUDA toolkit and NVIDIA drivers on Ubuntu.I am starter in linux,so I have no experience.I've had worked on this for three days but problem still exists.

Firstly, I disabled Secure Boot in BIOS.After that, In grub menu, I set nomodeset quiet splash installed CUDA Toolkit 10.1 from there.And to install Nvidia drivers I applied steps given below:

$ sudo add-apt-repository ppa:graphics-drivers/ppa  
$ sudo apt update  
$sudo apt install nvidia-driver-418  
reboot

,

when nvidia-smi is entered the output is:

"NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running."

How can I solve this, thanks friends.
