I have already blacklisted Nouveau drivers with this method

cat /etc/modprobe.d/blacklist-nvidia-nouveau.conf

blacklist nouveau
options nouveau modeset=0

I have also regenerate initramfs and rebooted

sudo update-initramfs -u

nvidia-smi shows

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

sudo apt install nvidia-390 shows

nvidia-390 is already the newest version (390.67-0ubuntu0~gpu18.04.1).
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

Besides that my nvdia x server does not launch when I click it.

I am stuck trying to install the nvidia drivers for a few days searching for possible solutions. I am a newbie trying to install cuda and cudnn for starting machine learning. Any help would be much appreciated.
