I installed Ubuntu 18.04 LTS server with Ubuntu Desktop on the Dell R740 Server. The real problem is to install the Nvidia driver on the system. The server has 2 Nvidia Tesla P40 GPU. I have tried several times but the Nvidia X server setting remains white and blank window. I tried to install a different version but cannot resolve the problem. I also tried the command sudo prime-select nvidia but the nvidia-smi shows no process running on GPU.
Really appreciate if you can share some knowledge and idea with me.
